make scrape_series_added negative when the number of series decreased

This commit adds a rpc retry by dialing a new connection instead of
getting an old one from the connection pool when the previous rpc error
is `io.EOF`.

It helps prevent broken connections from remaining for too long and
causing failed requests and partial responses during `vmstorage` rolling
restart period

 Please find the changelog for VictoriaMetrics Anomaly Detection below.
 
+## v1.29.0
+Released: 2026-03-05
+
+- UI: Updated [vmanomaly UI](https://docs.victoriametrics.com/anomaly-detection/ui/) from [v1.4.3](https://docs.victoriametrics.com/anomaly-detection/ui/#v143) to [v1.5.0](https://docs.victoriametrics.com/anomaly-detection/ui/#v150), see respective [release notes](https://docs.victoriametrics.com/anomaly-detection/ui/#v150) for details. Notable changes include [AI assistance](https://docs.victoriametrics.com/anomaly-detection/ui/#ai-assistance) support capable of applying model configuration changes, generating VMAlert rules, and providing general guidance on using the product.
+
+- IMPROVEMENT: Optimized internal data structures for readers when `query_from_last_seen_timestamp` [parameter](https://docs.victoriametrics.com/anomaly-detection/components/reader/#config-parameters) is enabled, resulting in reduced memory usage and improved performance for large datasets.
+
+- IMPROVEMENT: Hardened [hot reload](https://docs.victoriametrics.com/anomaly-detection/components/#hot-reload) with staged snapshot apply and automatic rollback.

 ## Preventing alert fatigue
 Produced anomaly scores are designed in such a way that values from 0.0 to 1.0 indicate non-anomalous data, while a value greater than 1.0 is generally classified as an anomaly. However, there are no perfect models for anomaly detection, that's why reasonable defaults expressions like `anomaly_score > 1` may not work 100% of the time. However, anomaly scores, produced by `vmanomaly` are written back as metrics to VictoriaMetrics, where tools like [`vmalert`](https://docs.victoriametrics.com/victoriametrics/vmalert/) can use [MetricsQL](https://docs.victoriametrics.com/victoriametrics/metricsql/) expressions to fine-tune alerting thresholds and conditions, balancing between avoiding [false negatives](https://victoriametrics.com/blog/victoriametrics-anomaly-detection-handbook-chapter-1/#false-negative) and reducing [false positives](https://victoriametrics.com/blog/victoriametrics-anomaly-detection-handbook-chapter-1/#false-positive).

+## AI Assistance
+
+{{% available_from "v1.29.0" anomaly %}} Copilot is an AI assistant built into the vmanomaly UI. It understands current anomaly detection configuration in the UI and helps iterate faster and obtain better results - without leaving the UI, searching the docs manually, or being an expert in anomaly detection.
+
+### What you can do with Copilot
+
+- **Ask questions** about any model (e.g. [Prophet](https://docs.victoriametrics.com/anomaly-detection/components/models/#prophet) or [Z-score](https://docs.victoriametrics.com/anomaly-detection/components/models/#online-z-score) — parameters, trade-offs, when to use each)
