This repository contains Ansible playbooks for configuring the Node Exporter and Prometheus server

README

Overview

This repository contains an Ansible playbook for configuring the Node Exporter and Prometheus server to automate server and network management efficiently.

What is Prometheus?

Prometheus is an open-source tool for event monitoring and alerting, written in Go. It stores metrics in a time series database using an HTTP pull model, allowing for real-time alerting with flexible queries. The Node Exporter is a Prometheus component that exposes OS and hardware metrics.

Why Ansible?

Ansible is an agentless automation and configuration tool that simplifies the deployment of Prometheus, enabling you to configure multiple servers in just a few minutes.
