To check the status of Elasticsearch nodes, you can use the following methods:

  1. display information about nodes
GET /_cat/nodes?v

This will generate a table containing the status of nodes, such as their ID, IP address, role, and status.

  1. health of the cluster
GET /_cluster/health

This will provide information about the health status of the cluster, including the number of active nodes, unassigned shard count, and cluster status.

  1. to form into loops or ringlets
curl -XGET 'http://localhost:9200/_cat/nodes?v'

Alternatively:

curl -XGET 'http://localhost:9200/_cluster/health'

Be sure to replace ‘localhost:9200’ with the actual host and port where Elasticsearch is running.

Regardless of the method used, it is possible to view the status information of the nodes from the returned results.
