You can use the Installer to enable or disable metrics collection and logging during a new or incremental installation.
During installation using the Installer, you can configure metrics and logging using settings on the Monitoring page of the Installer user interface. Installing the metrics collection infrastructure is selected by default because the control system relies on these metrics to provide graphs and charts. Logging is deselected by default.
If you did not install metrics collection or logging during your initial installation, you can add it later by selecting the feature during an Incremental Install.
