check_elasticsearch_cluster_stats.pl

Nagios Plugin to check Elasticsearch cluster stats

- Can fetch one or more given stats (fetches all stats if no specific ones are specified)
- Optional --warning/--critical threshold ranges if given are applied to the first float value found (--key order is preserved for this reason if wnating to return more than one thing at a time but still
have a threshold on one of them, the first one in the --key list)
- Will output stats KB/MB/GB/PB values in brackets in verbose mode for size_in_bytes stats

For a convenient list of all stats one per line use -vv
