 Please find the changelog for VictoriaMetrics Anomaly Detection below.
 
-## v1.30.0
-Released: 23-07-2026
-
-- FEATURE: Added univariate and multivariate online [Temporal Envelope](https://docs.victoriametrics.com/anomaly-detection/components/models/#temporal-envelope) models for complex time-series profiles. They combine robust causal trend, compact calendar and learned holiday behavior, changepoint adaptation, residual prediction intervals, future-horizon forecasts, and optional cross-series dependency detection in bounded state.
-
-- FEATURE: Added asynchronous [`/api/v1/autotune/tasks`](https://docs.victoriametrics.com/anomaly-detection/components/models/#shared-asynchronous-autotune-workflow) endpoints and improved unsupervised tuning with model-capability-aware objectives, optional causal exact validation for online models, constrained alert-volume selection, fitted-state complexity tie-breaking, and frozen model-specific parameters.
-
-- FEATURE: Added `/api/v1/timeseries/characteristics` for bounded analysis of trend, calendar seasonality, changepoints, gaps, and intermittent or spiky behavior across sampled query results. This improves automated model selection and search-space suggestions in both agentic workflows and [AI Copilot](https://docs.victoriametrics.com/anomaly-detection/ui/#ai-assistance)-backed [UI](https://docs.victoriametrics.com/anomaly-detection/ui/) experiments.
-
-- UI: Updated [vmanomaly UI](https://docs.victoriametrics.com/anomaly-detection/ui/) from [v1.7.2](https://docs.victoriametrics.com/anomaly-detection/ui/#v172) to [v1.8.0](https://docs.victoriametrics.com/anomaly-detection/ui/#v180). Notable mentions are model and query configuration, query prettification, fullscreen charts, out-of-date results alert and improved [AI Copilot](https://docs.victoriametrics.com/anomaly-detection/ui/#ai-assistance) suggestion and cancellation behavior.
-
-- FEATURE: Made AI-assisted configuration more reliable with reusable [vmanomaly workflow skills](https://github.com/VictoriaMetrics/skills), data-aware model suggestions, protocol-safe cancellation and synchronized query, model, and anomaly-setting updates in [UI](https://docs.victoriametrics.com/anomaly-detection/ui/).
-
-- IMPROVEMENT: Fitted history can be retained as a stronger prior through `history_strength` argument, requiring a reduced number of observations (say 2 weeks for weekly seasonality) to be effective if the history window is a good indicator of "normal" data patterns. Models supported: `mad_online`, `zscore_online`, `quantile_online`.
-
-- IMPROVEMENT: Improved bounded datasource operation with optional ad-hoc series limits, stale-series lookback caps, and propagation of configured per-query sampling periods to models and autotune trials.
-
-- IMPROVEMENT: Added `reader.fetch_timeout` and `reader.processing_timeout` for [`VmReader`](https://docs.victoriametrics.com/anomaly-detection/components/reader/#vm-reader) and [`VLogsReader`](https://docs.victoriametrics.com/anomaly-detection/components/reader/#victorialogs-reader), allowing datasource reads and post-fetch processing to be tuned *independently* while preserving `reader.timeout` as the backward-compatible default for both phases.
-
-- BUGFIX: Fixed [backtesting runs](https://docs.victoriametrics.com/anomaly-detection/components/scheduler/#backtesting-scheduler) across multiple fit cycles and for auto-tuned online wrappers, preventing duplicate or missing predictions while retaining causal model updates and restoration of compatible legacy auto-tuned state.
-
-- BUGFIX: Prevented service shutdown after a [`PeriodicScheduler`](https://docs.victoriametrics.com/anomaly-detection/components/scheduler/#periodic-scheduler) worker dies by adding bounded restart attempts with backoff and exposing restart health through [startup metrics](https://docs.victoriametrics.com/anomaly-detection/components/monitoring/#startup-metrics).

+Selecting the best model for `vmanomaly` depends on the data's nature and the [types of anomalies](https://victoriametrics.com/blog/victoriametrics-anomaly-detection-handbook-chapter-2/#categories-of-anomalies) to detect. For instance, [Z-score](https://docs.victoriametrics.com/anomaly-detection/components/models/#online-z-score) is suitable for data without trends or seasonality, while more complex patterns might require models like [Prophet](https://docs.victoriametrics.com/anomaly-detection/components/models/#prophet).
 
-- Use [Online MAD](https://docs.victoriametrics.com/anomaly-detection/components/models/#online-mad) for simple, mostly stationary data with no-to-slow trend, when robustness to outliers is important.
-- Use [Online Z-score](https://docs.victoriametrics.com/anomaly-detection/components/models/#online-z-score) for simple, light-tailed data where standard-deviation units are meaningful.
-- Use [Temporal Envelope](https://docs.victoriametrics.com/anomaly-detection/components/models/#temporal-envelope) {{% available_from "v1.30.0" anomaly %}} for complex data with trends, calendar patterns, holidays, or persistent shifts. It is the preferred *online* alternative to Prophet (which will be deprecated in the future releases).
-- Use multivariate Temporal Envelope when normal relationships between aligned metrics matter. This should replace [Isolation Forest](https://docs.victoriametrics.com/anomaly-detection/components/models/#isolation-forest-multivariate) used in previous versions of `vmanomaly`, which will be deprecated in future releases.
-- Use [Prophet](https://docs.victoriametrics.com/anomaly-detection/components/models/#prophet) when Prophet-specific decomposition outputs, or offline batch behavior are required. Consider using Temporal Envelope instead, as it is more efficient and provides better results in most cases.

 - **Optimized resource utilization**: By spreading the computational load over time and reducing peak demands, online models make more efficient use of resources and inducing less data transfer from VictoriaMetrics TSDB, improving overall system performance.
 - **Faster convergence**: Online models can adapt {{% available_from "v1.23.0" anomaly %}} to changes in data patterns more quickly, which is particularly beneficial in dynamic environments where data characteristics may shift frequently.

