Introduction

Prometheus is a powerful monitoring and alerting toolkit that collects metrics from various services and systems. Elasticsearch exporter is a Prometheus exporter that collects metrics from Elasticsearch and exposes them for monitoring and analysis. In this blog post, we will explore how to set up a custom Prometheus dashboard specifically for the Elasticsearch exporter.

Prerequisites

Before proceeding with the setup, ensure that you have the following prerequisites:

• Prometheus installed and configured
• Elasticsearch exporter installed and running
• Basic knowledge of Prometheus queries
