DevOps — Monitoring and Logging

Monitoring and logging are crucial in DevOps to track performance, detect issues, and understand system behavior. Monitoring tools like Prometheus, Grafana, and Datadog provide real-time metrics like CPU usage, memory, and response times. Logging tools like ELK Stack (Elasticsearch, Logstash, Kibana) collect and visualize logs to troubleshoot problems quickly.

Example: Using Grafana dashboards to monitor server performance and ELK to debug errors.