-Here is an example of a config file that runs the online [Temporal Envelope](https://docs.victoriametrics.com/anomaly-detection/components/models/#temporal-envelope) model on a CPU metric. The scheduler runs inference every five minutes and performs a full refit only every 100 weeks; between refits the model updates causally from each inference batch. The initial fit uses four weeks of data. The model produces `anomaly_score`, `yhat`, `yhat_lower`, and `yhat_upper` [series](https://docs.victoriametrics.com/anomaly-detection/components/models/#vmanomaly-output) for debugging, and its hour-of-day and day-of-week profiles follow the query timezone and daylight-saving-time changes.

-#### Shared asynchronous autotune workflow
-
-{{% available_from "v1.30.0" anomaly %}} Agents, the UI, and external automation can tune one shared configuration across a bounded sample of query results without adding an `auto` wrapper to the production configuration:
-
-1. Inspect the query with `GET /api/v1/timeseries/characteristics` to identify trend, calendar seasonality, changepoints, gaps, and intermittent behavior.
-2. Start a task with `POST /api/v1/autotune/tasks`. Provide the actual query, the candidate model class, the same query `step` used in production, and a bounded `limit`.
-3. Poll `GET /api/v1/autotune/tasks/{task_id}` until `status` is `done`; cancel unnecessary work with `DELETE` on the same path.
-4. Validate and deploy `result_data.data.modelConfig`, which is a concrete configuration for the selected model class.
-
-> [!TIP]
-> Use [skills](https://docs.victoriametrics.com/ai-tools/#agent-skills) where abovementioned workflow is automated. Also, [AI Copilot](https://docs.victoriametrics.com/anomaly-detection/ui/#ai-assistant) can generate a tuned model configuration to interactively backtest in UI, based on the query data characteristics and user's anomaly expectations.
-
-Example request for an online model:
-
-```json
-{
-  "query": "sum(rate(http_requests_total[5m])) by (service)",
-  "tuned_class_name": "temporal_envelope",
-  "anomaly_percentage": 0.01,
-  "step": "5m",
-  "limit": 100,
-  "use_profile_hints": true,
-  "optimization_params": {
-    "exact": true,
-    "n_splits": 3,
-    "n_trials": 64,
-    "timeout": 60,
-    "optimize_complexity": true
-  },
-  "frozen_params": {
-    "holidays": {"countries": ["US"], "group": true}
-  }
-}
-```
-
-The requested anomaly percentage is treated as an alert-volume constraint rather than a target that must be reached in every validation fold. Model-specific search ranges may be narrowed using the sampled characteristics, while `frozen_params` preserves operator-supplied context. For online models, `exact: true` usually gives the most representative choice when production inference is causal.
-
 > There are some expected limitations of Autotune mode:
 > - It can't be made on your [custom model](#custom-model-guide).
 > - It can't be applied to itself (like `tuned_class_name: 'model.auto.AutoTunedModel'`)
+> - `AutoTunedModel` can't be used on [rolling models](https://docs.victoriametrics.com/anomaly-detection/components/models/#rolling-models) like [`RollingQuantile`](https://docs.victoriametrics.com/anomaly-detection/components/models/#rolling-quantile) in combination with [on-disk model storage mode](https://docs.victoriametrics.com/anomaly-detection/faq/#on-disk-mode), as the rolling models exists only during `infer` calls and aren't persisted neither in RAM, nor on disk.
 
 
-### Temporal Envelope
-
-{{% available_from "v1.30.0" anomaly %}} Temporal Envelope is the preferred online model for complex operational and business metrics. It learns an evolving expected range from robust trend, calendar and holiday patterns, persistent level shifts, uncertainty, and optional future forecasts. The model adapts during inference while limiting the lasting influence of short-lived spikes.
-
-> `TemporalEnvelopeModel` is [univariate](#univariate-models) and [online](#online-models). `TemporalEnvelopeMultivariateModel` also learns normal cross-series relationships as a [multivariate](#multivariate-models) model.
-
-Use it for:
-
-- infrastructure, application, or business metrics with trends and daily, weekly, monthly, or holiday behavior;
-- deployments, traffic migrations, and capacity changes that create persistent shifts, including short-horizon forecasts through `forecast_at`;
-- aligned related metrics where each channel keeps its own temporal pattern while their joint behavior contributes to one anomaly score.
-
-For simple profiles without strong trend or seasonality, prefer [Online MAD](#online-mad) or [Online Z-score](#online-z-score). [Prophet](#prophet) and [Isolation Forest](#isolation-forest-multivariate) remain offline alternatives when their distinct capabilities are required or validation favors them.

