Missing partition in disk monitoring on Solaris 10
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1
Hello,
On a server running solaris 10, df gives:
df -k
Filesystem size used avail capacity Mounted on / 0K 6.7G 38G 15% / /common 123G 1.6M 123G 1% /common /dev 45G 6.7G 38G 15% /dev /var 8.9G 1.8G 7.2G 20% /var proc 0K 0K 0K 0% /proc ctfs 0K 0K 0K 0% /system/contract mnttab 0K 0K 0K 0% /etc/mnttab objfs 0K 0K 0K 0% /system/object swap 17G 328K 17G 1% /etc/svc/volatile fd 0K 0K 0K 0% /dev/fd swap 17G 32K 17G 1% /tmp swap 17G 32K 17G 1% /var/run
Unfortunately hobbit just shows: Filesystem kbytes used avail capacity Mounted on swap 17718392 328 17718064 1% /etc/svc/volatile swap 17718088 32 17718056 1% /tmp / 0 7029995 39920877 15% /
Would you know why not all partitions are monitored?
If no, could you please provide me a hint on how to diagnose this problem?
Thanks in advance for your answer. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org

What your are showing us is not the output of df -k but rather df -h.

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 Filesystem kbytes used avail capacity Mounted on /dev/md/dsk/d0 91499930 10685571 79899360 12% / /devices 0 0 0 0% /devices ctfs 0 0 0 0% /system/contract proc 0 0 0 0% /proc mnttab 0 0 0 0% /etc/mnttab swap 49238864 1440 49237424 1% /etc/svc/volatile objfs 0 0 0 0% /system/object sharefs 0 0 0 0% /etc/dfs/sharetab /platform/sun4u-us3/lib/libc_psr/libc_psr_hwcap2.so.1 91499930 10685571 79899360 12% /platform/sun4u-us3/lib/libc_psr.so.1 /platform/sun4u-us3/lib/sparcv9/libc_psr/libc_psr_hwcap2.so.1 91499930 10685571 79899360 12% /platform/sun4u-us3/lib/sparcv9/libc_psr.so.1 fd 0 0 0 0% /dev/fd swap 4194304 32 4194272 1% /tmp swap 49237512 88 49237424 1% /var/run poolcpasd/root 30707712 2767296 20456153 12% /zones/arescpasd poolcpasp/root 30707712 2770120 20548811 12% /zones/arescpasp poolcpast/root 30707712 2770576 20547973 12% /zones/arescpast pooldev/root 108380160 911553 69755353 2% /zones/aresdev poolprd/root 146571264 819624 69509723 2% /zones/aresprd pooltst/root 146571264 815058 75230859 2% /zones/arestst
Xymon displays:

Shouldn't the first column be in the /dev/dsk/cwtxdysz format or an equivalent thereof (volume manager mount points)?
The output of "df" seems weird. That is probably why xymon did not display them.
Regards.
