Monitoring Streams

The speed at which messages flow from producers to partitions and from partitions to consumers depends on the performance of your producers, the cluster nodes hosting partitions, and your consumers.

You can monitor streams in the MapR Control System and using the CLI.

Monitoring Streams Operations Using the MapR Control System

Log in to MCS and click Data > Streams.
The Stream Operations pane displays the (top) nodes where the most number of messages were produced and consumed.
