Boto3 for fetching the cluster health of OpenSearch domain

Question

I am trying to fetch the cluster health of Opensearch domain through the boto3, but I do not find any method for the same. How to solve this problem?

Answer 1

You do not need boto to fetch cluster health of AWS Opensearch domain. You can just make a GET request using the python requests library.

import requests
OPENSEARCH_ENDPOINT = "your_opensearch_endpoint"
res = requests.get(f'https://{OPENSEARCH_ENDPOINT}/_cluster/health')
print(res.json())

Response:

{
  "cluster_name": "<acc_id>:<opensearch_domain_name>",
