Monitoring Using MCS and the CLI

The Overview displays a summary of information about the cluster in six panes including information on cluster health, activity, and usage.

Note: During installation using the MapR Installer, you can configure metrics and logging using settings on the Monitoring page of the MapR Installer user interface. The metrics collection infrastructure must be installed because the MapR Control System relies on these metrics to provide graphs and charts in the Overview page. If the metrics collection infrastructure is not installed, you cannot visualize the metrics in the Overview page. If you want, you can install metrics collection or logging at any time by selecting the feature during an Incremental Install.

The following sections provide information about each pane.
