[Xymon] no vmstat data for 8 hours on weekdays?

[Chris.Morris at rwe.com]

I think Mike said yesterday that is was his "procs" section that was
causing the client to generate oversized client message. This test
precedes the vmstat test in xymonclient-aix.sh

		That did it. I'm not sure if MAXMSG_STATUS or
MAXMSG_DATA is the culprit, though I suspect it's _DATA.


	Nice one.  Pretty sure it would be MAXMSG_CLIENT, which relates
to the client messages.  I have this set to 2048 on my server because I
have some particularly fast-moving log files I want to monitor on a
couple of my servers.

	Rather than increasing the limit, you might want to find out why
the client message is so large and try to reduce the size if you can.
Perhaps the server is logging heeeeaps of messages into a logfile that's
being monitored. Have a browse through the client data and see if
there's one section that's really big and can probably be adjusted or
eliminated.

	$ xymoncmd xymon localhost 'clientlog name-of-client' | less

	If it's log data, and you don't actually report on log messages,
you might consider removing the "log:" entry from client-local.cfg on
the Xymon server - either from the [aix] section, or (if it exist) from
the [name-of-host] section.

	Or you can have the client put a cap on the size of log data
being sent back in its client message by adjusting the "log:" entry in
the file client-local.cfg on the server.  This limit is fetched by the
client from the server after it reports its client data.  So an
adjustment on the server can take up to 10 minutes to be honoured by the
client.  The default for AIX syslog.log is 10k, so it's unlikely that
this alone could push your client messages beyond 512k.