+- **Improve detection quality** — describe what's wrong ("too many false positives", "missing spikes") and Copilot reads the config, searches the docs, and proposes a validated configuration change to fix the issue.
+- **Get config suggestions inline** — suggestions appear as interactive cards with an explanation and a YAML diff; click **Apply** to write the change directly to your current settings, or **Decline** to keep the conversation going.
+
+### How it works
+
+Copilot appears as a **chat popup** anchored to the bottom-right corner of the page. The panel is resizable by dragging its left edge, and can be opened or closed by clicking the respective icon.
+
+> [!TIP] Copilot is context-aware
+> It reads your active model, scheduler, and anomaly settings from the UI automatically, so you don't need to paste your config manually.
+
+### Configuration
+
+AI Assistant is disabled by default; enable it with `VMANOMALY_COPILOT_ENABLED=true`, then configure an LLM provider API key and, optionally, a model. Once enabled and configured, Copilot will appear as a chat popup in the bottom-right corner of the UI.
+
+
+
+Supported providers and model formats:
+
+- **Anthropic** — set `ANTHROPIC_API_KEY`; model format: `anthropic:<model>`
+  - Examples: `claude-haiku-4-5`, `claude-sonnet-4-6`; see [full list](https://platform.claude.com/docs/en/about-claude/models/overview#latest-models-comparison)
+- **OpenAI** — set `OPENAI_API_KEY`; model format: `openai:<model>`
+  - Examples: `gpt-5-mini`, `gpt-5.2`; see [full list](https://platform.openai.com/docs/models)
+
+Set exactly one provider key matching your selected model provider:
+
+```bash
+# Anthropic
+export ANTHROPIC_API_KEY=your_key_here
+
+# or OpenAI
+export OPENAI_API_KEY=your_key_here
+```
+
+Optionally override the default model:
+
+```bash
+export VMANOMALY_COPILOT_MODEL=openai:gpt-5-mini
+```
+
+### MCP tools server
+
+Connects Copilot to [mcp-vmanomaly](https://github.com/VictoriaMetrics/mcp-vmanomaly) for full tool access (built-in docs, models configuration and validation, alerts recommendation, service healthchecks, etc.). Full [tools list](https://github.com/VictoriaMetrics/mcp-vmanomaly?tab=readme-ov-file#toolset):
+
+> [!NOTE]
+> Only `http` [mode](https://github.com/VictoriaMetrics/mcp-vmanomaly?tab=readme-ov-file#modes) is supported. Set `VMANOMALY_MCP_SERVER_URL` to the MCP server HTTP endpoint. The server must be reachable from within the vmanomaly container.
+
+For example:
+
+```bash
+export VMANOMALY_MCP_SERVER_URL=http://localhost:8081/mcp
+```
+
+Use `localhost` only when the vmanomaly process can reach the MCP server on its own loopback interface (for example, both running on the host). If vmanomaly runs in a separate Docker container, use a reachable container or host address instead.
+
+**Example**: if using Docker, run `mcp-vmanomaly` and vmanomaly UI in the same Docker network so they can reach each other by container name:
+
+```bash
+docker network create vmanomaly-network

