-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/) | ✅ | ✅ | ✅ |
-| [vmrestore](https://docs.victoriametrics.com/victoriametrics/vmrestore/) | ✅ | ✅ | ✅ |

-| [vmalert](https://docs.victoriametrics.com/victoriametrics/vmalert/) |  ✅ | ✅ | ❌ |
-
-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` |

-There are two ways to get started with VictoriaMetrics:
-
-* [Try it locally](https://docs.victoriametrics.com/victoriametrics/quick-start/#try-it-locally) - if you just want to see how VictoriaMetrics works,
-  go with the single binary: download it, start it with one command, and see live metrics
-  in the built-in UI in a couple of minutes. No Docker, no configuration files
-  and no extra components are required;
-* [Install it](https://docs.victoriametrics.com/victoriametrics/quick-start/#how-to-install) - if you want to set up VictoriaMetrics for real use,
-  pick a distribution (single-node, cluster or cloud) and an installation method
-  (Docker, Helm, binary releases, etc.).
-
-If you'd rather not install anything at all, try [Playgrounds](https://docs.victoriametrics.com/playgrounds/) -
-a list of publicly available playgrounds for VictoriaMetrics software.
-
-Whichever way you choose, you may also find interesting the other sections of this page,

-and [productionization](https://docs.victoriametrics.com/victoriametrics/quick-start/#productionization)
-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
-2026-07-10T16:55:06.615Z    info    app/victoria-metrics/main.go:102    started VictoriaMetrics in 0.019 seconds
-...
-2026-07-10T16:55:06.615Z    info    lib/httpserver/httpserver.go:148    started server at http://0.0.0.0:8428/
-```
-
-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.

-via [DNS A records](https://datatracker.ietf.org/doc/html/rfc1035#section-3.4.1). The port from the original URL is appended to each discovered IP address.

-When a `dns+` URL uses the `https` scheme, `vmagent` connects to the discovered
-IP addresses directly. This affects [TLS](https://en.wikipedia.org/wiki/Transport_Layer_Security)
-in two ways:
-
-* No [SNI](https://en.wikipedia.org/wiki/Server_Name_Indication) is sent in the TLS handshake,
-  since the connection target is an IP address rather than a hostname.
-* The server certificate is verified against the IP address, so the verification fails
-  unless the certificate contains the corresponding
-  [IP SAN](https://en.wikipedia.org/wiki/Subject_Alternative_Name) entries.
-
-To use `dns+` URLs with HTTPS, pass the original hostname via the `-remoteWrite.tlsServerName`
-command-line flag. It is used both as SNI and as the name the server certificate
-is verified against:
