[Xymon] Error in parsing of filesystem usage when monitoring NFS mounts

[Marcus Mundt]

Hello J. C.,

xymon client version 4.3.3 on openSUSE 13.1 (i586)

in /home/xymon/client/bin/xymonclient-linux.sh I edited the excludes to get the info on the NFS:
echo "[df]"
#EXCLUDES=`cat /proc/filesystems | grep nodev | awk '{print $2}' | xargs echo | sed -e     's! ! -x !g'`
EXCLUDES="sysfs -x rootfs -x bdev -x proc -x cgroup -x cpuset -x tmpfs -x devtmpfs -x d    ebugfs -x securityfs -x sockfs -x pipefs -x anon_inodefs -x devpts -x ramfs -x hugetlbf    s -x pstore -x mqueue -x autofs -x ncpfs -x binfmt_misc"
#df -Pl -x iso9660 -x $EXCLUDES | sed -e '/^[^  ][^     ]*$/{
# without "l" lists NAS_BACKUP_DAILY
df -hP -x iso9660 -x $EXCLUDES | sed -e '/^[^   ][^     ]*$/{
N
s/[     ]*\n[   ]*/ /
}'

This is the client data reported in the web GUI:
[df] Filesystem Size Used Avail Use% Mounted on 
/dev/sda1 15G 1.7G 12G 13% / 
/dev/sdc1 1.8T 1.3T 468G 74% /WD_BACKUP_WEEKLY 
/dev/sda2 21G 49M 20G 1% /home 
172.X.X.X:/volume1/Backup 26T 17T 9.0T 65% /NAS_BACKUP_DAILY 
/dev/sdb1 1.8T 962G 780G 56% /WD_BACKUP_MONTHLY

Xymon Server Version: 4.3.0-0.20101114.beta3

Thanks for any help! Found a similar entry in the Mailing List from 2008, but there is no solution provided as far as I can see.

All the best from Berlin,
