| 3 | # Veritas Cluster System monitor for Nagios. | ||

| 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 | ||