+Using [Grafana](https://grafana.com/) with [vmauth](https://docs.victoriametrics.com/victoriametrics/vmauth/) is an effective way to provide [multi-tenant](https://docs.victoriametrics.com/victoriametrics/cluster-victoriametrics/#multitenancy) access to your metrics, logs, and traces.
+vmauth provides a way to authenticate users using [JWT tokens](https://en.wikipedia.org/wiki/JSON_Web_Token) {{% available_from "v1.138.0" %}} issued by an external identity provider.
+Those tokens can include information about the user and their tenant, which vmauth can use to restrict access so users only see metrics in their own tenant.
+
+This guide walks through configuring Grafana with OIDC to query metrics from both single-node and cluster deployments of VictoriaMetrics.
+
+## Prerequisites
+
+* [Docker](https://docs.docker.com/engine/install/) and [docker compose](https://docs.docker.com/compose/) must be installed.
+* [jq tool](https://jqlang.org/)
+* Add `grafana` and `keycloak` hosts to the `/etc/hosts` file, pointing to `127.0.0.1`.
+
+```
+# /etc/hosts
+
+# Setup vmauth - Multi-Tenant Access with Grafana & OIDC
+# https://docs.victoriametrics.com/guides/grafana-vmauth-openid-configuration/#prerequisites
+127.0.0.1 keycloak grafana
+```
+
+## Identity provider
+
+The identity provider must be able to issue JWT tokens with the following `vm_access` claim:
+
+```json
+{
+  "exp": 1772019469,
+  "vm_access": {
+    "metrics_account_id": 0,
+    "metrics_project_id": 0,
+    "metrics_extra_labels": [
+      "team=dev"
+    ],
+    "metrics_extra_filters": [
+     "{env=~\"aws|gcp\",cluster!=\"production\"}"
+    ]
+  }
+}
+```
+> Note: all properties inside `vm_access` are optional and could be omitted. `vm_access: {}` is a valid claim value.
+
+Some identity providers support only string-based claim values, and vmauth supports these as well:
+```json
+{
+  "exp": 1772019469,
+  "vm_access": "{\"metrics_account_id\": 0, \"metrics_project_id\": 0}"
+}
+```
+
+See details about all supported options in the [vmauth - JWT token auth proxy](https://docs.victoriametrics.com/victoriametrics/vmauth/#jwt-token-auth-proxy).
+
+### Setup Keycloak
+
+[Keycloak](https://www.keycloak.org/) is an open-source identity provider that can issue JWT tokens.
+
+Add the following section to your `compose.yaml` file to configure Keycloak:
+
+```yaml
+# compose.yaml
+services:
+  keycloak:
+    image: quay.io/keycloak/keycloak:26.3
+    command:
+      - start-dev
+      - --http-port=3001
+    ports:
+      - 127.0.0.1:3001:3001
+    environment:
+      KC_HOSTNAME_BACKCHANNEL_DYNAMIC: "true"
+      KC_HOSTNAME: http://keycloak:3001/
+      KC_BOOTSTRAP_ADMIN_USERNAME: admin
+      KC_BOOTSTRAP_ADMIN_PASSWORD: change_me
+    volumes:
+      - keycloakdata:/opt/keycloak/data
+
+volumes:
+  keycloakdata: {}
+```
+
+Start the services:
+```sh
+docker compose up
+```
+
+Once Keycloak is available, follow the steps below to configure the OIDC client and users for Grafana:
+
+### Create client
+
+1. Open [http://keycloak:3001](http://keycloak:3001).
+1. Log in with credentials.
+    - Username: `admin`
+    - Password: `change_me`
+1. Go to `Clients` -> `Create client`.
+    - Use `OpenID Connect` as `Client Type`.
+    - Specify `grafana` as `Client ID`.
+    - Click `Next`.
+   ![Create client 1](create-client-1.webp)
+1. Enable `Client authentication`
+    - Enable `Authorization`.
+    - Enable `Direct access grants` (this is only required for testing the token but it can be disabled in production)
+   ![Create client 2](create-client-2.webp)
+    - Click `Next`.
+1. Add the Grafana URL as `Root URL`. For example, `http://grafana:3000`.
+   ![Create client 3](create-client-3.webp)
+    - Click `Save`.
+1. Go to `Clients` -> `grafana` -> `Client scopes`.
+   ![Create mapper 1](create-mapper-1.webp)
+   - Click on `grafana-dedicated` -> `Configure a new mapper` -> `User attribute`.
+   ![Create mapper 2](create-mapper-2.webp)
+1. Configure the mapper as follows:
+   - Set `Name` to `vm_access`.
+   - Set `User Attribute` to `vm_access`.
+   - Set `Token Claim Name` to `vm_access`.
+   - Set `Claim JSON Type` to `JSON`.
