# 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.webp">
## 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/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).

##### VMalert CRD for vmoperator
```console

export MANAGED_VM_URL=https://gw-c15-1c.cloud.victoriametrics.com
export ALERTMANAGER=http://alertmanager:9093
cat << EOF | kubectl apply -f -
apiVersion: operator.victoriametrics.com/v1beta1
kind: VMAlert

```
##### Testing
You can ingest metric that will raise an alert
```console
export TOKEN=81e8226e-****-****-****-*************
export MANAGED_VM_URL=https://gw-c15-1c.cloud.victoriametrics.com/
curl -H "Authorization: Bearer $TOKEN" -X POST "$MANAGED_VM_URLapi/v1/import/prometheus" -d 'up{job="vmalert-test", instance="localhost"} 0'
```
#### Cluster
