Have the alerts been deleted in Grafana? Try restarting Grafana after deleting them.

Do the alerts in Grafana need to be deleted separately?

The alert is for a task that has already been deleted and is delayed.

Logically, it shouldn’t be necessary. Once it’s deleted, it’s gone. I haven’t encountered this issue.

After restarting CDC, the alert has disappeared, but the changefeed still exists in the Grafana monitoring panel.

Changefeed should be operable within PD.
