# Alerting with vmalert and Managed VictoriaMetrics

This guide explains the different ways in which you can use vmalert in conjunction with Managed VictoriaMetrics

<img src="alerting-vmalert-managed-victoria-metrics-setup.png">

## Preconditions 

* [vmalert](https://docs.victoriametrics.com/vmalert.html) is installed. You can obtain it by building it from [source](https://docs.victoriametrics.com/vmalert.html#quickstart), downloading it from the [GitHub releases page](https://github.com/VictoriaMetrics/VictoriaMetrics/releases), or using the [docker image](https://hub.docker.com/r/victoriametrics/vmalert) for the container ecosystem (such as docker, k8s, etc.).
* [Alertmanager](https://prometheus.io/docs/alerting/latest/alertmanager/) is installed.
* You have a [single or cluster](https://docs.victoriametrics.com/managed-victoriametrics/quickstart.html#creating-instance) deployment in [Managed VictoriaMetrics](https://docs.victoriametrics.com/managed-victoriametrics/overview.html).
* If you are using helm, add the [VictoriaMetrics helm chart](https://github.com/VictoriaMetrics/helm-charts/tree/master/charts/victoria-metrics-alert#how-to-install) repository to your helm repositories. This step is optional.
* If you are using [vmoperator](https://docs.victoriametrics.com/operator/quick-start.html#quick-start), make sure that it and its CRDs are installed. This step is also optional.

## Setup

### Alerting and recording rules file(s)

You need to prepare file(s) with alerting or recording rules.

An example file with one alerting rule. 

alerts.yml

```yaml
groups:
  - name: common
    rules:
    - alert: instanceIsDown
      for: 1m
      expr: up == 0
      labels:
        severity: critical
      annotations:
        summary: "{{ $labels.job }} instance: {{$labels.instance }} is not up"
        description: "Job {{ $labels.job }}  instance: {{$labels.instance }} is not up for the last 1 minute"
```

### Managed VictoriaMetrics access token and deployment endpoint

To use vmalert with Managed VictoriaMetrics, you must create a read/write token, or use an existing one. The token must have write access to ingest recording rules, ALERTS and ALERTS_FOR_STATE metrics, and read access for rules evaluation.

For instructions on how to create tokens, please refer to this section of the [documentation](https://docs.victoriametrics.com/managed-victoriametrics/quickstart.html#access).