-
-- `class` (string) - `temporal_envelope` or the full class name `model.online.TemporalEnvelopeModel`.
-- `quantiles` (list[float], default `[0.25, 0.75]`) - two ordered probabilities used as the base lower and upper residual boundaries. Values must be within `[0, 1]`.
-- `iqr_threshold` (float, default `2.0`) - primary data-derived interval-width control. Higher values widen the ordinary residual envelope and produce fewer detections. Values from `1` to `4` are a practical experimentation range.
-- `alpha` (float, default `0.005`) - **Trend Reactivity**. Higher values follow persistent level and trend changes faster; lower values produce steadier expectations. Values from `0.0025` to `0.02` are a practical experimentation range.
-- `loss_reactivity` (float, default `5.0`) - controls how readily new deviations influence the model. Higher values adapt more readily; lower values reduce the influence of spikes. Values from `1` to `5` are a good starting range.
-- `min_n_samples_seen` (integer, default `16`) - observations each model or group must see before anomaly scores are trusted. State and forecasts continue learning during warmup, while anomaly scores remain zero. Approximate warmup duration is this value multiplied by the query step.
-- `changepoint_window` (integer, default `16`) - consecutive same-direction residuals required before treating a deviation as a persistent level shift. Use a value longer than ordinary anomaly bursts; approximate confirmation time is this value multiplied by the query step.
-- `seasonalities` (list[string], default `['hod_smooth', 'dow_smooth']`) - recurring calendar patterns to model. Use an empty list when calendar patterns are known to be irrelevant. Supported presets are:
-  - hour of day: `hod_smooth`, `hod_spiky`, `hod_plateau`;
-  - day of week: `dow_smooth`, `dow_spiky`, `dow_plateau`;
-  - weekday versus weekend: `weekpart_plateau`;
-  - month of year: `month_smooth`, `month_plateau`.
-- `holidays` (object, default `{}`) - known country holidays and special events. Supported keys are `countries` (country codes or names), `special_events` (recurring `MM-DD` or one-off `YYYY-MM-DD` dates), and `group` (whether configured events share one learned response). Holiday response shape is learned from data rather than configured publicly.
-- `forecast_at` (list[string], default `[]`) - positive future offsets such as `['1h', '1d']`. Each offset adds point and, when requested through `provide_series`, lower and upper forecast series.
-
-Preset suffixes describe expected profile shape: `smooth` represents gradual recurring curves, `spiky` represents narrow phase peaks, and `plateau` represents sustained calendar levels. Choose only profiles supported by the data. Calendar and holiday features use civil time from the configured query timezone, so hour/day profiles remain aligned across daylight-saving-time transitions.
-
-Temporal Envelope also supports the [common model arguments](#common-args), including `queries`, `schedulers`, `provide_series`, `detection_direction`, `scale`, `clip_predictions`, `min_dev_from_expected`, and `min_rel_dev_from_expected`. Input `data_range` and query timezone are configured on the [reader](https://docs.victoriametrics.com/anomaly-detection/components/reader/#config-parameters).
-
-The multivariate variant uses `class: temporal_envelope_multivariate` or `model.online.TemporalEnvelopeMultivariateModel` and adds:
-
-- `dependency_rank` (integer, default `8`) - compact rank used to represent cross-channel dependencies. Set it to `0` to disable dependency features.
-- `score_aggregation` (`max`, `mean`, or `l2`; default `l2`) - combines per-channel boundary deviations into one anomaly score. `l2` uses their root-mean-square magnitude.
-- `groupby` (list[string], optional) - metric label names used to fit a separate multivariate model for each unique label-value combination.
-- `max_channels` (integer, default `1000`) - hard safety limit for input time series in one model instance.
-- `recommended_max_channels` (integer, default `100`) - advisory limit; larger inputs up to `max_channels` are accepted with a warning because high-dimensional estimates may be less stable and more expensive.
-- `random_state` (integer, default `42`) - seed used for reproducible dependency features.
-
-The multivariate model emits only the joint `anomaly_score` by default to keep output cardinality bounded. Explicitly request channel-level `y`, `yhat`, `yhat_lower`, and `yhat_upper` families through `provide_series` only when those diagnostics are needed and the downstream cardinality is acceptable.

E.g. if `start_from` is set to `20:00` and the service is started and then terminated and restarted at `20:30`, it will not produce any anomaly scores until the next day's `20:00` is reached (+23:30 of being idle), which introduces inconvenience for the users.

-Several VictoriaMetrics components can connect to cloud storage to read or write object data.
-
-The following table shows the supported types of storage for each component:
-
-| Component | AWS S3 and S3-compatible | Google Cloud Storage | Azure Blob Storage |
-|-----------|----|----------------------|--------------------|
-| [vmbackup](https://docs.victoriametrics.com/victoriametrics/vmbackup/) | ✅ | ✅ | ✅ |