+   - Enable `Add to ID token` and `Add to access token`.
+   
+   ![Create mapper 3](create-mapper-3.webp)
+   - Click `Save`.
+
+### Create users
+
+1. Go to `Realm settings` -> `User profile`.
+   - Click `Create attribute`.
+   - Specify `vm_access` as `Attribute [Name]`.
+   ![User attributes](create-attribute.webp)
+   - Click `Create`.
+1. Go to `Users` -> `Add user`.
+   - Mark email as verified.
+   - Specify `test-dev` as `Username`.
+   - Specify `test-dev@example.com` as `Email`.
+   - Specify `vm_access` as `{"metrics_account_id": 1, "metrics_project_id": 2, "metrics_extra_labels": ["team=dev"]}`.
+   - Press `Create`
+   ![User attributes](user-attributes.webp)
+   - Go to `Users` -> `test-dev` user -> `Credentials` tab.
+   - Press `Set Password`.
+   - Type the password `testpass`.
+   - Disable `Temporary` option 
+   - Press `Save` and confirm.
+
+1. Go to `Users` -> `admin` user.
+   - Mark email as verified.
+   - Specify `admin@example.com` as `Email`.
+   - Specify `vm_access` as `{"metrics_account_id": 1, "metrics_project_id": 2, "metrics_extra_labels": ["team=admin"]}`.
+   - Click `Save`.
+
+### Test identity provider
+
+Gather the following information needed to configure Grafana:
+
+1. The Realm name must be `master`. To get the name, go to `Realm settings` -> `General` and copy the `Name`.
+1. The Client ID must be `grafana`. To get the ID, go to `Clients` -> `grafana` -> `Settings` and copy the `Client ID`.
+1. The Client Secret is dynamically generated. To get the secret, go to `Clients` -> `grafana` -> `Credentials` and copy the `Client Secret`.<br>
+   ![Client secret](client-secret.webp)
+   <br>
+
+Test that everything is working by requesting a token using `curl`:
+
+```sh
+TOKEN=$(curl --fail -s -X POST "http://keycloak:3001/realms/master/protocol/openid-connect/token" \
+    -H "Content-Type: application/x-www-form-urlencoded" \
+    -d "client_id=grafana" \
+    -d "client_secret={CLIENT_SECRET}" \
+    -d "grant_type=password" \
+    -d "username=test-dev" \
+    -d "password=testpass" | jq -r '.access_token') && echo $TOKEN
+```
+
+<!--
+fish example:
+set TOKEN (curl --fail -s -X POST "http://keycloak:3001/realms/master/protocol/openid-connect/token" \
+  -H "Content-Type: application/x-www-form-urlencoded" \
+  -d "client_id=grafana" \
+  -d "client_secret={CLIENT_SECRET}" \
+  -d "grant_type=password" \
+  -d "username=test-dev" \
+  -d "password=testpass" | jq -r '.access_token'); and echo $TOKEN
+-->
+
+The response should contain a valid JWT token with the `vm_access` claim. 
+Use [jwt.io](https://jwt.io/) to decode and verify that the vm_access claim is present with the expected values.
+
+> Please note that the issued token is short-lived, so you might need to refresh it before use in later chapters. 
+
+## VictoriaMetrics
+
+### Storage and scraping
+
+First, create a `scrape.yaml` file with vmagent scrape configuration to ingest data into vmsingle and vmstorage for testing purposes:
+
+```yaml
+# scrape.yaml
+scrape_configs:
+  - job_name: stat
+    metric_relabel_configs:
+      # The team label showcases extra_filter functionality used with vmsingle.
+      - if: "{instance =~ 'vmauth.*'}"
+        action: replace
+        target_label: team
+        replacement: admin
+      - if: "{instance =~ 'vmagent.*'}"
+        action: replace
+        target_label: team
+        replacement: dev
+
+      # The vm_account_id and vm_project_id labels showcase tenant functionality used with vmcluster
+      - if: "{instance =~ 'vmauth.*'}"
+        action: replace
+        target_label: vm_account_id
+        replacement: '1'
+      - if: "{instance =~ 'vmauth.*'}"
+        action: replace
+        target_label: vm_project_id
+        replacement: '2'
+      - if: "{instance =~ 'vmagent.*'}"
+        action: replace
+        target_label: vm_account_id
+        replacement: '1'
+      - if: "{instance =~ 'vmagent.*'}"
+        action: replace
+        target_label: vm_project_id
+        replacement: '2'
+    static_configs:
+      - targets:
+          - vmagent:8429
+          - vmauth:8427
+
+```
+
+Add VictoriaMetrics single-node and cluster to the `compose.yaml` file.
