TrueNAS SCALETrueCommand Nightly Development Documentation
This content follows experimental early release software. Use the Product and Version selectors above to view content specific to a stable software release.

System Management

The TrueCommand dashboard provides status overviews of each connected TrueNAS system.


For information on the Top Bar and its options, refer to the Interface Overview article in the Getting Started Documentation.

System Cards

Each system has a unique card to display statistics. When the system has an alert, an Alerts bubble appears next to the system version to show how many alerts there are for that specific system. See Alert Management for further information.


The Storage graph shows how many pools and drives the system is using. It also displays used and available storage by size and percentage.

ARC MISS shows how often the system is using disks instead of the ARC cache. Anything above 0% means that the system is using RAM. The numbers vary by use case and workload.

There are also several “hot spots” on the card that open system-specific areas for management.

Clicking the system name on the card shows an expanded view of the system with more Single System Management options.

Clicking the Alerts bubble next to the system version opens an expanded system information screen that lists the current system alerts.

Clicking DRIVES, DISK WRITE, DISK READ displays the disk activity graph.

Clicking NET displays the Net Activity graph.

Clicking CPU displays the CPU Usage percentages graph.

Clicking TEMP displays the CPU Temperature percentages graph.

Clicking NFS and SMB opens a Services window that allows users to stop/start services for the system.

Clicking VM opens a Virtual Machines window that allows users to start/stop VMs on the system.

Clicking APPS (SCALE) or Jails (CORE 12.x) allows users to start/stop apps/jails on the system.

Options Menu


The Options menu has several shortcuts to simple tasks.

  • Edit opens the edit window for the TrueNAS connection details and nickname.
  • Users and Groups lets users manage NAS users and groups.
  • Update updates the TrueNAS system.
