check_elasticsearch_node_shards.pl

Nagios Plugin to check the number of shards assigned to a given Elasticsearch node in a cluster

Should specify an Elasticsearch node name rather than a hostname/FQDN/IP (see --list-nodes), as sometimes hosts may have more than once instance or client nodes like logstash-<fqdn>-<d+>-<d+> which
also share the same hostname/FQDN and will result in multiple ambiguous matches, resulting in an UNKNOWN error condition to flag for user to correct this and be more specific.

Tested on Elasticsearch 1.4.0, 1.4.4

usage: check_elasticsearch_node_shards.pl [ options ]

-H --host ElasticSearch host ($ELASTICSEARCH_HOST, $HOST)

-N --node Elasticsearch node ($ELASTICSEARCH_NODE)
--list-nodes List Elasticsearch nodes
-w --warning Warning threshold or ran:ge (inclusive, default: 1:)
-c --critical Critical threshold or ran:ge (inclusive, default: 10000)
-t --timeout Timeout in secs (default: 10)
-v --verbose Verbose mode (-v, -vv, -vvv ...)
-h --help Print description and usage options
