    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] [-f] [-g group ] [-k] [-l] [-M] [-m] [-R path ] [-r path ]
    [-t timeout] [-u unit] [-v] [-X type] [-N type] [-n]

    Options:
     -h, --help
        Print detailed help screen
     -V, --version
        Print version information
     --extra-opts=[section][@file]
        Read options from an ini file. See
        https://www.nagios-plugins.org/doc/extra-opts.html
        for usage and examples.
     -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 CRITICAL 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
        Mount point or block device as emitted by the mount(8) command (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
     -f, --freespace-ignore-reserved
        Don't account root-reserved blocks into freespace in perfdata
     -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 plugin 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)
     -N, --include-type=TYPE
        Check only filesystems of indicated type (may be repeated)
     -n, --newlines
        Multi-line output of each disk's status information on a new line

    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
