Module 7: Monitoring & Logging

Ensuring system reliability and observability.

7.1 Prometheus & Grafana

Prometheus is an open-source systems monitoring and alerting toolkit. Grafana is a multi-platform open source analytics and interactive visualization web application.

7.2 ELK Stack (Elasticsearch, Logstash, Kibana)

The ELK Stack is a collection of three open-source products — Elasticsearch, Logstash, and Kibana. They are used for searching, analyzing, and visualizing log data in real time.

7.3 Distributed Tracing

Distributed tracing is a method used to profile and monitor applications, especially those built using a microservices architecture. Tools like Jaeger and Zipkin are commonly used.

7.4 Alerting Strategies

Setting up effective alerts to notify the operations team of issues before they impact users. Avoiding alert fatigue.

🎯 Practical Exercise

Set up a Prometheus server to scrape metrics from a Node Exporter and visualize the data in a Grafana dashboard.
