Elasticsearch-Manager

Elasticsearch-Manager provides both a commandline utility and libraries for performing basic management activities on an Elasticsearch cluster.

For a list of all supported actions, please run: $ elasticsearch-manager --help

Installation

gem install elasticsearch-manager

List IPs for all cluster members

$ elasticsearch-manager --cluster-hostname elasticsearch.example.com \
                        --port 9200 status \
                        list-nodes
10.0.0.3 -- master
10.0.0.1
10.0.0.2

Display the count of all shard states for each node in the cluster

$ elasticsearch-manager --cluster-hostname elasticsearch.example.com \
                        --port 9200 status \
                        shard-state
10.0.0.1:   STARTED: 8       INITIALIZING: 0    RELOCATING: 0
10.0.0.2:   STARTED: 8       INITIALIZING: 0    RELOCATING: 1
10.0.0.3:   STARTED: 7       INITIALIZING: 1    RELOCATING: 0

Check the current status of a cluster

$ elasticsearch-manager --cluster-hostname elasticsearch.example.com \
                        --port 9200 status \
                        status
The Elasticsearch cluster is currently: green

Restart a single node by ip or hostname

$ elasticsearch-manager --hostname localhost \
                        --port 9200 \
                        restart-node

If using a dns name, confirm that the dns resolves to a single host. If a record that references a load balancer is used, the behavior of this command is undefined.

Perform a rolling restart of a cluster

$ elasticsearch-manager --cluster-hostname elasticsearch.example.com \
                        --port 9200 status \
                        rolling-restart
