AW: Enterprise Manager Performance Pages Sampling interval

Thanks.

So, the "Average Active Sessions" page comes from v$active_session_history?

At which vertex interval is the graph build on? I don't think that they use every 1 second sample as an vertex.

The performance page wait values comes from v$system_event and not ASH samples. The top activity page comes from v$active_session_history so it's based on the 1 second samples.

Active Sessions are sampled every 1 second and put into v$active_session_history

One of 10 samples goes to dba_hist_active_sess_history

The sampling interval on the EM Performance Pages is ???