+These services will be used to store metrics scraped by vmagent and to query them via Grafana using vmauth.
+
+Relabeling rules will add the `team` label to the scraped metrics in order to test multi-tenant access.
+Metrics from `vmagent` will be labeled with `team=dev` and metrics from `vmauth` will be labeled with `team=admin`.
+
+vmagent will write data into VictoriaMetrics single-node and cluster (with tenant `1:2`).
+
+```yaml
+# compose.yaml
+services:
+  vmsingle:
+    image: victoriametrics/victoria-metrics:v1.138.0
+
+  vmstorage:
+    image: victoriametrics/vmstorage:v1.138.0-cluster
+
+  vminsert:
+    image: victoriametrics/vminsert:v1.138.0-cluster
+    command:
+      - -storageNode=vmstorage:8400
+
+  vmselect:
+    image: victoriametrics/vmselect:v1.138.0-cluster
+    command:
+      - -storageNode=vmstorage:8401
+
+  vmagent:
+    image: victoriametrics/vmagent:v1.138.0
+    volumes:
+      - ./scrape.yaml:/etc/vmagent/config.yaml
+    command:
+      - -promscrape.config=/etc/vmagent/config.yaml
+      - -remoteWrite.url=http://vminsert:8480/insert/multitenant/prometheus/api/v1/write
+      - -remoteWrite.url=http://vmsingle:8428/api/v1/write
+```
+
+### Vmauth
+
+Before we start, let's explore the concept of placeholders supported in the vmauth configuration.
+Placeholders can be used inside the `url_prefix` property to restrict access by setting the [tenant](https://docs.victoriametrics.com/victoriametrics/cluster-victoriametrics/#url-format) or [extra filters](https://docs.victoriametrics.com/victoriametrics/single-server-victoriametrics/#prometheus-querying-api-enhancements).
+
+A placeholder value is taken from the authenticated JWT token.
+The following placeholders are supported:
+- `{{.MetricsTenant}}` placeholder is a combination of `vm_access.metrics_account_id` and `vm_access.metrics_project_id` delimited by `:`.
+- `{{.MetricsExtraLabels}}` placeholder is substituted from `vm_access.metrics_extra_labels` claim property.
+- `{{.MetricsExtraFilters}}` placeholder is substituted from `vm_access.metrics_extra_filters` claim property.
+
+Now, let's create a vmauth configuration file `auth.yaml` that enables OIDC authorization using the [identity provider](https://docs.victoriametrics.com/guides/grafana-vmauth-openid-configuration/#identity-provider).
+For cluster access, we use the `{{.MetricsTenant}}` placeholder to route requests to a specific tenant.
+For single-node access, we use `{{.MetricsExtraLabels}}`. 
+Read more about templating in vmauth [docs](https://docs.victoriametrics.com/victoriametrics/vmauth/#jwt-claim-based-request-templating).
+
+```yaml
+# auth.yaml
+users:
+  - jwt:
+      oidc:
+        issuer: 'http://keycloak:3001/realms/master'
+    url_map:
+      - src_paths:
+          - "/insert/.*"
+        drop_src_path_prefix_parts: 1
+        url_prefix: "http://vminsert:8480/insert/{{.MetricsTenant}}/prometheus/"
+      - src_paths:
+          - "/select/.*"
+        drop_src_path_prefix_parts: 1
+        url_prefix: "http://vmselect:8481/select/{{.MetricsTenant}}/prometheus/"
+      - src_paths:
+          - "/single/.*"
+        drop_src_path_prefix_parts: 1
+        url_prefix: "http://vmsingle:8428?extra_label={{.MetricsExtraLabels}}"
+```
+
+Now add the vmauth service to `compose.yaml`:
+
+```yaml
+# compose.yaml
+services:
+  vmauth:
+    image: docker.io/victoriametrics/vmauth:v1.138.0
+    ports:
+      - 8427:8427
+    volumes:
+      - ./auth.yaml:/auth.yaml
+    command:
+      - -auth.config=/auth.yaml
+```
+
+### Test vmauth
+
+Start the services:
+
+```sh
+docker compose up
+```
+
+Use the token obtained in the [Test identity provider](https://docs.victoriametrics.com/guides/grafana-vmauth-openid-configuration/#test-identity-provider) section to test vmauth configuration.
+
+Cluster select:
+```sh
+curl --fail http://localhost:8427/select/api/v1/status/buildinfo -H "Authorization: Bearer $TOKEN"
+
+# Output:
+# {"status":"success","data":{"version":"2.24.0"}}
+```
+
+Cluster insert:
+```sh
+curl --fail http://localhost:8427/insert/api/v1/write -H "Authorization: Bearer $TOKEN" -i
+# Output
+# HTTP/1.1 204 No Content
+# ...
+```
+
+Single select:

