Ultimate DevOps Monitoring Project

Setting Up Prometheus, Node Exporter, Blackbox Exporter, and Alertmanager: A Step-by-Step Guide

Use Cases

1. Blackbox Exporter:

   • Monitor the uptime and performance of web applications, ensuring customer-facing websites are available and respond within acceptable time limits.

2. Node Exporter:

   • Monitor server health, including memory usage, CPU load, and disk space, to identify and resolve resource bottlenecks on critical servers.

3. Alertmanager:

   • Set up alert rules to receive email notifications when certain conditions are met, such as server downtime or metrics crossing thresholds, ensuring prompt attention to issues before escalation.

4. Prometheus:

   • Comprehensive monitoring of infrastructure and applications, enabling visualization of metrics, setting up alerting rules, and deep diving into historical data for troubleshooting and performance optimization.

Prerequisites

• Ensure you have wget and tar installed on both VMs.

• Ensure you have appropriate permissions to download, extract, and run these binaries.

• set up two virtual machines (VM & Monitoring-tools)
