Nagios check script for elasticsearch
This is a simple script to check the status of an elasticsearch cluster. It now supports elasticsearch 6.3.2 with or without x-pack authentication.
Usage:
./check_elasticsearch -H es1.mysite.com -P 9200 -o /tmp [ -a ] [ -u <username> -p <password> ]
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
Removed reference to Chef cookbook since this fork won't support it.
Elastic authentication via certificate and private kay Usage: ./check_elasticsearch -H elasticsearch.mydomain -s --certificate /mypath/certs/admin.crt.pem --private-key /mypath/certs/private/admin.key.pem
Script is a modified version of check_phpfpm by MAB.
