My Google-fu of the maillist archive is weak and I didn't see anything relevant on Xymonton.
I have a job pool that is restarted weekly via cron if no jobs are running. I would like to be alerted if its process start time is more than 2 weeks ago.
Is there a native way to alert that a process hasn't has been running too long? Sort of like the analysis.cfg "UP" check but for a process.
There's nothing out-of-the-box, but the [ps] section of the client data for many systems shows the "STARTED" column, and could be parsed for the start time of your process, such as in a server-side script that did like so:
$XYMON $XYMSRV "clientlog $HN section=ps"
Example output can be seen here:

Note that not all operating systems have the same "ps" output and so this technique might only work for some servers.
Hmm, my new xymon-procmem utility uses this very technique to alert on memory hogs. It wouldn't take a lot to have it do the same for start time, although parsing different time/date formats could be challenging to do in an OS-agnostic way (that is, so that it can run on all/most POSIX Xymon servers).
