Hi Taylor,
I'm new at xymon and am also looking at using the client data.
I found the xymon command itself lets you query current status:
/usr/local/xymon/server/bin/xymon 127.0.0.1 "xymondlog
hostname.domain.com.memory"
hostname.domain.com|memory|green||1301551188|1302151594|1302153394|0|0|10.10.10.1|-1|||Y| green Thu Apr 7 14:46:28 EST 2011 - Memory OK Memory Used Total Percentage &green Physical 9905M 11881M 83% &green Actual 514M 11881M 4% &green Swap 0M 10239M 0%
The above was run on the xymon server, hence the localhost address. It appears to display the current service status page (on the webserver) in text. So it would be pretty easy to parse out the physical memory and compare that with a value you set in the script itself.
cheers.

maintenance that requires shutdown/reboot that occasionally (seldom) on restart one or more of the memory modules in a given host isn't detected.
Sometimes it requires reseating the memory, sometimes just a reboot,
sometimes the memory is bad. Thus we have a need to write a script that will check the amount of memory each host sees, and send an email/alert if its below a given amount.
So I thought why not make use of xymon and the memory test you get for free. A large percentage of our hosts >60% have exactly 6 GB of memory, but a large percentage does not. So I was wondering if there is a way to make use of the hobbit-clients.cfg script where I could set alert thresholds for a new external script.
The default value for any host would be alert if less than 6.0 GB of memory is detected, but I could set custom alerts for given hosts that have more or less than this amount.
I don't believe its possible to use hobbit-client.cfg file in this way, but wanted to check with the list and hope I'm wrong.
Thanks, Taylor
