As a distributed key-value store, etcd is designed to manage configuration settings across clusters of Docker containers or machines. Activating the Datadog etcd integration ensures consistent and up-to-date configurations throughout your cluster. The integration provides real-time monitoring of etcd's throughput, including metrics on successful directory or key creation, writes, updates, deletes, and atomic operations. Additionally, it tracks package and bandwidth send and receive rates, append requests, and failure rates of the leader's Raft RPC requests to followers. Latency between the leader and its followers is also monitored, with metrics available for current, average, minimum, maximum, and standard deviation latency. The integration also provides additional metrics such as watcher counts, expire count, and auto-tagging with leader/follower status. With the Datadog etcd integration, users can set alerts on anomalous changes to their event stream and notify humans of large anomalies, ensuring the health of their etcd cluster.
