-            Queue may overflow due to multiple reasons:
-             1. Some bad rules produce too many series at once. This can be limited using the global `-rule.resultsLimit` flag or `limit` param at the rule group level.

 Please find the changelog for VictoriaMetrics Anomaly Detection below.
 
-## v1.29.2
-Released: 2026-04-02
-
-- UI: Updated [vmanomaly UI](https://docs.victoriametrics.com/anomaly-detection/ui/) from [v1.5.1](https://docs.victoriametrics.com/anomaly-detection/ui/#v151) to [v1.6.0](https://docs.victoriametrics.com/anomaly-detection/ui/#v160), see respective [release notes](https://docs.victoriametrics.com/anomaly-detection/ui/#v160) for details. Notable changes include **full UI state modification** from [AI assistant](https://docs.victoriametrics.com/anomaly-detection/ui/#ai-assistance) and [showing business boundaries](https://docs.victoriametrics.com/anomaly-detection/ui/#visualization-panel) on a graph.
-
-- IMPROVEMENT: Added an option to proxy reader TLS/credential configuration from the `config.reader` to UI, allowing users to leverage the same secure connection settings for both backend and UI queries to datasource without requiring `vmauth` in front of the datasource for UI access. See [authentication section](https://docs.victoriametrics.com/anomaly-detection/ui/#authentication) for details.
-
-- IMPROVEMENT: Added configurable reconnect retry handling for [`VmWriter`](https://docs.victoriametrics.com/anomaly-detection/components/writer/#vm-writer) with `connection_retry_attempts` arg after transient connection-level write failures.

The alert state is stored in a SQL database by default, but [Grafana can be configured to store this data in a Prometheus-compatible database like VictoriaMetrics as well](https://grafana.com/docs/grafana/latest/alerting/set-up/configure-alert-state-history/#configure-prometheus-for-alert-state-grafana_alerts-metric).
-- Datasource-managed: alerts have their rules defined, stored, and evaluated in an external system like vmalert and Alertmanager, with Grafana just providing the UI. State is stored in VictoriaMetrics.
-
-The following table compares the two modes:
-
-| Aspect              | Grafana-Managed                                    | Data Source-Managed           |
-| ------------------- | -------------------------------------------------- | ----------------------------- |
-| Where rules live    | Grafana's SQL database                             | vmalert's YAML config         |
-| Evaluation          | Grafana's scheduler                                | vmalert                       |
-| Horizontal Scaling  | Complex (requires HA SQL database)                 | Simple (add more pods)        |
-| State storage       | SQL backend or a Prometheus datasource             | VictoriaMetrics               |
-| UI Management       | Full create/edit in Grafana                        | View-only                     |
-| Dependencies        | SQL + Grafana                                      | VictoriaMetrics               |
-| Version control     | Complex (rules must be exported/imported)          | Easy (rules are in YAML file) |
-
-## Datasource-managed Alert Topology
-
-The proposed alert setup relies on the following services:
-
-- VictoriaMetrics: provides the time-series database and persists alert status.
-- vmalert: evaluates alerting rules from its config file against VictoriaMetrics data and forwards firing alerts to Alertmanager.
-- Alertmanager: groups and routes alerts to the configured recipients.
-- Grafana: serves as the unified UI, connecting to VictoriaMetrics for rules and metrics, and to Alertmanager for notifications/silences.

-## vmalert Demo with Docker {#docker}
-
-In this section, we'll describe how you can try datasource-managed alerts on Grafana with Docker Compose. Follow the steps in this section to see how the Grafana UI looks in datasource-managed alerts.
-
-First, create `alerts.yml`. The following configuration file creates an always-firing alert, which you can use to test datasource-managed alerts in Grafana.
-
-```yaml
-# alerts.yml
-groups:
-  - name: demo
-    rules:
-      # Always-firing demo alert so you see something immediately
-      - alert: AlwaysFiring
-        expr: vector(1)
-        for: 10s
-        labels:
-          severity: warning
-        annotations:
-          summary: "Demo alert that always fires"
-          description: "This is a demo alert from vmalert using vector(1)."
-
-      # Simple recording rule you can graph in Grafana
-      - record: demo:vector_one
-        expr: vector(1)
-```
-
-Next, create a basic Alertmanager config called `alertmanager.yml`. This example does not forward alerts anywhere, but serves as a source for Grafana:
-
-```yaml
-# alertmanager.yml
-global:
-  resolve_timeout: 5m
-
-route:
-  receiver: "log"
-
-receivers:
-  - name: "log"
-```
-
-Finally, create `grafana-datasources.yml` to configure Grafana to use VictoriaMetrics and Alertmanager as datasources for alerts and notifications:
-
-```yaml
-# grafana-datasources.yml
-apiVersion: 1
-
-datasources:
-  - name: VictoriaMetrics
-    type: prometheus
-    access: proxy
-    url: http://victoriametrics:8428
-    isDefault: true
-
-  - name: Alertmanager
-    type: alertmanager
-    access: proxy
-    url: http://alertmanager:9093
-    jsonData:
-      implementation: prometheus
-```
-
-The final piece is the Docker Compose file. This ties all the services together and sets up the required command-line arguments:
-
-```yaml
-# compose.yml
-services:
-  victoriametrics:
-    image: victoriametrics/victoria-metrics:v1.140.0
-    command:
-      - "--storageDataPath=/victoria-metrics-data"
-      - "--selfScrapeInterval=10s"

