composer/WARN/2023_008
Product: Cloud Composer Rule class: WARN - Something that is possibly wrong
Description
The Airflow monitoring pod pings the database every minute and reports health status as True if a SQL connection can be established or False if not. Note that the environment health could be intermittently unhealthy due to events like scheduled maintenances. However, overall it should be healthy.
Remediation
To check the health of your database, you can use the following health status metric: composer.googleapis.com/environment/database_health.
Otherwise, you can check if there was a maintenance operation aligned with the unhealthy time frame from the monitoring dashboard. Note that maintenance operations happen during the configured maintenance window. If your current maintenance window does not fit to your business requirements, please consider changing it.
