check_disk ERR

[amit]

Hello all

i am running the command these commands on a sles9 :
when i run the command like this: /usr/local/nagios/libexec/check_disk -w 10% -c 5% -p /data --> all OK

but when i run it like this: /usr/local/nagios/libexec/check_disk -w 10% -c 5% -p /data/test

i get this : DISK CRITICAL - free space:| [/data/test not found]

i am root on that server and
when i check ls -la on both of the files
they are both configured with the same privileges 755(drwxr-xr-x) and both under owner = root and group = root

please help

thank you all

Here's the full doc on the plugin usage for check disk:

Code: Select all

Usage: check_disk -w limit -c limit [-W limit] [-K limit] {-p path | -x device}
[-C] [-E] [-e] [-g group ] [-k] [-l] [-M] [-m] [-R path ] [-r path ]
[-t timeout] [-u unit] [-v] [-X type]

Options:
 -h, --help
    Print detailed help screen
 -V, --version
    Print version information
 -w, --warning=INTEGER
    Exit with WARNING status if less than INTEGER units of disk are free
 -w, --warning=PERCENT%
    Exit with WARNING status if less than PERCENT of disk space is free
 -c, --critical=INTEGER
    Exit with CRITICAL status if less than INTEGER units of disk are free
 -c, --critical=PERCENT%
    Exit with CRITCAL status if less than PERCENT of disk space is free
 -W, --iwarning=PERCENT%
    Exit with WARNING status if less than PERCENT of inode space is free
 -K, --icritical=PERCENT%
    Exit with CRITICAL status if less than PERCENT of inode space is free
 -p, --path=PATH, --partition=PARTITION
    Path or partition (may be repeated)
 -x, --exclude_device=PATH <STRING>
    Ignore device (only works if -p unspecified)
 -C, --clear
    Clear thresholds
 -E, --exact-match
    For paths or partitions specified with -p, only check for exact paths
 -e, --errors-only
    Display only devices/mountpoints with errors
 -g, --group=NAME
    Group pathes. Thresholds apply to (free-)space of all partitions together
 -k, --kilobytes
    Same as '--units kB'
 -l, --local
    Only check local filesystems
 -L, --stat-remote-fs
    Only check local filesystems against thresholds. Yet call stat on remote filesystems
    to test if they are accessible (e.g. to detect Stale NFS Handles)
 -M, --mountpoint
    Display the mountpoint instead of the partition
 -m, --megabytes
    Same as '--units MB'
 -A, --all
    Explicitly select all pathes. This is equivalent to -R '.*'
 -R, --eregi-path=PATH, --eregi-partition=PARTITION
    Case insensitive regular expression for path/partition (may be repeated)
 -r, --ereg-path=PATH, --ereg-partition=PARTITION
    Regular expression for path or partition (may be repeated)
 -I, --ignore-eregi-path=PATH, --ignore-eregi-partition=PARTITION
    Regular expression to ignore selected path/partition (case insensitive) (may be repeated)
 -i, --ignore-ereg-path=PATH, --ignore-ereg-partition=PARTITION
    Regular expression to ignore selected path or partition (may be repeated)
 -t, --timeout=INTEGER
    Seconds before connection times out (default: 10)
 -u, --units=STRING
    Choose bytes, kB, MB, GB, TB (default: MB)
 -v, --verbose
    Show details for command-line debugging (Nagios may truncate output)
 -X, --exclude-type=TYPE
    Ignore all filesystems of indicated type (may be repeated)

Examples:
 check_disk -w 10% -c 5% -p /tmp -p /var -C -w 100000 -c 50000 -p /
    Checks /tmp and /var at 10% and 5%, and / at 100MB and 50MB
 check_disk -w 100M -c 50M -C -w 1000M -c 500M -g sidDATA -r '^/oracle/SID/data.*$'
    Checks all filesystems not matching -r at 100M and 50M. The fs matching the -r regex
    are grouped which means the freespace thresholds are applied to all disks together
 check_disk -w 100M -c 50M -C -w 1000M -c 500M -p /foo -C -w 5% -c 3% -p /bar
    Checks /foo for 1000M/500M and /bar for 5/3%. All remaining volumes use 100M/50M

I would try experimenting with some of the different flags to see if you can the results you're looking for.

What is the output of df -k? Is /data a filesystem and /data/test a filesystem too?

[tonyyarusso]

To elaborate on niebais' point, I'm not sure check_disk will take any old path and traverse up to find its mount point. Rather, it may only accept paths that are mount points for a filesystem, so unless /data/test is a separate filesystem from /data, you would want to just use /data as the argument. The output of 'df' and 'mount' will help clarify this point.
