This plugin checks the amount of used disk space on a mounted file system

and generates an alert if free space is less than one of the threshold values

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 paths. 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 paths. 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 100 -c 50 -C -w 1000 -c 500 -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 100 -c 50 -C -w 1000 -c 500 -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
