The mongo-monitor CLI is a lean and simple tool to check the status of a MongoDB server or cluster. The code is on GitHub: github.com/dwmkerr/mongo-monitor Here’s how it looks in action: In this animation I am monitoring a simple sharded cluster, and running some example maintenance operations, adding a node to a replicaset, stepping down a primary and shutting down a replicaset node. A simple CLI which shows the status in real-time can be very useful to keep open when performing admin, letting you see how your changes affect the cluster as you work on it.
