[Xymon] Xymon script for linux

[Bruce Ferrell]

I'm curious how you propose actually using sar data in a client message.  On my system /var/log/sa is 44M of text data.

vmstat (procps) is already used and feeds rrd on the server via the client message; which is a MUCH more compact, long term storage format (The rrds for the same system are only 13M).

The perennially discussed issues around parsing iproute2 output are kind of well cpovered so we'll let that be... And no, SUSE hasn't removed net-tools.  It's just not installed in 
a very minimal install.
