The totals is a sum of all processes - the ESALNXP report shows
processes above the threshold of .1%.  So quite possibly, there
are many http servers or java servers using less than .1%.  You
would NOT want a report that showed all the processes.

The other report is the ESALNXA report. This report shows
CPU by application. So, for example in this report, all the processes
started by process 17860 or 15625 (the parents that spawned these
httpd servers) would be accumulated and reportedcu - but a lot of
that doesn't show up when you just look at processes using more
than .1%.

There is soon also to be a ESALNXU report that shows useage by
logon userid - in answer to many requests.

To further Rob's response. Any process that dies during an
interval has their current interval CPU added to their parent.
If the parent happens to be init, then "init" cpu grows in the
"children".  This shows up here.  For example, cron starts up,
uses some CPU, stops.  This cpu gets allocated to init children.
Applications don't usually have this scenario.

I expect capture ratio currently of processes to be real close
to 100%.  I expect the '*totals' to be very accurate as well.  Rob
and others have been providing pathalogical cases to test this -
and still rarely find a way to show room for improvement....
