Uffda, yew ask a tooff kvestion!
Short answer is Performance Tools, PEX (Performance Explorer), and iDoctor.
There's really no short way into this - you need to get friendly with the
Performance Tools manual.
A great site is the Performance Management Resource Library
<
http://www-1.ibm.com/servers/eserver/iseries/perfmgmt/resource.htm>. There
is a link there to the various iDoctor pieces, too. One of these is called
Job Watcher. Pricing for iDoctor is tough, IMO, but when you need it, you
need it. The PEX Analyzer is $6000 for a 1-year contract, last I heard.
(P05, but I don't know if it's tier priced.) But the presentation is GUI -
actually very nice stuff.
There's an article, "Collecting and Analyzing PEX Trace Profile Data", that
is about profiling an application, which is the final tool you might use.
IBM recommends using the Perf Tools first, to isolate things, then go down
to PEX, but you already may want the deeper stuff.
Another article is "Measuring Performance of Application Transactions",
about putting some instrumentation in your application and collecting what
you want. Part of the article talks about identifying bottlenecks. The app
has to be yours - not a vendor's product, unless you have the source, as
well - I think.
There are also things in Ops Nav now - you might want to check out the
Redbooks on "Managing you iSeries with Operations Navigator"