-
-All these components use the same underlying libraries, so the authentication setup is largely the same. The main difference is in the command-line flags: 
-
-- vmalert uses `-s3.*` prefixed flags (e.g., `-s3.credsFilePath`)
-- backup and restore tools use unprefixed flags (e.g., `-credsFilePath`)
-
-See the [component reference](https://docs.victoriametrics.com/guides/connecting-vm-components-to-cloud-storage/#per-component-flag-reference) for details.
-
-## Obtaining credentials
-
-You need to supply credentials so the component can connect to the cloud storage. The setup differs by provider; the sections below cover AWS S3, S3‑compatible systems, GCS, and Azure Blob Storage.
-
-### AWS S3
-
-1. In AWS, [create an IAM user](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_users_create.html) or role with the minimum permissions for the target bucket (see table below).
-1. [Create an access key](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_credentials_access-keys.html) for that IAM identity.
-1. Copy the **Access key ID** and **Secret access key** values. You will use them in the credentials file or environment variables.
-
-| Component       | S3 usage                                                    | Minimum S3 permissions |
-|-----------------|-------------------------------------------------------------|------------------------|
-| vmalert (Enterprise) | Reads alerting/recording rules from bucket.    | `s3:GetObject`, `s3:ListBucket` on the rules bucket/prefix.|
-| vmrestore       | Restores backups from S3 buckets                            | `s3:GetObject`, `s3:ListBucket` on the backup bucket/prefix.|
-| vmbackup        | Uploads backups to S3 and may delete old backup objects during maintenance.| `s3:PutObject`, `s3:GetObject`, `s3:ListBucket`, `s3:DeleteObject` on the backup bucket/prefix.|
-| vmbackupmanager (Enterprise) | Automates backups using vmbackup behavior.                  | Same as vmbackup. |
-
-
-### S3-compatible storage (MinIO, Ceph)
-
-Generate access keys using your storage system's admin interface or CLI. The credentials follow the same format as AWS S3.
-
-### Google Cloud Storage
-
-1. Open the Google Cloud Console and go to **IAM & Admin > Service Accounts**.
-1. Click **Create service account**, enter a name, and assign a Storage role (for example, Storage Object Admin).
-1. Open the service account, go to **Keys**, then click **Add key > Create new key**.
-1. Choose **JSON** as the key type and click **Create**.
-1. Store the JSON file on the machine running the VictoriaMetrics component.
-
-### Azure Blob Storage
-
-> Azure does not use credential files.
-
-1. Log in to the Azure Portal.
-1. Search for and select **Storage accounts**.
-1. Click on your specific storage account name. (This is your `AZURE_STORAGE_ACCOUNT_NAME`).
-1. In the left menu under **Security + networking**, click **Access keys**.
-1. Copy the key value from either **key1** or **key2** (this is your `AZURE_STORAGE_ACCOUNT_KEY`).
-1. Define the access keys as environment variables.
-    ```sh
-    export AZURE_STORAGE_ACCOUNT_NAME=mystorageaccount
-    export AZURE_STORAGE_ACCOUNT_KEY=myaccountkey
-    ```
-
-## Authenticating with the cloud provider
-
-Provide the credentials as a file or with environment variables, along with the path to the cloud storage bucket. The syntax for the bucket name depends on the cloud provider:
-
-- `s3://`: for AWS S3 and self-hosted S3-compatible storage (MinIO, Ceph)
-- `gs://`: Google Cloud Storage
-- `azblob://`: Azure Blob Storage
-
-### vmbackup and vmrestore
-
-The following example backups to an AWS S3 bucket using a credentials file:
-
-```sh
-vmbackup \
-  -storageDataPath=/data \
-  -snapshot.createURL=http://localhost:8428/snapshot/create \
-  -dst=s3://victoriametrics-backup/backup01 \
-  -credsFilePath=/etc/credentials
-```
-
-In order to restore from the same backup from AWS S3:
-
-```sh
-vmrestore \
-  -src=s3://victoriametrics-backup/backup01 \
-  -storageDataPath=/data \
-  -credsFilePath=/etc/credentials
-
-```
-
-> To use non-AWS S3 buckets such as MinIO or Ceph, you must [supply the `-customS3Endpoint` argument](https://docs.victoriametrics.com/guides/connecting-vm-components-to-cloud-storage/#s3-compatible).
-
-Alternatively, you can set the access keys as environment variables instead of using a credential file:
-
-```sh
-export AWS_ACCESS_KEY_ID=YOUR_AWS_ACCESS_KEY
-export AWS_SECRET_ACCESS_KEY=YOUR_SECRET_AWS_ACCESS_KEY
-
-vmbackup \
-  -storageDataPath=/data \
-  -snapshot.createURL=http://localhost:8428/snapshot/create \
-  -dst=s3://victoriametrics-backup/backup01
-
-vmrestore \
-  -src=s3://victoriametrics-backup/backup01 \
-  -storageDataPath=/data
-```
-
-
-Backups on Google Cloud Storage use the `gs://` prefix in the destination:
-
-```sh
-vmbackup \
-  -storageDataPath=/data \
-  -snapshot.createURL=http://localhost:8428/snapshot/create \
-  -dst=gs://victoriametrics-backup/backup01 \
-  -credsFilePath=/etc/credentials
-```
-
-You can restore this backup with:
-
-```sh
-vmrestore \
-  -src=gs://victoriametrics-backup/backup01 \
-  -storageDataPath=/data \
-  -credsFilePath=/etc/credentials
-```
-
-On Google Cloud, you can define the path to the JSON credential file with `GOOGLE_APPLICATION_CREDENTIALS`. For example:
-
-```sh
-export GOOGLE_APPLICATION_CREDENTIALS=/etc/credentials
-
-vmbackup \
-  -storageDataPath=/data \
-  -snapshot.createURL=http://localhost:8428/snapshot/create \
-  -dst=gs://victoriametrics-backup/backup01
-
-vmrestore \
-  -src=gs://victoriametrics-backup/backup01 \
-  -storageDataPath=/data
-```
-
-For Azure Blob Storage, use the `azblob://` prefix and rely on environment variables instead of `-credsFilePath`.
-
-```sh
-export AZURE_STORAGE_ACCOUNT_NAME=myaccount
-export AZURE_STORAGE_ACCOUNT_KEY=mykey
-
-vmbackup \
-  -storageDataPath=/data \
-  -snapshot.createURL=http://localhost:8428/snapshot/create \
-  -dst=azblob://victoriametrics-backup/backup01
-
-vmrestore \
-  -src=azblob://victoriametrics-backup/backup01 \
-  -storageDataPath=/data
-```
-
-### vmbackupmanager 
-
-> vmbackupmanager only works in the [Enterprise](https://docs.victoriametrics.com/victoriametrics/enterprise/) edition.
-
-To manage backups with vmbackupmanager on AWS S3, add the credentials with the `-credsFilePath` flag:
-
-```sh
-vmbackupmanager \
-  -dst=s3://vmstorage-data/backups \
-  -credsFilePath=/etc/credentials \
-  -storageDataPath=/vmstorage-data \
-  -snapshot.createURL=http://vmstorage:8482/snapshot/create \
-  -licenseFile=/etc/vm-license
-```
-
-Or define the access keys using environment variables:
-
-```sh
-export AWS_ACCESS_KEY_ID=YOUR_AWS_ACCESS_KEY
-export AWS_SECRET_ACCESS_KEY=YOUR_SECRET_AWS_ACCESS_KEY
-
-vmbackupmanager \
-  -dst=s3://vmstorage-data/backups \
-  -storageDataPath=/vmstorage-data \
-  -snapshot.createURL=http://vmstorage:8482/snapshot/create \
-  -licenseFile=/etc/vm-license
-```
-
-> To use non-AWS S3 buckets, you must [supply the `-customS3Endpoint` argument](#s3-compatible).
-
-Automated backups on Google Cloud Storage take the following form:
-
-```sh
-vmbackupmanager \
-  -dst=gs://vmstorage-data/backups \
-  -credsFilePath=/etc/credentials \
-  -storageDataPath=/vmstorage-data \
-  -snapshot.createURL=http://vmstorage:8482/snapshot/create \
-  -licenseFile=/etc/vm-license
-```
-
-As with vmbackup and vmrestore, you can also define the path to the JSON credential file with `GOOGLE_APPLICATION_CREDENTIALS`:
-
-```sh
-export GOOGLE_APPLICATION_CREDENTIALS=/etc/credentials
-
-vmbackupmanager \
-  -dst=gs://vmstorage-data/backups \
-  -storageDataPath=/vmstorage-data \
-  -snapshot.createURL=http://vmstorage:8482/snapshot/create \
-  -licenseFile=/etc/vm-license
-```
-
-vmbackupmanager can also use Azure Blob Storage by defining environment variables:
-
-```sh
-export AZURE_STORAGE_ACCOUNT_NAME=mystorageaccount
-export AZURE_STORAGE_ACCOUNT_KEY=myaccountkey
-
-vmbackupmanager \
-  -dst=azblob://vmstorage-data/backups \
-  -storageDataPath=/vmstorage-data \
-  -snapshot.createURL=http://vmstorage:8482/snapshot/create \
-  -licenseFile=/etc/vm-license
-```
-
-### vmalert
-
-> - vmalert cloud storage command line flags are prefixed with `-s3.` for S3 buckets *and* Google Cloud Storage.
-> - Cloud storage only works in the [Enterprise](https://docs.victoriametrics.com/victoriametrics/enterprise/) edition.
-
-Read alerting rules from an S3 bucket. The `-rule` flag accepts a prefix, so it matches all files starting with `alerts_` in the `rules` folder:
-
-```sh
-vmalert \
-  -rule=s3://my-alert-bucket/rules/alerts_ \
-  -s3.credsFilePath=/etc/vmalert/aws-credentials \
-  -datasource.url=http://vmselect:8481/select/0/prometheus \
-  -notifier.url=http://alertmanager:9093 \
-  -licenseFile=/etc/vm-license
-```
-
-Instead of a credential file, you can supply the access keys using environment variables:
-
-```sh
-export AWS_ACCESS_KEY_ID=YOUR_AWS_ACCESS_KEY
-export AWS_SECRET_ACCESS_KEY=YOUR_SECRET_AWS_ACCESS_KEY
-
-vmalert \
-  -rule=s3://my-alert-bucket/rules/alerts_ \
-  -datasource.url=http://vmselect:8481/select/0/prometheus \
-  -notifier.url=http://alertmanager:9093 \
-  -licenseFile=/etc/vm-license
-```
-
-> To use non-AWS S3 buckets, you must [supply the `-s3.customEndpoint` argument](#s3-compatible).
-
-To read rules from Google Cloud Storage:
-
-```sh
-vmalert \
-  -rule=gs://my-alert-bucket/rules/alerts_ \
-  -s3.credsFilePath=/etc/vmalert/gcp-service-account.json \
-  -datasource.url=http://vmselect:8481/select/0/prometheus \
-  -notifier.url=http://alertmanager:9093 \
-  -licenseFile=/etc/vm-license
-```
-
-If you prefer, you can supply the path to the JSON credential file with the `GOOGLE_APPLICATION_CREDENTIALS` environment variable:
-
-```sh
-export GOOGLE_APPLICATION_CREDENTIALS=/etc/credentials
-
-vmalert \
-  -rule=gs://my-alert-bucket/rules/alerts_ \
-  -datasource.url=http://vmselect:8481/select/0/prometheus \
-  -notifier.url=http://alertmanager:9093 \
-  -licenseFile=/etc/vm-license
-```
-
-## Credentials files format
-
-The file format depends on the storage provider.
-
-### S3 credentials
-
-The file uses the standard AWS shared credentials format used by the [AWS CLI](https://docs.aws.amazon.com/cli/v1/userguide/cli-configure-files.html) and [AWS SDKs](https://docs.aws.amazon.com/sdkref/latest/guide/file-format.html):
-
-```ini
-[default]
-aws_access_key_id=YOUR_AWS_ACCESS_KEY
-aws_secret_access_key=YOUR_AWS_SECRET_ACCESS_KEY
-```
-
-You can define multiple profiles in a single file:
-
-```ini
-[default]
-aws_access_key_id=DEFAULT_ACCESS_KEY
-aws_secret_access_key=DEFAULT_SECRET_KEY
-
-[monitoring]
-aws_access_key_id=MONITORING_ACCESS_KEY
-aws_secret_access_key=MONITORING_SECRET_KEY
-
-[alerts]
-aws_access_key_id=ALERTS_ACCESS_KEY
-aws_secret_access_key=ALERTS_SECRET_KEY
-```
-
-Use the `-configProfile` flag (or `-s3.configProfile` in vmalert) to select a non-default profile:
-
-```sh
--configProfile=alerts
-```
-
-You can separate credentials from other configuration settings. Put credentials in one file:
-
-```ini
-[default]
-aws_access_key_id=DEFAULT_ACCESS_KEY
-aws_secret_access_key=DEFAULT_SECRET_KEY
-```
-
-And non-sensitive settings in another:
-
-```ini
-[default]
-region=us-east-1
-```
-
-Then pass both files:
-
-```sh
--configFilePath=/etc/aws-config \
--credsFilePath=/etc/credentials
-```
-
-### GCS credentials file format
-
-The file is the JSON key downloaded from Google Cloud Console. Its content looks like this:
-
-```json
-{
-  "type": "service_account",
-  "project_id": "project-id",
-  "private_key_id": "key-id",
-  "private_key": "-----BEGIN PRIVATE KEY-----\nprivate-key\n-----END PRIVATE KEY-----\n",
-  "client_email": "service-account-email",
-  "client_id": "client-id",
-  "auth_uri": "https://accounts.google.com/o/oauth2/auth",
-  "token_uri": "https://accounts.google.com/o/oauth2/token",
-  "auth_provider_x509_cert_url": "https://www.googleapis.com/oauth2/v1/certs",
-  "client_x509_cert_url": "https://www.googleapis.com/robot/v1/metadata/x509/service-account-email"
-}
-```
-
-This is the standard service account key format defined by [Google Cloud IAM](https://developers.google.com/workspace/guides/create-credentials).
-
-### Azure Blob Storage
-
-Azure does not support credentials via file. Use environment variables instead.
-
-```sh
-export AZURE_STORAGE_ACCOUNT_NAME=mystorageaccount
-export AZURE_STORAGE_ACCOUNT_KEY=myaccountkey
-```
-
-## Self-hosted and S3-compatible endpoints
-
-For S3-compatible storage such as MinIO or Ceph, set a custom endpoint with the `-customS3Endpoint` flag  for vmbackup, vmrestore, and vmbackupmanager. For example:
-
-```sh
-vmbackup \
-  -storageDataPath=/data \
-  -snapshot.createURL=http://localhost:8428/snapshot/create \
-  -dst=s3://victoriametrics-backup/backup01 \
-  -customS3Endpoint=http://minio.example.local:9000
-```
-
-On vmalert, use the `-s3.customEndpoint` flag instead:
-
-```sh
-vmalert \
-  -rule=s3://my-alert-bucket/rules/alerts_ \
-  -s3.customEndpoint=http://minio.example.local:9000 \
-  -s3.credsFilePath=/etc/vmalert/aws-credentials \
-  -datasource.url=http://vmselect:8481/select/0/prometheus \
-  -notifier.url=http://alertmanager:9093 \
-  -licenseFile=/etc/vm-license
-```
-
-### Addressing S3-compatible buckets {#s3-compatible}
-
-When connecting to non-AWS S3-compatible buckets, there is an additional flag you might need to configure:
-
-- `-s3ForcePathStyle`: on vmbackupmanager, vmbackup, and vmrestore.
-- `-s3.forcePathStyle`: on vmalert.
-
-The flag changes the expected URL pattern for a bucket.
-
-| Flag value | Address-style | Example | Use with |
-|------------|---------------|---------|----------|
-| `true` (default) | Path-style | `https://endpoint/bucket/key` |  MinIO, Ceph, most S3-compatible storages |
-| `false`        | Virtual host-style | `https://bucket.endpoint/key` | [Aliyun OSS](https://www.aliyun.com/product/oss) and other endpoints that require it |
-
-> The flag only takes effect when you use a custom endpoint (`-customS3Endpoint` or `-s3.customEndpoint` on vmalert). When connecting to real AWS S3, the SDK handles addressing automatically.
-
-## Per-component flag reference
-
-The table below shows how the same concept maps to different flag names across components.
-
-| Concept | vmalert | vmbackup, vmrestore, and vmbackupmanager |
-|---|---|---|---|---|
-| Credentials file | `-s3.credsFilePath` | `-credsFilePath` |
-| Config file | `-s3.configFilePath` | `-configFilePath` |
-| Profile selection | `-s3.configProfile` | `-configProfile` |
-| Custom endpoint | `-s3.customEndpoint` | `-customS3Endpoint` |
-| Force path style | `-s3.forcePathStyle` | `-s3ForcePathStyle` |
-| TLS insecure | N/A | `-s3TLSInsecureSkipVerify` |
-| Storage class | N/A | `-s3StorageClass` |

