In its Oracle incarnation, DPA contains various views of wait event / perf data, i,e, per "Users", "Programs", "Machine", "Sessions" and alike, but one important aspect is missing: it would be nice to be able to view wait / perf data per database service, as this is increasingly popular and necessary in Oracle DB installations (Grid Infrastructure, RAC, DataGuard, access management and isolation). Even Oracle AWR reports contain the wait info per "service" summary.
For instance, we are isolating our application access so that each one has a dedicated service name in a database to connect to. Seeing a wait / perf stats and comparison between all registered services would be a major useful information.
I suppose integrating and adding this info in DPA via an additional TAB in various screens would only be a minor product change, because the underlying information is already present (and certainly captured) in v$session and various related internal Oracle views.
