[Xymon] Xymon, external script question

[Phil Crooker]

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.
