I have a Cisco ACS appliance that runs a CentOS-based OS.  I cannot

just send them to the Xymon server and have it magically know what to do

If you modify the data you have to that the command outputs have the
headers that Xymon expects - the "[df]", "[ps]" etc section markers, see
the "client data" from one of your other servers - then there is a fair
chance that it might work.

In other words, if you can make your data look like what e.g. a Linux
client would send, then it should work with Xymon.
Yup, I was already going down that route while parsing the output from the
Cisco ACS command.

The way to send the data off to Xymon would then be

   xymon 10.0.0.1 "@" < datafile

and your datafile would have to begin with a line

   client myhostname.linux cisco_acs

The "linux" part means that it will be interpreted by the Linux client
handler; "cisco_acs" defines the configuration "class" that you can
optionally use in the analysis.cfg to write common rules for all of your
ACS systems.

The worst that can happen is that you won't see any statuses on your Xymon
webpage; then we'll have to dig into the xymond/client/linux.c code to see
how it is interpreted.
Wow, this worked perfectly!  I can see the columns on the webpage now.
Thanks, Henrik!
