problem witth wait-event "On CPU"

[didmicang]

Hi
in my pg_profile report I have :
Wait event type | Wait event | Waited (s) | %Total
N/A | On CPU | 4944.09 | 97.5

Does this mean that the database is waiting for CPU resources and that this could be causing performance issues?
In reality, database performance is pretty good. Is this wait event credible?

Thanks in advance
Didier

Hi
On CPU means your queries are processing on the CPU. In fact they are should be there, i.e. they are not waiting for any locks or IO.

Ok thank for the answer.
So "On CPU" is a "normal" wait event it's not a problem.
Is it possible to get the list of wait events to monitor in a pg_profile report?
