Get TrueNAS system information: version, uptime, CPU, RAM, boot time.

List all active TrueNAS alerts with severity levels.

List all services and their running status (SMB, NFS, SSH, etc.).

List recent system jobs with status, progress, and errors.

Query audit log entries (auth events, config changes).

List all configured cron jobs.

Get boot pool health status.

List all storage pools with health, capacity, and fragmentation.

Get detailed pool status with VDEV topology and error counts.

List datasets with usage and quota info. Always specify a pool to avoid timeouts on large systems.

Get detailed info for a specific dataset.

Create a new ZFS dataset.

Update dataset properties (compression, quota, comments, etc.).

Delete a dataset. Requires confirm=True.

List ZFS snapshots. Always specify a dataset to avoid timeouts on large systems.

Create a manual ZFS snapshot.

Delete a snapshot. Requires confirm=True. Snapshot format: dataset@name.

Rollback dataset to snapshot. Requires confirm=True. WARNING: destroys newer data.

Clone a snapshot to a new dataset.

List automated snapshot task schedules.

List all SMB shares.

Create a new SMB share. Path must start with /mnt/.

Delete an SMB share by ID. Requires confirm=True.

List all NFS exports.

Create a new NFS export. Path must start with /mnt/.

Delete an NFS export by ID. Requires confirm=True.

List all installed apps with their state.

Get the full configuration of a specific app.

Update app configuration.

WARNING: This is a REPLACE operation, not a merge. Any config keys not included will revert to defaults. Always get current config first with get_app_config, modify the needed values, and send the complete config.

Install an app from the catalog.

Delete an installed app. Requires confirm=True.

Start a stopped app.

Stop a running app.

Upgrade an app to the latest available version.

Redeploy an app with its current configuration.

Browse the app catalog for available apps to install.

List all virtual machines with their state, CPU, and RAM configuration.

Start a virtual machine.

Stop a virtual machine. Attempts graceful shutdown first, forces after timeout.

RAM/CPU changes require full stop+start from TrueNAS — in-guest reboot does NOT re-allocate resources.

Update VM configuration (RAM, CPUs, etc.).

Note: RAM/CPU changes only take effect after a full stop+start from TrueNAS — rebooting from inside the VM does NOT re-allocate resources.

List network interfaces with IPs and link state.

Get network configuration: DNS servers, gateway, hostname.

List available reporting graphs and their identifiers.

Available graphs include: cpu, cputemp, memory, disk, interface, load, uptime, arcsize, disktemp, and more. Some graphs require an identifier (disk name for 'disk'/'disktemp', interface name for 'interface').

Get historical reporting data for a graph.

Units: HOUR (1h), DAY (24h), WEEK, MONTH, YEAR. Some graphs need an identifier (e.g., disk name 'sda' for disk graphs, interface name 'enp5s0' for network graphs). Response format: [{name, identifier, data: [[unix_timestamp, value], ...]}]. Memory/ARC values in bytes, CPU in percentage.

List all system users.

Get details for a specific user.

Create a new system user.

Update user properties.

Delete a user. Requires confirm=True.

List all disks with model, serial number, size, and pool membership.

Get current temperatures for all disks.

List all cloud sync tasks with their status and schedule.

Trigger a cloud sync task to run immediately.

List all replication tasks with their status.

Trigger a replication task to run immediately.

List SMART test results for all disks.

Run a SMART test on specified disks. test_type: SHORT or LONG. Note: TrueNAS 25.10 removed SMART scheduling from the API — these are manual tests only.

Check for available TrueNAS system updates.

List all SSL/TLS certificates.
