Severe Incident occurred: Performance Warehouse

Triggered by Performance Warehouse related events.
Exception: An element does not exist perhaps the schema is corrupted

I am getting this alert for every 5 mins(from Dynatrace Self Monitoring Incidents) . Can anyone tell what does it mean.
How to resolve it

Thank you so much in advance.

Hi Karthi,

there should be a more detailed message in the Repository.0.0.log file (see System Information dashlet). It means that either our automatic pwh migration hasn't worked as expected or that the initial set-up wasn't completed correctly or that something broke in the pwh. The detailed message should give us a shot at determining what exactly the reason is.

If you don't mind losing historical measurement data (PPs won't be affected), you could go to Server Settings -> Performance Warehouse -> Rebuild Schema, which should fix the issue.

If this doesn't fix the issue, you probably need more permissions for the database user.

Best regards,

Peter

Hi Peter,

This may be true . Because the PWH got recently VM cloned or migrated.Again migrating the old PWH will solve the issue?

Because I am not sure about loosing the historical data while rebuild schema.

Thanks

Hard to say without detailed logs. Please try the migration again. If it continues to fail and you can't read any detailed information from the Repository.0.0.log file then please open a support ticket and attach a support archive. Thanks,

best regards,

Peter