-best practices for running VictoriaMetrics in production.
-
-## Try it locally
-
-The fastest way to try VictoriaMetrics on your own machine is its binary - the only thing needed to run it.
-
-### Step 1: Download the binary
-
-Create a directory for this test drive, so all the files created along the way stay in one place:
-
-```sh
-mkdir vm-quick-start && cd vm-quick-start
-```
-
-Download the `victoria-metrics-<os>-<arch>-<version>.tar.gz` archive for your OS and architecture
-from the [releases page](https://github.com/VictoriaMetrics/VictoriaMetrics/releases/latest)
-and unpack it. It contains a single `victoria-metrics-prod` binary.
-
-For example, on Linux with `amd64` architecture:
-
-```sh
-wget https://github.com/VictoriaMetrics/VictoriaMetrics/releases/download/v1.148.0/victoria-metrics-linux-amd64-v1.148.0.tar.gz
-tar xzf victoria-metrics-linux-amd64-v1.148.0.tar.gz
-```
-
-The binary is self-contained and requires no installation - it is ready to run as is.
-
-### Step 2: Start VictoriaMetrics
-
-Starting VictoriaMetrics is as simple as executing the binary, with no arguments at all.
-But since it is nicer to have some data to explore right after the start, let's also enable self-scraping
-via the `-selfScrapeInterval` command-line flag, so VictoriaMetrics collects metrics about itself:
-
-```sh
-./victoria-metrics-prod -selfScrapeInterval=10s
-```
-
-VictoriaMetrics prints a couple of dozen log lines on start, describing the storage, caches
-and memory limits it sets up. Look for these two lines confirming that it is up and running:
-
-```sh

