Export Check Rules

Build check rules visually in Dash0, then export them as YAML for version control and deployment.

Once you have created check rules as defined in About Creating Check Rules, do the following:

  1. Click Alerting in the left navigation menu and select Checks from the submenu or click Check Rules here to go directly to the Check Rules list.

  2. Select a check rule and click YAML in the navigation bar at the top.

    Export check rule

Export Format

The exported YAML follows the Prometheus PrometheusRule format, extended with Dash0-specific annotations (dash0-threshold-critical, dash0-threshold-degraded, and dash0-enabled):
