check-mount 1.1.0

Description:

checkmount 1.1.0

About
check_mount is a Nagios/Icinga plugin for checking for the presence of
mounted filesystems.
Sometimes, it is only important to monitor the presence of a mount, and not
the amount of free (or used) storage on that filesystem. For example, when
monitoring NFS clients it may be redundant to use check_disk to monitor
the NFS mounts because the amount of free storage on those mounts is monitored
elsewhere. Additionally, check_disk can give a false negative if the
filesystem is not mounted at all, but the directory used as a mount point is
present.


Usage
usage: check_mount [-h] [-w RANGE] [-c RANGE] [-p PATH] [-t TYPE] [-M PATH]
[-v]

optional arguments:
-h, --help show this help message and exit
-w RANGE, --warning RANGE
Generate warning state if number of mounts is outside
this range
-c RANGE, --critical RANGE
Generate critical state if number of mounts is
outside this range
-p PATH, --path PATH A mount point to check to ensure it is present. May
be specified more than once. This option is
incompatible with --type.
-t TYPE, --type TYPE Only check mounts of a particular type. If specified
more than once, the count of present mounts will
include all mounts of all types specified. This
option is incompatible with --path.
-M PATH, --mount-path PATH
Override the path to mount(8) [Default: /sbin/mount]
-v, --verbose Increase output verbosity (use up to 3 times).

Counting Mounts
If you’re only concerned with making sure the correct number of mounts are
present, you can set a warning/critical range.
To warn if anything other than exactly 5 filesystems are mounted:
check_mount -w 5:5
To retun critical if fewer than 5 filesystems are mounted, and a warning if
more than 5 are mounted:
check_mount -w :5 -c 5:


Checking Mounts by Type
If you’re only concerned with a particular type of mount, for example you want
to ensure that all of your network mounts are present, but ignore any others,
you can supply a list of filesystem types to check_mount.
To look only at AFS and NFS mounts, and to expect exactly 2 total mounts (one
of each):
check_mount -t NFS -t AFS -w 2:2
By default, check_mount ignores several filessytem pseudo-types. Ignoring
these can be overridden by specifying them, along with any other types you
would like to check, on the command line. Filesystem types ignored by default
are:
autofs bpf cgroup cgroup2 debugfs
devpts devtmpfs hugetlbfs mqueue proc
pstore securityfs sysfs tmpfs


Checking Specific Mount Points
If you wish to check specific mount points you can specify one or more on the
command line with the –path argument:
check_mount -p /home -w1:1
Unlike other modes of operation, when checking specific mount points
check_mount applies the warning and critical ranges to each individual
mount, rather than the sum of all mounts. This allows check_mount to
include the names of specific mounts in its error message. So, if you’re
checking three different mount points this way, and you want to return a
critical alert if any of them are missing, you would use a command like this:
check_mount -p /home -p /var -p /opt -c1:1