+curl --fail http://localhost:8427/single/api/v1/status/buildinfo -H "Authorization: Bearer $TOKEN"
+
+# Output:

+```
+
+## Grafana
+
+### Setup
+
+Add the Grafana service to the `compose.yaml` file.
+This configuration enables OAuth authentication using the previously configured Keycloak service as the identity provider.
+Don't forget to replace the `{CLIENT_SECRET}` placeholder with the actual client secret gathered earlier.
+
+```yaml

+
+Alternatively, OAuth authentication can be enabled via the `grafana.ini` configuration file.
+Don't forget to mount it to the Grafana service at `/etc/grafana/grafana.ini`.
+
+```ini
+# grafana.ini
+
+[server]
+root_url = http://grafana:3000
+
+[auth.generic_oauth]

+api_url = http://keycloak:3001/realms/master/protocol/openid-connect/userinfo
+use_refresh_token = true
+```
+
+After starting Grafana with the new config, you should be able to log in [http://grafana:3000](http://grafana:3000) using your [identity provider](https://docs.victoriametrics.com/guides/grafana-vmauth-openid-configuration/#identity-provider).
+
+![Grafana login](grafana-login.webp)
+
+### Datasource
+
+Create two Prometheus datasources in Grafana with the following URLs: `http://vmauth:8427/select` and `http://vmauth:8427/single`, pointing to the `vmselect` and `vmsingle` services, respectively. Make sure the authentication method is set to `Forward OAuth identity`.
+
+![Prometheus datasource](grafana-datasource-prometheus.webp)
+
+You can also use the VictoriaMetrics [Grafana datasource](https://github.com/VictoriaMetrics/victoriametrics-datasource) plugin.
+See installation instructions in [Grafana datasource - Installation](https://docs.victoriametrics.com/victoriametrics/victoriametrics-datasource/#installation).
+
+Users with the `vm_access` claim will be able to query metrics from the specified tenant with extra filters applied.
+
+### Test access
+
+The Grafana datasources configuration should be as follows:
+
+![Test datasources](grafana-test-datasources.webp)
+<figcaption style="text-align: center; font-style: italic;">Grafana vmauth datasources</figcaption>
+
+Let's log in as a dev user in the VictoriaMetrics cluster and single versions.
+Both data sources should return the same metrics.
+
+The only difference is the filter: for the VictoriaMetrics cluster, the `vmauth-cluster` data source must restrict results by `tenant=1:2`.

+## Summary
+
+In this guide, we demonstrated how to set up vmauth with OIDC authorization using Keycloak as the identity provider. We also showed how to provide multi-tenant access to your metrics stored in VictoriaMetrics, single-node or cluster, using Grafana and vmauth with OIDC authorization enabled.

+Using [vmagent](https://docs.victoriametrics.com/victoriametrics/vmagent/) with [vmauth](https://docs.victoriametrics.com/victoriametrics/vmauth/) and OAuth authentication{{% available_from "v1.138.0" %}} enables secure metric ingestion in multi-tenant environments, where vmagent authenticates to vmauth using [JWT tokens](https://en.wikipedia.org/wiki/JSON_Web_Token) issued by an external identity provider. These tokens include tenant information so that metrics are written to the correct tenant.
+
+This guide walks through configuring vmagent to ingest metrics through vmauth with OIDC authorization enabled.
+
+## Prerequisites
+
+* [Docker](https://docs.docker.com/engine/install/) and [docker compose](https://docs.docker.com/compose/) must be installed.
+* [jq tool](https://jqlang.org/)
+* Add the `keycloak` host to the `/etc/hosts` file pointing to `127.0.0.1`.
+
+```
+# /etc/hosts
+
+# Setup vmagent - Multi-Tenant remote write & OIDC
+# https://docs.victoriametrics.com/guides/vmagent-openid-configuration/#prerequisites
+127.0.0.1 keycloak
+```
+
+## Identity provider
+
+The identity service must be able to issue JWT tokens with the following `vm_access` claim:
+
+```json
+{
+  "exp": 1772019469,
+  "vm_access": {
+    "metrics_account_id": 0,
+    "metrics_project_id": 0
+  }
+}
+```
+> Note: if `metrics_account_id` or `metrics_project_id` are not specified, the default value `0` is used.
+
+Some identity providers only support string-based claim values; vmauth supports those as well:
+```json
+{
+   "exp": 1772019469,
+   "vm_access": "{\"metrics_account_id\": 0, \"metrics_project_id\": 0}"
+}
+```
+
+See details about all supported options in the [vmauth documentation](https://docs.victoriametrics.com/victoriametrics/vmauth/#jwt-token-auth-proxy).
+
+### Setup Keycloak
+
+[Keycloak](https://www.keycloak.org/) is an open-source identity service that can issue JWT tokens.
+
+Add the following section to your `compose.yaml` file to configure Keycloak:
+
+```yaml
+# compose.yaml
+services:
+  keycloak:
+    image: quay.io/keycloak/keycloak:26.3
+    command:
+      - start-dev
+      - --http-port=3001
+    ports:
+      - 127.0.0.1:3001:3001
+    environment:
+      KC_HOSTNAME_BACKCHANNEL_DYNAMIC: "true"
+      KC_HOSTNAME: http://keycloak:3001/
+      KC_BOOTSTRAP_ADMIN_USERNAME: admin
+      KC_BOOTSTRAP_ADMIN_PASSWORD: change_me
+    volumes:
+      - keycloakdata:/opt/keycloak/data
+
+volumes:
+  keycloakdata: {}
+```
+
+Run `docker compose up` to start Keycloak.
+
+Once Keycloak is available at `http://keycloak:3001`, follow the steps below to configure the OIDC client for vmagent:
+
+### Create client
+
+1. Log in with admin credentials to your Keycloak instance
+  - Username: `admin`
+  - Password: `change_me`
+1. Go to `Clients` -> `Create client`.
+   - Use `OpenID Connect` as `Client Type`.
+   - Specify `vmagent` as `Client ID`.
+   - Click `Next`.
+   ![Create client 1](vmagent-create-client-1.webp)

