This final part is about combining and coalescing everything you’ve learned and moving even further. You’ll learn how to monitor and troubleshoot a running Jenkins cluster. We’ll start by exposing Jenkins metrics with Prometheus and build an interactive dashboard with Grafana. Next, I will demonstrate how to stream Jenkins logs to a centralized logging platform based on the ElasticSearch, Logstash, and Kibana (ELK) stack. Finally, I will share tips and best practices to secure and maintain Jenkins.
