TrueNAS has a built-in reporting engine that provides helpful graphs and information about the system.


TrueNAS uses Graphite to gather metrics and create visualizations.

The Reports Configuration menu lets you control how TrueNAS displays the graphs.

Reports Configuration


General Options

Report CPU usage in PercentReports CPU usage in percent instead of units of kernel time.
Graphite Separate InstancesSends the plugin instance and type instance to Graphite as separate path components: host.cpu.0.cpu.idle. Disabling sends the plugin and plugin instance as one path component and type and type instance as another: host.cpu-0.cpu-idle.
Remote Graphite Server HostnameRemote Graphite server host name or IP address.
Graph age in MonthsMaximum time (in months) TrueNAS stores a graph. Allowed values are 1-60. Changing this value causes the Confirm RRD Destroy dialog to display. Changes do not take effect until TrueNAS destroys the existing reporting database.
Number of Graph PointsThe number of points for each hourly, daily, weekly, monthly, or yearly graph. Allowed values are 1-4096. Changing this value displays the Confirm RRD Destroy dialog. Changes do not take effect until TrueNAS destroys the existing reporting database.
Reset to DefaultsResets all entered values and settings back to defaults.
TrueNAS clears the report history when you change Report CPU, Graph Age, or Graph Points.

TrueNAS saves and preserves reporting data across system upgrades and reboots so you can view usage trends over time.

Since TrueNAS writes reporting data frequently, do not store it on the boot pool or OS device. TrueNAS saves reporting data in /var/db/collectd/rrd/.
