This is a simple script to check the status of an elasticsearch cluster.
Usage:
./check_elasticsearch -H es1.mysite.com -P 9200 -o /tmp
This will output the standard Nagios format:
OK - elasticsearch (elasticsearch) is running. status: green; timed_out: false; number_of_nodes: 1; number_of_data_nodes: 1; active_primary_shards: 2; active_shards: 2; relocating_shards: 0; initializing_shards: 0; unassigned_shards: 0 | 'active_primary'=2 'active'=2 'relocating'=0 'init'=0
OK / WARNING / CRITICAL correspond to the status being "green", "yellow", or "red" respectively.
If you have a Graphite server you can send data to it via:
./check_elasticsearch -H es1.mysite.com -P 9200 -c graphite.foo.com -C 2003
This will output data to the following metric prefix:
system.$cluster_name.cluster.app.elasticsearch.cluster
If you use Chef there is a cookbook for installing this plugin at https://github.com/cjs226/check_elasticsearch_cookbook.
Script is a modified version of check_phpfpm by MAB.
Enjoy.
