3 | # Veritas Cluster System monitor for Nagios. | ||
4 | # Written by Aaron Bostick (abostick@mydoconline.com) | ||

7 | # Usage: check_vcs {-g <vcs_group> | -r <vcs_resource> } -s <vcs_system> [-n] | ||
8 | # | ||
9 | # Description: | ||
10 | # | ||
11 | # This plugin is just a perl wrapper to the vcs commands hagrp and hares. | ||
12 | # You specify what group/resource and system you want the status for, and | ||
13 | # the plugin returns a status code based on the output of either hagrp or | ||
14 | # hares. | ||
15 | # | ||
16 | # Normal hagrp/hares status codes are ONLINE and OFFLINE depending on where the | ||
17 | # cluster service currently lives. I have added an option, -n, which makes | ||
18 | # the expected state to be OFFLINE rather than ONLINE so you can run the | ||
19 | # plugin on both sides of the cluster and will receive critical alerts when | ||
20 | # the cluster fails over i.e. a proper failover will make the standby node | ||
21 | # go from OFFLINE to ONLINE for the group, so an ONLINE status should alert | ||
22 | # you! (You do want to know when the cluster fails over, right? :)) | ||
23 | # | ||
24 | # Output: | ||
25 | # | ||
26 | # This plugin returns OK when hagrp/hares -state <grp> -sys <system> returns | ||
27 | # ONLINE (or OFFLINE if -n is specified). Any other hagrp/hares string returns | ||
28 | # CRITICAL... Would a WARNING ever be justified??? UNKNOWN is returned if | ||
29 | # hagrp/hares cannot run for some reason. | ||
30 | # | ||
31 | # Examples: | ||
32 | # | ||
33 | # Make sure group oracle is ONLINE on server dbserver1: | ||
34 | # check_vcs -g oracle -s dbserver1 | ||
35 | # | ||
36 | # Make sure group oracle is OFFLINE on server dbserver2: | ||
37 | # check_vcs -g oracle -s dbserver2 -n | ||
38 | # | ||
39 | # Make sure resource oraip is ONLINE on server dbserver1: | ||
40 | # check_vcs -r oraip -s dbserver1 | ||
41 | # | ||
42 | # Make sure resource oraip is OFFLINE on server dbserver2: | ||
43 | # check_vcs -r oraip -s dbserver2 -n | ||
