# Alerts

Composer Monitor comes pre-built with provisioned alert configurations including two Alerts and a Slack contact point template.

These alerts are shown on the home dashboard.

## Composer instance down
This Alert will trigger if a Composer instance target (as specified in `composerInstances.yml`) is not responding (sending Logs or Metrics) for at least 1 minute.

## Customizing built-in alerts
Feel free to customize the built-in alerts in the `config/alerts` folder. Please refer to the [Grafana Documentation](https://grafana.com/docs/grafana/latest/alerting/set-up/provision-alerting-resources/file-provisioning/){target=`_blank`}.

Remember to restart Composer Monitor after making changes to the provisioned alerting resources.

## Extending Alerts
Feel free to add more Alerts. Keep in mind that the Composer Monitor pre-built Alerts can not be modified via Grafana as they are provisioned via the alerts yaml files. Any additional rules can be created and managed with Grafana - but are only stored locally (if not exported and added to the yaml configuration files).
