Lost a measurement after migration to PostgreSQL

I have a rate measurement called GC Impact, PP duration / PP duration w/o Suspension. 

This was working fine when on the Derby DB, migrated to PostgreSQL today and the measurement is no longer working. Both of the measurements within the rate are working (i.e. they plot on a graph) but the rate doesn't.

Ideas? Where to look?

Anything in your dynatrace server log?

Nothing that looks immediately obvious, there is a lot of Missing ConnectionPoolData - but would that cause a measure not to work?

Maybe I should open a ticket in this one?

thats probably the best option

We resolved this by disconnecting and reconnecting to the db - even tho it said connected (we noticed that there was no monitoring data over an hour being displayed too)

thanks for the update.

Just for anybody else out there that sees this post. If you only see data for the last hour it means that we only keep measures in the server memory but dont store any data to the perf warehouse.
