[Xymon] custom graphs

[Root, Paul T]

Yes, I'm working on that now.  I pretty quickly came to the realization that the single RRD file wasn't going to work.

Hi,

                I've had a script that pulls the %mem of certain processes on various machines.  Right now, I have 3 separate groups of machines with different processes being watched. The purpose is to track memory leaks.

                Previously, I had the script just put out a ps -eo 'pid,%mem,cmd' for the desired processes. Then others wanted a graph, so I've reformatted the output to be just a keyword (either the process name or a significant field of the arguments of the command).

                I get something that looks like this now:
Process Memory Usage


SA: 6.5
MBIM: 2.4
OI: 4.1

You might consider using the devmon-way of reporting data in stead of NCV. It has the advantage that you can report data to be entered in multiple RRD's. In Devmon one RRD per interface is use, in your case one RRD per group of machines could be used. The devmon format has also the advantage that colons or equal-signs in the message will not confuse the extractor of the RRD data.

Regards,
  Wim Nelis.
