Installing Additional MapR Core Features

New features, such as MapR Monitoring, may require the installation of additional packages after an upgrade.

MapR Monitoring

MapR Monitoring, a Spyglass initiative, provides the ability to collect, store, and view metrics and logs for nodes, services, and jobs/applications. You can only install MapR Monitoring after you upgrade ecosystem components.

To install MapR Monitoring without the MapR Installer, see Step 8: Install Metrics Monitoring and Step 9: Install Log Monitoring.
To install MapR Monitoring with the MapR Installer, launch the MapR Installer URL ( https://<hostname/IPaddress>:9443) and select the Incremental Install option. With the incremental installation option, you can install new packages and also install MapR Monitoring.
