<p class="MsoNormal"><span style="font-size:10.0pt;font-family:Consolas;color:#1F497D">I created a server-side extension that gets the “ps” information from the client data (already available), parses it, etc. I thought I was set, but it turns out that ps reports
the percentage of CPU utilization over the lifetime of the process. This makes it useless for monitoring CPU utilization by long-running processes, because the data becomes flat.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:10.0pt;font-family:Consolas;color:#1F497D">on the client side, then sending over the output (using the client/local mechanism). Then, my server-side program (which I had already written) obtains the information from
the server using a “xymon clientlog” call, and parses it. (If I didn’t have the server-side part already written, I probably would have run it entirely on the client side, for simplicity.) I also use “NCV” to generate a graph on the server.
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:Consolas;color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:Consolas;color:#1F497D">The information obtained this way is the percentage of CPU utilization by the top processes during the time interval sampled (1 minute, since I’m running “sleep 60”). It
parallels much better what one can get, for example from “topas”. If this were Linux, I might have used “top” instead of “tprof”, but AIX’s version (“topas”) is for interactive use only. And “tprof” allows me to vary the length of the sampling interval. I
have a feeling that 60 seconds is too much; 30 or 15 should be enough.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:Consolas;color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:10.0pt;font-family:Consolas;color:#1F497D">This seems to be working. I’ll know better after a few days. The graph is a very valuable tool for validating this kind of stuff.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:10.0pt;font-family:Consolas">It would be nice to be able to monitor also on CPU utilization. E.g.: “process db2sysc taking more than 90% of the CPU”<o:p></o:p></span></p>
