A reader asked an interesting question yesterday with regards to the previous post on the subject: where did you get your service metrics from when you queried v$servicemetric-PDB or CDB$ROOT?
I queried the PDB, but this morning repeated the test to make sure the results are consistent, and they are. This is definitely something you’d hope for: you should not have different results in the same v$-view depending on the container you execute your query in for a given CON_ID.
During testing I noticed something interesting though. I queried gv$servicemetric but did not limit the result to the service I wanted to test with (FCFSRV). Here is the query against gv$servicemetric while the system was idle.
