check_elasticsearch_node_disk_percent.pl

Nagios Plugin to check the disk % space used on a given Elasticsearch node in a cluster

Will test the first node with matching hostname/FQDN/IP or Elasticsearch node name. Client nodes like LogStash will not be counted as they don't expose disk % but if co-locating more than one
Elasticsearch data node instance on a host you should supply the Elasticsearch node instance name instead to be more specific otherwise you will only be able to test the first instance found
(--list-nodes shows all available hosts/IP and instance names).

For regular deployments with one Elasticsearch instance per server it's perfectly fine to just specify the IP or the hostname/FQDN for convenience.

For convenience --node defaults to same as --host, which may not match if you're specifying a short hostname for --host and elasticsearch is reporting an FQDN, in which case you should specify the node
explicitly as shown by the output of --list-nodes.

Tested on Elasticsearch 1.4.0, 1.4.4
