MapR Control System

The MapR Control System (MCS) provides a graphical control panel for cluster administration with all the functionality of the command-line or REST APIs. The MCS provides job monitoring metrics and helps you troubleshoot issues, such as which jobs required the most memory in a given week or which events caused job and task failures.

The MCS Dashboard provides a summary of information about the cluster including a cluster heat map that displays the health of each node; an alarms summary; cluster utilization that shows the CPU, memory, and disk space usage; services running across the cluster; the number of available, unavailable, and under replicated volumes; MapReduce jobs. Links in each pane provide shortcuts to more detailed information.

The MCS provides various views, which you can use to monitor and configure your cluster.
