Why Monitor Your Elasticsearch Cluster?

Before diving into the “how”, it’s essential to understand the “why”. By enabling monitoring on your Elasticsearch cluster:

  • You gain insights into cluster performance.
  • Diagnose and troubleshoot issues quicker.
  • Make data-driven decisions for scaling and optimizing.

Steps to Enable Elasticsearch Cluster Monitoring

Understand Your Cluster

Before making any changes, it’s pivotal to understand your setup. The Elasticsearch cluster used in this example is a 3-node cluster with Kibana, primarily for proof of concept.
