SV: [xymon] Xymon reports excessive memory usage on 1 SLES 11 host

[Carl Melgaard]

Hi,

"free" just gives the normal output, but sometimes it apparently reports bogus data on 1 host. Shrug. And it's the same version running across all the hosts. Thanks for looking into it tho.

Regards,

Carl Melgaard

That looks like output from the 'free' command.  Try going to the server and entering

     free

and see what it says.  Xymon doesn't alter the output at all, it just passes on whatever comes out.  Here's the relevant part of xymonclient-linux.sh, with context:

     echo "[mount]"
     mount
     echo "[free]"
     free
     echo "[ifconfig]"
     /sbin/ifconfig

Here are two separate [free] sections (from history), that resulted in red alerts:

- two different days.

Im actually running 4.4.0-1 on the server, as I was bold when I implemented Xymon originally.
