From hobbitclient-sunos.sh you can see that Xymon uses following
commands to report disk usage
...
echo "[df]"
ROOTFSTYPE=`/bin/df -n / | awk '{print $3}'`
/bin/df -F $ROOTFSTYPE -k
# Then see what fs types are in use, and weed out those we dont want.
FSTYPES=`/bin/df -n -l|cut -d: -f2 | awk '{print $1}'|egrep -v
"^${ROOTFSTYPE}|^proc|^fd|^mntfs|^ctfs|^devfs|^objfs|^nfs|^lofs|^sharefs"|sort|uniq`

set $FSTYPES
while test "$1" != ""; do
  /bin/df -F $1 -k | egrep -v " /var/run" | tail +2
  shift
done
...

This means that /var/run, /dev/fd, /system/object, /etc/mnttab,
/system/contract, /proc and /dev mounts are excluded from the output.
/var and /common seem to be lofs mounts and will be excluded as well.



On your solaris zones how do you monitor your filesysteme.
The problem that I have with df on the global zone is that hobbit
does not have read access to this var partition.
Therefore it is not monitored to on the global zone.

How do you proceed to monitor your disk spaces on your solaris zones?
I am thinking of patching this script.
Is there a better solution?
We use the sparse-root model for all of our Solaris servers running zones and do not have any issue like this. 

Example from a server running 6 zones besides the global:

$ df -k
