Reporting
TrueNAS has a built-in reporting engine that provides helpful graphs and information about the system.
TrueNAS uses Netdata to gather metrics, create visualizations, and provide reporting statistics.
The built-in Netdata UI, accessible from the Netdata button on the Reporting screen in TrueNAS 24.04 and 24.10, is removed in TrueNAS 25.04 (and later) for security hardening. Users wishing to continue using the Netdata UI to monitor system reports can install the Netdata application.