-```
-
-That's it - VictoriaMetrics is running, listening on port `8428` and scraping its own metrics
-(CPU and memory usage, the number of stored metrics, request rates, etc.) every 10 seconds.
-If you list the `vm-quick-start` directory, you can see a new `victoria-metrics-data` directory
-created next to the binary - this is where the collected data is stored.
-
-Now that metrics are being collected, it's time to look at them.
-
-### Step 3: Explore the metrics
-
-Open [http://localhost:8428/vmui](http://localhost:8428/vmui) in your browser to access [vmui](https://docs.victoriametrics.com/victoriametrics/single-server-victoriametrics/#vmui) -
-the built-in UI for querying and graphing metrics. You should see its query page:
-
-![vmui query page](quick-start-vmui.webp)
-
-Self-scraped metrics become queryable within ~30 seconds after the start.
-
-Try the following:
-
-* Open the [metrics explorer](https://docs.victoriametrics.com/victoriametrics/single-server-victoriametrics/#metrics-explorer)
-  at [http://localhost:8428/vmui/#/metrics](http://localhost:8428/vmui/#/metrics) to browse all collected metrics;
-* Enter a query in the input field at [http://localhost:8428/vmui](http://localhost:8428/vmui) and press `Enter`. For example:
-  * `process_resident_memory_bytes` - memory used by VictoriaMetrics;
-  * `rate(process_cpu_seconds_total)` - its CPU usage;
-  * `vm_rows{type=~"storage/.+"}` - the number of stored [raw samples](https://docs.victoriametrics.com/victoriametrics/keyconcepts/#raw-samples).
-
-Queries are written in [MetricsQL](https://docs.victoriametrics.com/victoriametrics/metricsql/) -
-a PromQL-compatible query language, so any PromQL query works here as well.
-
-So far the only available metrics are the ones VictoriaMetrics reports about itself - let's collect something more interesting.
-
-### Step 4 (optional): Collect metrics from your system
-
-Self-scraped metrics only describe VictoriaMetrics itself. To monitor your machine (CPU, memory, disk, network),
-run [node_exporter](https://github.com/prometheus/node_exporter) - the standard Prometheus exporter for host metrics -
-and let VictoriaMetrics scrape it. Single-node VictoriaMetrics has a built-in
-[Prometheus-compatible scraper](https://docs.victoriametrics.com/victoriametrics/single-server-victoriametrics/#how-to-scrape-prometheus-exporters-such-as-node-exporter),
-so no other components are needed.
-
-1. Download the `node_exporter-<version>.<os>-<arch>.tar.gz` archive for your OS and architecture
-   from the [releases page](https://github.com/prometheus/node_exporter/releases/latest) and unpack it.
-   For example, on Linux with `amd64` architecture:
-
-   ```sh
-   wget https://github.com/prometheus/node_exporter/releases/download/v1.12.0/node_exporter-1.12.0.linux-amd64.tar.gz
-   tar xzf node_exporter-1.12.0.linux-amd64.tar.gz
-   ```
-
-   Unlike VictoriaMetrics, it unpacks into its own directory. Start it from there:
-
-   ```sh
-   ./node_exporter-1.12.0.linux-amd64/node_exporter
-   ```
-
-   It exposes host metrics at [http://localhost:9100/metrics](http://localhost:9100/metrics).
-
-1. Create a `scrape.yaml` file with the following contents:
-
-   ```yaml
-   scrape_configs:
-   - job_name: node-exporter
-     static_configs:
-     - targets:
-       - localhost:9100
-   ```
-
-1. Restart VictoriaMetrics with the `-promscrape.config` command-line flag pointing to this file:
-
-   ```sh
-   ./victoria-metrics-prod -selfScrapeInterval=10s -promscrape.config=scrape.yaml
-   ```
-
-Check [http://localhost:8428/targets](http://localhost:8428/targets) - the `node-exporter` target should have `state: up`.
-The target shows up as `state: down` until the first scrape happens, which can take some seconds -
-just reload the page a bit later.
-Now query host metrics in [vmui](http://localhost:8428/vmui). For example:
-
-* `node_memory_MemAvailable_bytes` - available memory on your machine;
-* `100 - avg(rate(node_cpu_seconds_total{mode="idle"})) * 100` - overall CPU usage in percent.
-
-See [scrape config examples](https://docs.victoriametrics.com/victoriametrics/scrape_config_examples/) for more advanced scrape configurations.
-
-Scraping pulls metrics from targets, but it is not the only way to get data in - metrics can also be pushed directly.
-
-### Step 5 (optional): Push your own metrics
-
-VictoriaMetrics also accepts metrics pushed via [many popular protocols](https://docs.victoriametrics.com/victoriametrics/keyconcepts/#push-model).
-For example, insert a measurement using the InfluxDB line protocol with a plain `curl` command:
-
-```sh
-curl -d 'room_temperature,room=kitchen value=21.5' http://localhost:8428/write
-```
-
-Then query `room_temperature_value` in [vmui](http://localhost:8428/vmui) to see it.
-Take into account that freshly ingested data can take up to 30 seconds to show up in query results,
-so don't worry if it doesn't appear immediately - just retry the query a bit later.
-
-Once you're done experimenting, tidying everything up takes a single command.
-
-### Cleanup
-
-Stop VictoriaMetrics and node_exporter with `Ctrl+C` in their respective terminals. All the collected data lives in the `victoria-metrics-data` directory -
-delete it if you want to start from scratch. To remove all traces of this test drive,
-delete the whole `vm-quick-start` directory created at [step 1](https://docs.victoriametrics.com/victoriametrics/quick-start/#step-1-download-the-binary).
-
-This test drive only scratches the surface of what VictoriaMetrics can do. Ready for a real setup?
-Continue with the installation options below, or learn the [key concepts](https://docs.victoriametrics.com/victoriametrics/keyconcepts/)
-of writing and querying data first.