-    ports:
-      - "8880:8880"
-    volumes:
-      - ./alerts.yml:/etc/vmalert/alerts.yml:ro
-
-  grafana:

-    volumes:
-      - ./grafana-datasources.yml:/etc/grafana/provisioning/datasources/datasources.yml:ro
-      - grafana-data:/var/lib/grafana
-
-volumes:
-  vm-data:
-  grafana-data:
-```
-
-Let's break down the main command line arguments that connect every component:
-
-- VictoriaMetrics
-  - `-vmalert.proxyURL`: forwards Grafana requests for `/api/v1/rules` and `/api/v1/alerts` to vmalert, enabling rule visibility in Grafana UI
-
-- vmalert
-  - `-datasource.url`: configures VictoriaMetrics as the query source for rule evaluation
-  - `-remoteWrite.url`: defines VictoriaMetrics as the backend used to persist rule state across restarts
-  - `-remoteRead.url`: defines VictoriaMetrics as the backend used to read historical state for pending alerts
-  - `-notifier.url`: directs firing alerts to Alertmanager
-  - `-external.url`: defines the base URL for alert links so users see the public URL of Alertmanager, or an external alerting UI like Karma or Grafana in notifications.
-  - `-external.alert.source`: creates a template for clickable alert links for Grafana. Allows Alertmanager UI to link directly to Grafana
-
-Now, start the demo with:
-
-```sh
-docker compose up -d
-```
-
-Open your browser at `localhost:3000` and log in to Grafana with username `admin` and password `admin`.
-
-If you open the sidebar and select **Alerting** > **Alert rules**, you should be able to see one alert pending or firing.
-
-![Screenshot of Grafana alert pane](grafana-alert-firing.webp)
-<figcaption style="text-align: center; font-style: italic;">Datasource-managed alert firing in Grafana</figcaption>
-
-Open the sidebar again and go to **Alerting** > **Active notifications** to see the active alert reported by Alertmanager.
-
-![Screenshot of Grafana Active notifications Page](grafana-notifications.webp)
-
-You can also see the alerts in VMUI by opening the browser in `http://localhost:8428/vmui/?#/rules`. This is possible only when we have configured `-vmalert.proxyURL` in VictoriaMetrics.
-
-![Screenshot of VMUI](vmui-alerts.webp)
-<figcaption style="text-align: center; font-style: italic;">Alerts can be visualized in VMUI directly</figcaption>
-
-If you open the browser in `http://localhost:9093/#/alerts`, you will see the Alertmanager UI with the firing alert.
-
-![Screenshot of Alertmanager](alertmanager-alerts.webp)
-<figcaption style="text-align: center; font-style: italic;">Alertmanager UI showing the firing alert</figcaption>
-
-Clicking **Source** should take you back to Grafana and display the query that generated the alert.

