Have you worked with monitoring and logging tools such as Prometheus, Grafana, ELK stack (Elasticsearch, Logstash, Kibana)? Describe your experience.

Yes, I've used Prometheus for monitoring and Grafana for visualization. Prometheus collected metrics from various services and infrastructure components. Grafana dashboards were created to visualize these metrics, enabling proactive issue detection. I've also used ELK stack for centralized logging. Elasticsearch stored logs, Logstash parsed and enriched them, and Kibana provided a user-friendly interface for searching and analyzing logs.
