I did setup few Log based alert for K8s POD's log through Query Builder but didn't generate alert then i came to know about this

Note: Presently the logs, traces and exceptions-based alerts support only Clickhouse Query based metric.

Dose that means i have to write ClickHouse query only and can't use Query Builder available into "Create an Alert" section ? is that correct ?

It might be possible that error has not occurred recently. Can you try to generate error again and check?

Also try updating the time period to 24 hrs, does it works?
