xymon netapp vfiler quota monitoring

since we moved our nfs-servers from standalone AIX to netapp, we need a separate monitoring

I wrote this script, it runs on the xymon server, and appears as a server test

you need to change the (v)filers etc/host.equiv file, to allow rsh access from your xymon server
If that's a problem, this script may run from any system, where the bb client binary is available for.

alot of the code ist just for nice xymon formatting, it can easily be optimized for performance, without using temp files

#!/usr/bin/ksh                                                        
#Daffi 2009                                                           
#Script reads quota report from a netapp vfiler over rsh              
#change vfilers host.equiv, and add the ipaddress from the rsh client, xymon server in most cases
