Tools for collecting etcd metrics and logs

In this text, we learn about monitoring etcd clusters using tools like Prometheus, Grafana, and etcdctl. We explore how to view a snapshot of etcd metrics via the /metrics endpoint and expand our visibility with Prometheus and Grafana. Additionally, we discuss checking endpoint health and performance with etcdctl and using journalctl to view etcd logs for greater context around metric data. Finally, the text mentions that in Part 3 of this series, it will show how Datadog provides a unified platform for monitoring etcd clusters alongside Kubernetes control plane and workloads, as well as infrastructure.