+* For AWS S3 compatible storages set env variable `AWS_ACCESS_KEY_ID` and `AWS_SECRET_ACCESS_KEY`.
+  Also you can set env variable `AWS_SHARED_CREDENTIALS_FILE` with path to credentials file.
+* For GCE cloud storage set env variable `GOOGLE_APPLICATION_CREDENTIALS` with path to credentials file.
+* For Azure storage use one of these env variables:
+  * `AZURE_STORAGE_ACCOUNT_CONNECTION_STRING`: use a connection string (must be either SAS Token or Account/Key)
+  * `AZURE_STORAGE_ACCOUNT_NAME` and `AZURE_STORAGE_ACCOUNT_KEY`: use a specific account name and key (either primary or secondary)
+  * `AZURE_USE_DEFAULT_CREDENTIAL` and `AZURE_STORAGE_ACCOUNT_NAME`: use the `DefaultAzureCredential` to allow the Azure library
+     to search for multiple options (for example, managed identity related variables). Note that if multiple credentials are available,
+     it is required to specify the `AZURE_CLIENT_ID` to select specific credentials.
+
+  The `AZURE_STORAGE_DOMAIN` can be used for optionally overriding the default domain for the Azure storage service.
+
+Please, note that `vmbackup` will use credentials provided by cloud providers metadata service [when applicable](https://docs.victoriametrics.com/victoriametrics/vmbackup/#using-cloud-providers-metadata-service).