-## vmalert and VictoriaMetrics Single on Kubernetes {#vmsingle}
-
-This section explains how to configure datasource-managed alerts on the VictoriaMetrics single-node version on Kubernetes.
-
-### Prerequisites
-
-- A Kubernetes cluster
-- VictoriaMetrics single-node
-- Grafana
-- Helm values or config files used for installation
-
-You can follow this guide to install all required components: [Kubernetes monitoring via VictoriaMetrics single](https://docs.victoriametrics.com/guides/k8s-monitoring-via-vm-single/).
-
-### 1. Ensure VictoriaMetrics and Grafana are installed
-
-Ensure you have added and updated the VictoriaMetrics Helm repository:
-
-```sh
-helm repo add vm https://victoriametrics.github.io/helm-charts/
-helm repo update
-
-```
-
-Confirm that the VictoriaMetrics single-node version is installed (assuming the release name `vmsingle` from the [installation guide](https://docs.victoriametrics.com/guides/k8s-monitoring-via-vm-single/))
-
-```sh
-kubectl get pods -l app.kubernetes.io/instance=vmsingle
-```
-
-You should get a single running pod:
-
-```sh
-NAME                                        READY   STATUS    RESTARTS   AGE
-vmsingle-victoria-metrics-single-server-0   1/1     Running   0          48m
-```
-
-Do the same for Grafana:
-
-```sh
-kubectl get pod -l app.kubernetes.io/name=grafana
-```
-
-You should get the name of the Grafana pod running in your cluster:
-
-```sh
-NAME                          READY   STATUS    RESTARTS   AGE
-my-grafana-65d6d4ccbc-nxkxq   1/1     Running   0          58m
-```
-
-### 2. Install vmalert and Alertmanager
-
-Create a Helm values file for vmalert and Alertmanager called `vm-alerting-values.yml`. 
-
-The example below comes with two demo alerts. Add your own vmalert [alerting rules](https://docs.victoriametrics.com/victoriametrics/vmalert/#rules) in the `config: alerts:` section below.
-
-```sh
-cat <<EOF > vm-alerting-values.yml
-# Enable and configure Alertmanager
-alertmanager:
-  enabled: true
-  config:
-    global:
-      resolve_timeout: 5m
-    route:
-      group_by: ["alertname"]
-      group_wait: 30s
-      group_interval: 5m
-      repeat_interval: 12h
-      receiver: "log"
-
-    receivers:
-      - name: "log"
-        # place your default route here for notifications
-
-# Configure vmalert ("server" section in this chart)
-server:
-  # vmalert evaluation datasource: point at vmsingle’s Prometheus-compatible API
-  datasource:
-    url: http://vmsingle-victoria-metrics-single-server.default.svc.cluster.local.:8428
-
-  # Where vmalert stores and reads alert state (remote write/read)
-  remote:
-    write:
-      url: http://vmsingle-victoria-metrics-single-server.default.svc.cluster.local.:8428
-    read:
-      url: http://vmsingle-victoria-metrics-single-server.default.svc.cluster.local.:8428
-
-  # Configure Alertmanager as notifier
-  notifier:
-    alertmanager:
-      # Adjust namespace/name if you install into a non-default namespace or change the release name
-      url: http://vmalert-victoria-metrics-alert-alertmanager:9093
-
-  # Inline demo rules. Add your alerting groups and rules here
-  config:
-    alerts:
-      groups:
-      - name: vm-health
-        rules:
-          - alert: TooManyRestarts
-            expr: changes(process_start_time_seconds{job=~"victoriametrics|vmagent|vmalert"}[15m]) > 2
-            labels:
-              severity: critical
-            annotations:
-              summary: "{{ $labels.job }} too many restarts (instance {{ $labels.instance }})"
-              description: "Job {{ $labels.job }} has restarted more than twice in the last 15 minutes. It might be crashlooping."
-          - alert: ServiceDown
-            expr: up{job=~"victoriametrics|vmagent|vmalert"} == 0
-            for: 2m
-            labels:
-              severity: critical
-            annotations:
-              summary: "Service {{ $labels.job }} is down on {{ $labels.instance }}"
-              description: "{{ $labels.instance }} of job {{ $labels.job }} has been down for more than 2 minutes."
-EOF
-```
-
-Install `vmalert` and Alertmanager with:
-
-```sh
-helm install vmalert vm/victoria-metrics-alert -f vm-alerting-values.yml
-```
-
-### 3. Configure VictoriaMetrics single to proxy to vmalert
-
-For datasource-managed alerts, Grafana talks to VictoriaMetrics, and VictoriaMetrics proxies alerting-related API calls to vmalert via the `-vmalert.proxyURL` flag.
-
-First, check the service name for `vmalert`:
-
-```sh
