Ultimate DevOps Monitoring Project

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

Use Cases

Blackbox Exporter:
- Monitor the uptime and performance of web applications, ensuring customer-facing websites are available and respond within acceptable time limits.
Node Exporter:
- Monitor server health, including memory usage, CPU load, and disk space, to identify and resolve resource bottlenecks on critical servers.
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.
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.
