Thanks Rob and Barton. I'm betting that I can attribute this then to the process "t" which is started by cron often. It seems to grow bit by bit until the next recycle and then starts over. It's being phased out, so I'm not going to sweat it :)

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.... >Date: Mon, 28 Aug 2006 18:20:07 -0500 >Reply-To: Linux on 390 Port <[email protected]> >From: Marcy Cortes <[EMAIL PROTECTED]> > >It's consistently 6 and 7% of an IFL on 1 http server.
