Project Notes

Part of the Advanced Nagios Plugins Collection Download it here: https://github.com/harisekhon/nagios-plugins check_elasticsearch_node_stats.pl Nagios Plugin to check the stats for a given Elasticsearch node - 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 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--- 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. For a convenient list of all stats one per line use -vv usage: check_elasticsearch_node_stats.pl [ options ] -H --host ElasticSearch host ($ELASTICSEARCH_HOST, $HOST) -P --port ElasticSearch port ($ELASTICSEARCH_PORT, $PORT, default: 9200) -N --node Elasticsearch node ($ELASTICSEARCH_NODE) -K --key Stat Key(s) to fetch (eg. indices.docs.count, http.current_open, fs.total.available_in_bytes). Multiple keys may be comma separated. Optional, all stats will be printed if no specific stat(s) requested --list-nodes List Elasticsearch nodes -w --warning Warning threshold or ran:ge (inclusive) -c --critical Critical threshold or ran:ge (inclusive) -t --timeout Timeout in secs (default: 10) -v --verbose Verbose mode (-v, -vv, -vvv ...) -h --help Print description and usage options -V --version Print version and exit
