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

|
|
|
|
## Preconditions
|
|
|
|
* [vmalert](https://docs.victoriametrics.com/vmalert/) is installed. You can obtain it by building it from [source](https://docs.victoriametrics.com/vmalert/#quickstart), downloading it from the [GitHub releases page](https://github.com/VictoriaMetrics/VictoriaMetrics/releases/latest), 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-deployment) 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#deployment-access).
