    AnalyticDB:Set event alerts

    Last Updated:Mar 30, 2026

    AnalyticDB for MySQL cluster O&M events and resource scaling plans are integrated into CloudMonitor. Configure event-triggered alert rules to receive notifications by email or webhook when cluster events occur — enabling faster detection and response to maintenance events before they affect your workloads.

    Supported events

    CloudMonitor can trigger alerts on the following AnalyticDB for MySQL events:

    Event Trigger condition
    Resource scaling plan delay A resource scaling plan execution is delayed beyond the scheduled time.
    Resource scaling plan failure A resource scaling plan fails to execute.
    Minor version update (scheduled) A minor version update is scheduled and not yet started.
    Minor version update (executing) A minor version update is in progress.
    Minor version update (completed) A minor version update completes successfully.
    Minor version update (canceled) A scheduled minor version update is canceled.
    Subscribe to Minor version update (scheduled) to receive advance notification before an update starts. This gives you time to configure a maintenance window or cancel the update before it runs.