+1. Go to `Clients` -> `vmagent` -> `Credentials`.
+   ![Client secret](vmagent-client-secret.webp)

+   ![Create mapper 2](vmagent-create-mapper-2.webp)
+1. Configure the mapper as follows:
+    - `Name` as `vm_access`.
+    - `User Attribute` as `vm_access`.
+    - `Token Claim Name` as `vm_access`.
+    - `Claim JSON Type` as `JSON`.
+    - Enable `Add to ID token` and `Add to access token`.
+
+   ![Create mapper 3](vmagent-create-mapper-3.webp)
+   - Click `Save`.
+
+### Create User Attributes
+
+1. Go to `Realm settings` -> `User profile`.
+   - Click `Create attribute`.
+   - Specify `vm_access` as `Attribute [Name]`.
+   ![User attributes](create-attribute.webp)
+   - Click `Create`.
+
+### Configure service account
+
+1. Go to `Client` -> `vmagent` -> `Service account roles` -> click on `service-account-vmagent`.
+   ![vmagent service account](vmagent-sa.webp)

+   ![User attributes](vmagent-sa-attributes.webp)
+   - Click `Save`.
+
+### Test identity provider
+
+Start the service:
+```sh
+docker compose up
+```
+
+Verify the setup by requesting a token with `curl`:
+
+```sh
+TOKEN=$(curl -s -X POST "http://keycloak:3001/realms/master/protocol/openid-connect/token" \
+  -H "Content-Type: application/x-www-form-urlencoded" \
+  -d "client_id=vmagent" \
+  -d "client_secret={CLIENT_SECRET}" \
+  -d "grant_type=client_credentials" \
+  | jq -r '.access_token') && echo "$TOKEN"
+```
+
+The response should contain a valid JWT token with the `vm_access` claim.
+Use [jwt.io](https://jwt.io/) to decode and inspect the token.
+
+## VictoriaMetrics
+
+### Setup storage
+
+Add the VictoriaMetrics cluster components to the `compose.yaml` file.
+These services will store and query the metrics scraped by vmagent.
+
+```yaml
+# compose.yaml
+services:
+  vmstorage:
+    image: victoriametrics/vmstorage:v1.138.0-cluster
+
+  vminsert:
+    image: victoriametrics/vminsert:v1.138.0-cluster
+    command:
+      - -storageNode=vmstorage:8400
+
+  vmselect:
+    image: victoriametrics/vmselect:v1.138.0-cluster
+    command:
+      - -storageNode=vmstorage:8401
+    ports:
+      - 8481:8481
+```
+
+### Setup vmauth
+
+Create a vmauth configuration file `vm-auth.yaml` that enables OIDC authorization using the identity provider.
+
+The `{{.MetricsTenant}}` is expanded by vmauth into `accountID:projectID` derived from the vm_access claim, and defaults to `0:0` if not set.
+
+```yaml
+# vm-auth.yaml
+
+users:
+- jwt:
+    oidc:
+      issuer: 'http://keycloak:3001/realms/master'
+  url_map:
+    - src_paths:
+        - "/insert/.*"
+      drop_src_path_prefix_parts: 1
+      url_prefix: "http://vminsert:8480/insert/{{.MetricsTenant}}/prometheus/"
+```
+
+Add the vmauth service to `compose.yaml`:
+
+```yaml
+# compose.yaml
+services:
+  vmauth:
+    image: victoriametrics/vmauth:v1.138.0-enterprise
+    ports:
+      - 8427:8427
+    volumes:
+      - ./vm-auth.yaml:/etc/config.yaml
+    command:
+      - -auth.config=/etc/config.yaml
+```
+
+### Test vmauth
+
+Start the services:
+
+```sh
+docker compose up
+```
+
+Use the token obtained in the [Test identity provider](https://docs.victoriametrics.com/guides/vmagent-openid-configuration/#test-identity-provider) section to test the vmauth configuration.
+
+```sh
+curl http://localhost:8427/insert/api/v1/write -H "Authorization: Bearer ${TOKEN}" -i
+# Output
+# HTTP/1.1 204 No Content
+# ...
+```
+
+## Vmagent
+
+### Setup
+
+First, create a demo `scrape.yaml` file with basic scrape targets:
+
+```yaml
+# scrape.yaml
+scrape_configs:
+  - job_name: stat
+    static_configs:
+      - targets:
+          - vmagent:8429
+          - vmauth:8427
+```
+
+Now we'll configure vmagent to authenticate to vmauth using OAuth2 client credentials flow.
+The vmagent service automatically obtains and refreshes JWT tokens from the identity provider and includes them in the `Authorization` header when sending metrics to vmauth.
+This enables secure metric ingestion with proper tenant isolation based on the claims in the JWT token.
+
+We'll use the `vmagent` client that was created in the [Create client](https://docs.victoriametrics.com/guides/vmagent-openid-configuration/#create-client) section.
+The client secret obtained from that step will be used to authenticate vmagent with Keycloak.
+
+Add the vmagent service to `compose.yaml` with OAuth2 configuration:

