Looking for mainframe DB2 monitoring tool, mainly for comparison between existing DB2 and SQL scenario and similar on other platforms, but main thing here is to measure and pinpoint problem areas on the zOS DB2 and SQL.
Any recommendations?

DB2PM seems to have been replaced by DB2PE, or even Omegamon XE for DB2, perhaps someone could clarify what is available nowadays?
Compuware's Strobe appears quite comprehensive too.
Real-time monitoring not absolutely necessary, but ability to post-process and report on SMF records or similar would be highly desirable.
The objective I guess is to be able to compare current and past performance, and specifically to monitor and report on SQL calls and any hot-spots that need investigating.

Thanks in advance, guys and gals!
