Check Netbackup Media Volume Pool Size

Description:
Simple shell script to check how many tapes are in media volume pool. You may set thresholds to have warning and critical notifications.


Usage: check_tape_pool -p|--pool media_pool_name [-l lower_threshold -u upper_threshold] [-r] [-v] [-h]

Check how many tapes are in media volume pool you specify

Options:
-p or --pool media_pool_name, media volume pool to check
-u or --upper upper_threshold
-l or --lower lower_threshold
-r or --reverse, to reverse notification alert
-v or --version, to display version
-h or --help, to display this help

- option -p media_pool_name is mandatory
- without thresholds, plugin returns number of tapes in media pool without sending notification
- with thresholds, plugin notifies in following way:
-- plugin returns warning if counted tapes in media_pool_name are between lower_threshold and upper_threshold
-- plugin returns a critical if counted tapes in media_pool_name are below lower_threshold (default)
-- with -r option, plugin returns a critical if counted tapes in media_pool_name are above upper_threshold

Useful for:
- monitoring when a volume pool is media oversizing
- monitoring when scratch pool is media undersizing
- monitoring number of tapes in a volume pool for statistics

Plugin provides performance data output for parsing and for graphical use.
Tested under RHEL, written using bash, good for linux.

If running as nagios user - supposed nrpe - you need to configure sudo environment for using netbackup commands defined inside the plugin, i.e.
- edit /etc/sudoers, running visudo

- insert the following under "# Defaults specification" section
# enabling nrpe user to execute sudo commands without a TTY
Defaults:nrpe !requiretty


- insert the following at end of file insert
# enabling nrpe user to run netbackup commands needed
nrpe ALL=(root) NOPASSWD: /usr/openv/volmgr/bin/vmquery
nrpe ALL=(root) NOPASSWD: /usr/openv/volmgr/bin/vmpool


Examples:

[root@netbackup]# check_tape_pool -p Scratch
OK - available tapes in Scratch : 35|availability=35;

[root@netbackup]# check_tape_pool -p Scratch -l 10 -u 15
OK - available tapes in Scratch : 35|availability=35;

root@netbackup]# check_tape_pool -p Scratch -l 20 -u 40
WARNING - available tapes in Scratch : 35|availability=35;

[root@netbackup]# check_tape_pool -p Scratch -l 40 -u 50
CRITICAL - available tapes in Scratch : 35|availability=35;

[root@netbackup]# check_tape_pool -p Scratch -r -l 10 -u 15
CRITICAL - available tapes in Scratch : 35|availability=35;