+
+Go to `http://localhost:8481/select/0/vmui/` and query the `vm_app_version` metric. If the metric is present, then everything is working as expected.
+
+## Summary
+
+This guide showed how to configure vmagent to ingest metrics into a VictoriaMetrics cluster through vmauth using OIDC authentication.
+Vmagent uses the OAuth2 client credentials flow to obtain JWT tokens from Keycloak, which vmauth validates and uses to route requests to the correct tenant.

+The v1.122.x line will be supported for at least 12 months since [v1.122.0](https://docs.victoriametrics.com/victoriametrics/changelog/#v11220) release**
+
+* SECURITY: upgrade Go builder from Go1.24.13 to Go1.25.8. See [the list of issues addressed in Go1.25.8](https://github.com/golang/go/issues?q=milestone%3AGo1.25.8+label%3ACherryPickApproved).
+
+* FEATURE: [MetricsQL](https://docs.victoriametrics.com/victoriametrics/metricsql/): add [histogram_fraction](https://docs.victoriametrics.com/victoriametrics/metricsql/#histogram_fraction) function to calculate the fraction of buckets falling between lowerLe and upperLe. See [#5346](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/5346).
+
+* BUGFIX: all VictoriaMetrics components: replace `histogram` with `untyped` metric metadata type for [VictoriaMetrics histograms](https://docs.victoriametrics.com/victoriametrics/keyconcepts/#histogram) when `-metrics.exposeMetadata` is set. See [#82](https://github.com/VictoriaMetrics/metrics/issues/82).
+* BUGFIX: [vmauth](https://docs.victoriametrics.com/victoriametrics/vmauth/): properly route requests to `default_url`. Previously, `request_path` query arg could be set incorrectly during concurrent requests. See [#10626](https://github.com/VictoriaMetrics/VictoriaMetrics/pull/10626).
+* BUGFIX: [vmagent](https://docs.victoriametrics.com/victoriametrics/vmagent/), [vmsingle](https://docs.victoriametrics.com/victoriametrics/single-server-victoriametrics/), `vminsert` and `vmstorage` in [VictoriaMetrics cluster](https://docs.victoriametrics.com/victoriametrics/cluster-victoriametrics/): properly attach `host` label to the time series ingested via [/datadog/api/beta/sketches](https://docs.victoriametrics.com/victoriametrics/integrations/datadog/#) API. See [#10557](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/10557).
+* BUGFIX: [vmui](https://docs.victoriametrics.com/victoriametrics/single-server-victoriametrics/#vmui): use `increase_pure` instead of `rate` for histogram heatmaps in Explore Metrics to correctly display the first observation in each new bucket. See [#10365](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/10365). Thanks to @ab0utbla-k for the contribution.
+* BUGFIX: `vmstorage` in [VictoriaMetrics cluster](https://docs.victoriametrics.com/victoriametrics/cluster-victoriametrics/): fix inaccurate `vm_filestream_write_duration_seconds_total` due to duplicate counting . After the fix, `vm_filestream_write_duration_seconds_total` will track the duration spent on calling the `write(2)` system call properly.
