What is the method to check the status of the ES cluster?

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

1. Send an HTTP request using the curl command.

curl -X GET "http://<es_host>:<es_port>/_cluster/health"

In this case, is the hostname or IP address of the Elasticsearch cluster, and is the HTTP port, which defaults to 9200. This command will display the health status of the cluster, where green indicates it is healthy, yellow indicates warnings, and red indicates errors.

1. You can query using Elasticsearch’s API by using any HTTP client library or tool, such as curl, Postman, or Python’s requests library. Here is an example code for using the requests library in Python:

import requests

response = requests.get("http://<es_host>:<es_port>/_cluster/health")
print(response.json())

Similarly, refers to the hostname or IP address of the Elasticsearch cluster, with denoting the HTTP port, typically set to 9200. The sample code will retrieve the health status information of the cluster.

1. search engine that allows for the searching and analysis of data

elasticsearch _cluster/health

This command will provide information on the health status of the cluster.

You can check the status information of the Elasticsearch cluster using any method.