-     Supports the following optional suffixes for size values: KB, MB, GB, TB, KiB, MiB, GiB, TiB (default 16777216)
-  -promscrape.minResponseSizeForStreamParse size
-     The minimum target response size for automatic switching to stream parsing mode, which can reduce memory usage. See https://docs.victoriametrics.com/victoriametrics/vmagent/#stream-parsing-mode
-     Supports the following optional suffixes for size values: KB, MB, GB, TB, KiB, MiB, GiB, TiB (default 1000000)
-  -promscrape.noStaleMarkers
-     Whether to disable sending Prometheus stale markers for metrics when scrape target disappears. This option may reduce memory usage if stale markers aren't needed for your setup. This option also disables populating the scrape_series_added metric. See https://prometheus.io/docs/concepts/jobs_instances/#automatically-generated-labels-and-time-series
-  -promscrape.nomad.waitTime duration
-     Wait time used by Nomad service discovery. Default value is used if not set
-  -promscrape.nomadSDCheckInterval duration
-     Interval for checking for changes in Nomad. This works only if nomad_sd_configs is configured in '-promscrape.config' file. See https://docs.victoriametrics.com/victoriametrics/sd_configs/#nomad_sd_configs for details (default 30s)
-  -promscrape.openstackSDCheckInterval duration
-     Interval for checking for changes in openstack API server. This works only if openstack_sd_configs is configured in '-promscrape.config' file. See https://docs.victoriametrics.com/victoriametrics/sd_configs/#openstack_sd_configs for details (default 30s)
-  -promscrape.ovhcloudSDCheckInterval duration
-     Interval for checking for changes in OVH Cloud API. This works only if ovhcloud_sd_configs is configured in '-promscrape.config' file. See https://docs.victoriametrics.com/victoriametrics/sd_configs/#ovhcloud_sd_configs for details (default 30s)
-  -promscrape.puppetdbSDCheckInterval duration
-     Interval for checking for changes in PuppetDB API. This works only if puppetdb_sd_configs is configured in '-promscrape.config' file. See https://docs.victoriametrics.com/victoriametrics/sd_configs/#puppetdb_sd_configs for details (default 30s)
-  -promscrape.seriesLimitPerTarget int
-     Optional limit on the number of unique time series a single scrape target can expose. See https://docs.victoriametrics.com/victoriametrics/vmagent/#cardinality-limiter for more info
-  -promscrape.streamParse
-     Whether to enable stream parsing for metrics obtained from scrape targets. This may be useful for reducing memory usage when millions of metrics are exposed per each scrape target. It is possible to set 'stream_parse: true' individually per each 'scrape_config' section in '-promscrape.config' for fine-grained control
-  -promscrape.suppressDuplicateScrapeTargetErrors
-     Whether to suppress 'duplicate scrape target' errors; see https://docs.victoriametrics.com/victoriametrics/vmagent/#troubleshooting for details
-  -promscrape.suppressScrapeErrors
-     Whether to suppress scrape errors logging. The last error for each target is always available at '/targets' page even if scrape errors logging is suppressed. See also -promscrape.suppressScrapeErrorsDelay
-  -promscrape.suppressScrapeErrorsDelay duration
-     The delay for suppressing repeated scrape errors logging per each scrape targets. This may be used for reducing the number of log lines related to scrape errors. See also -promscrape.suppressScrapeErrors
-  -promscrape.vultrSDCheckInterval duration
-     Interval for checking for changes in Vultr. This works only if vultr_sd_configs is configured in '-promscrape.config' file. See https://docs.victoriametrics.com/victoriametrics/sd_configs/#vultr_sd_configs for details (default 30s)
-  -promscrape.yandexcloudSDCheckInterval duration
-     Interval for checking for changes in Yandex Cloud API. This works only if yandexcloud_sd_configs is configured in '-promscrape.config' file. See https://docs.victoriametrics.com/victoriametrics/sd_configs/#yandexcloud_sd_configs for details (default 30s)
   -pushmetrics.disableCompression
      Whether to disable request body compression when pushing metrics to every -pushmetrics.url
   -pushmetrics.extraLabel array

      Timezone to use for timestamps in logs. Timezone must be a valid IANA Time Zone. For example: America/New_York, Europe/Berlin, Etc/GMT+3 or Local (default "UTC")
   -loggerWarnsPerSecondLimit int
      Per-second limit on the number of WARN messages. If more than the given number of warns are emitted per second, then the remaining warns are suppressed. Zero values disable the rate limit
-  -maxBackfillAge value
-     The maximum allowed age for the ingested samples with historical timestamps. Samples with timestamps older than now-maxBackfillAge are rejected during data ingestion. By default, or when set to 0, -maxBackfillAge equals to -retentionPeriod, e.g. it is unlimited within the configured retention. This can be useful for limiting ingestion of historical samples, for example, when older data has been moved to another storage tier. See https://docs.victoriametrics.com/victoriametrics/single-server-victoriametrics/#retention
-     The following optional suffixes are supported: s (second), h (hour), d (day), w (week), M (month), y (year). If suffix isn't set, then the duration is counted in months (default 0)
   -maxConcurrentInserts int
      The maximum number of concurrent insert requests. Set higher value when clients send data over slow networks. Default value depends on the number of available CPU cores. It should work fine in most cases since it minimizes resource usage. See also -insert.maxQueueDuration (default 2*cgroup.AvailableCPUs())