-kubectl get svc -l app.kubernetes.io/instance=vmalert,app=server
-```
-
-Get the name of the `vmalert` service:
-
-```sh
-NAME                                    TYPE        CLUSTER-IP   EXTERNAL-IP   PORT(S)    AGE
-vmalert-victoria-metrics-alert-server   ClusterIP   None         <none>        8880/TCP   58m
-```
-
-The internal DNS name for this service, in the default namespace, will be:
-
-```text
-vmalert-victoria-metrics-alert-server.default.svc.cluster.local:8880
-```
-
-Next, create a Helm values file with the internal Kubernetes URL for vmalert.
-
-```sh
-cat <<EOF > vm-vmalert-proxy-values.yml
-# vm-vmalert-proxy-values.yaml
-server:
-  extraArgs:
-    vmalert.proxyURL: http://vmalert-victoria-metrics-alert-server.default.svc.cluster.local:8880
-EOF
-
-```
-
-Update the configuration of VictoriaMetrics single by applying both *your original Helm values* and this new overlay. In the example below, the original values file is called `vmsingle-values-file.yml` (this is the file you used when you first installed the cluster):
-
-```sh
-helm upgrade vmsingle vm/victoria-metrics-single \
-  -f vmsingle-values-file.yml \
-  -f vm-vmalert-proxy-values.yml
-```
-
-After this upgrade, vmsingle will start proxying `/api/v1/rules`, `/api/v1/alerts`, and other `vmalert` [endpoints](https://docs.victoriametrics.com/victoriametrics/vmalert/#web) to the vmalert service, enabling Grafana’s alerting UI and API to work through the VictoriaMetrics datasource. 
-
-To finish the setup, jump to the [Configure Grafana](https://docs.victoriametrics.com/guides/vmalert-datasource-managed-alerts-grafana/#grafana) section
-
-## vmalert and VictoriaMetrics Cluster on Kubernetes {#vmcluster}
-
-This section explains how to configure datasource-managed alerts on the VictoriaMetrics cluster version on Kubernetes.
-
-### Prerequisites
-
-- A Kubernetes cluster  
-- VictoriaMetrics cluster
-- Grafana  
-- Helm values or config files used for the installation of the cluster
-
-You can follow this guide to install the cluster and Grafana first: [Kubernetes monitoring with VictoriaMetrics cluster](https://docs.victoriametrics.com/guides/k8s-monitoring-via-vm-cluster/).
-
-### 1. Ensure VictoriaMetrics and Grafana are installed
-
-Ensure you have added and updated the VictoriaMetrics Helm repository:
-
-```sh
-helm repo add vm https://victoriametrics.github.io/helm-charts/
-helm repo update
-```
-
-Confirm that the VictoriaMetrics cluster is installed (assuming the release name `vmcluster` from the [installation guide](https://docs.victoriametrics.com/guides/k8s-monitoring-via-vm-cluster/)):
-
-```sh
-kubectl get pods -l app.kubernetes.io/instance=vmcluster
-```
-
-You should see pods for `vmselect`, `vminsert`, and `vmstorage`, for example:
-
-```text
-NAME                                                           READY   STATUS    RESTARTS   AGE
-vmcluster-victoria-metrics-cluster-vminsert-b4d494b4c-cx2m5    1/1     Running   0          3m8s
-vmcluster-victoria-metrics-cluster-vminsert-b4d494b4c-xdv76    1/1     Running   0          3m8s
-vmcluster-victoria-metrics-cluster-vmselect-67979c98fc-7hfdl   1/1     Running   0          3m8s
-vmcluster-victoria-metrics-cluster-vmselect-67979c98fc-ftpzn   1/1     Running   0          3m8s
-vmcluster-victoria-metrics-cluster-vmstorage-0                 1/1     Running   0          3m8s
-vmcluster-victoria-metrics-cluster-vmstorage-1                 1/1     Running   0          2m48s
-```
-
-VictoriaMetrics exposes its write API via the `vminsert` service on port 8480 and its read (Prometheus-compatible) API via the `vmselect` service on port 8481 by default. For a default installation, these DNS names are:
-
-- Write: `vmcluster-victoria-metrics-cluster-vminsert.default.svc.cluster.local.:8480`  
-- Read: `vmcluster-victoria-metrics-cluster-vmselect.default.svc.cluster.local.:8481`
-
-Now, ensure Grafana is installed:
-
-```sh
-kubectl get pod -l app.kubernetes.io/name=grafana
-```
-
-You should get the name of the Grafana pod running in your cluster:
-
-```sh
-NAME                          READY   STATUS    RESTARTS   AGE
-my-grafana-65d6d4ccbc-nxkxq   1/1     Running   0          58m
-```
-
-### 2. Install vmalert and Alertmanager
-
-Create a Helm values file for vmalert and Alertmanager called `vm-alerting-values.yml`.  
-
-The example below comes with two demo alerts. Add your own vmalert [alerting rules](https://docs.victoriametrics.com/victoriametrics/vmalert/#rules) in the `config: alerts:` section below.
-
-
-```sh

