Project Notes
Part of the Advanced Nagios Plugins Collection, download it here: https://github.com/harisekhon/nagios-plugins * Check we have an HBase Root RegionServer assigned: check_hbase_root_regionserver_znode.pl -H or check_zookeeper_znode.pl -H -z /hbase/root-region-server usage: check_hbase_root_regionserver_znode.pl [ options ] -H --host ZooKeeper nodes to connect to, should be a comma separated list of ZooKeepers the same as are configured on the ZooKeeper servers themselves (node1:2181,node2:2181,node3:2181) -P --port Port to connect to on ZooKeepers for any nodes not suffixed with : (defaults to 2181) -z --znode Znode to check exists. Useful for a variety of checks of ZooKeeper based services like HBase and SolrCloud -d --data Expected data to be contained in the znode. Optional check. This is a partial substring match, for more control use --regex with anchors. Careful when specifying non-printing characters which may appear as ?, may need to use regex to work around them with ".+" to match any character -r --regex Regex of expected data to be contained in the znode, case insensitive. Optional check. Checked after --data -u --user User to connect with (Not tested. YMMV. optional) -p --password Password to connect with (Not tested. YMMV. optional) -w --warning Warning threshold or ran:ge (inclusive) for znode age (optional) -c --critical Critical threshold or ran:ge (inclusive) for znode age (optional) -n --null Do not check znode contents, use on null znodes such as SolrCloud /solr/live_nodes/:8983_solr as the API segfaults when trying to retrieve data for these null znodes -h --help Print description and usage options -t --timeout Timeout in secs (default: 10) -v --verbose Verbose mode (-v, -vv, -vvv ...) -V --version Print version and exit