-            annotations:
-              summary: "{{ $labels.job }} too many restarts (instance {{ $labels.instance }})"
-              description: "Job {{ $labels.job }} has restarted more than twice in the last 15 minutes.
-                It might be crashlooping."
-          - alert: ServiceDown

-
-
-The key differences from the [single-node setup](https://docs.victoriametrics.com/guides/vmalert-datasource-managed-alerts-grafana/#vmsingle) section
-- `server.datasource.url` and `server.remote.read.url` point to the `vmselect` read endpoint (`/select/multitenant/prometheus/`).
-- `server.remote.write.url` points to the `vminsert` write endpoint (`/insert/multitenant/prometheus/`).
-
-Install `vmalert` and Alertmanager with:
-
-```sh
-helm install vmalert vm/victoria-metrics-alert -f vm-alerting-values.yml
-```
-
-### 3. Configure VictoriaMetrics Cluster to proxy to vmalert
-
-For datasource-managed alerts, Grafana talks to VictoriaMetrics, and VictoriaMetrics proxies alerting-related API calls to vmalert via the `-vmalert.proxyURL` flag. In the cluster version, set this flag on `vmselect` and point it to the vmalert service so Grafana can reach the alert state.
-
-First, check the service name for vmalert:
-
-```sh
-kubectl get svc -l app.kubernetes.io/instance=vmalert,app=server
-```
-
-You should see something like:
-
-```sh
-NAME                                    TYPE        CLUSTER-IP   EXTERNAL-IP   PORT(S)    AGE
-vmalert-victoria-metrics-alert-server   ClusterIP   None         <none>        8880/TCP   58m
-```
-
-The internal DNS name for this service, in the default namespace, will be:
-
-```text
-vmalert-victoria-metrics-alert-server.default.svc.cluster.local:8880
-```
-
-Create a Helm values overlay file for the cluster called `vmcluster-vmalert-proxy-values.yml`.  
-
-The `vmselect.extraArgs` map in the `victoria-metrics-cluster` chart allows you to pass arbitrary command-line flags to vmselect, including `-vmalert.proxyURL`.
-
-```sh
-cat <<EOF > vmcluster-vmalert-proxy-values.yml
-vmselect:
-  extraArgs:
-    vmalert.proxyURL: http://vmalert-victoria-metrics-alert-server.default.svc.cluster.local:8880
-EOF
-```
-
-Update the VictoriaMetrics cluster configuration by applying both your *original Helm values* and this new overlay. In the example below, the original values file is called `vmcluster-values-file.yml` (this is the file you used when you first installed the cluster):
-
-```sh
-helm upgrade vmcluster vm/victoria-metrics-cluster \
-  -f victoria-metrics-cluster-values.yml \
-  -f vmcluster-vmalert-proxy-values.yml
-```
-
-After this upgrade, vmselect will start proxying `/api/v1/rules`, `/api/v1/alerts`, and other `vmalert` endpoints to the vmalert service, enabling Grafana’s alerting UI and API to work through the VictoriaMetrics datasource.
-
-To finalize the setup, continue on to the next section, [Configure Grafana](#grafana).
-
-## Configure Grafana {#grafana}
-
-The last step on any Kubernetes-based installation is to add Alertmanager to Grafana so that Grafana can show notifications alongside the rules it discovers via the VictoriaMetrics datasource.
-
-Get the service name for Alertmanager in your cluster:
-
-```sh
-kubectl get svc -l app.kubernetes.io/instance=vmalert,app=alertmanager
-```
-
-You should see something like:
-
-```text
-NAME                                          TYPE        CLUSTER-IP      EXTERNAL-IP   PORT(S)    AGE
-vmalert-victoria-metrics-alert-alertmanager   ClusterIP   10.43.114.243   <none>        9093/TCP   68m
-```
-
-Next, add Alertmanager to Grafana:
-
-1. Log in to your Grafana dashboard.  
-2. Go to **Connections** > **Datasources**.  
-3. Press **+ Add new data source**.  
-4. Search and select “Alertmanager”.  
-5. Fill in the following parameters (adjusting namespace/service name if needed):  
-   - Implementation: Prometheus  
-   - URL: `http://vmalert-victoria-metrics-alert-alertmanager.default.svc.cluster.local:9093`  
-
-   Ensure the URL matches the Alertmanager service name you obtained earlier.
-
-6. Press **Save & Test**.

-
-With vmselect’s `vmalert.proxyURL` set and Alertmanager configured as a datasource, Grafana should now be able to display vmalert rules and alert instances from the VictoriaMetrics Cluster datasource and show notifications managed by Alertmanager in its UI.
