Reporting

The Reporting screen displays graphs of system information for CPU, disk, memory, network, NFS, partition, target, UPS, ZFS, and system functions. Use the dropdown in the upper right corner to select between reporting graph display options. The CPU report displays by default.

To configure a third-party reporting integration, such as Graphite, click Exporters to open the Reporting Exporters screen.

The following sections provide examples of each report graph. There are a few controls to change the default graph view:

• The Auto Refresh toggle updates the graphs with the latest reporting data every few seconds. When active, the graph resets to the chosen Reset Zoom view every time the reporting data updates. Disable Auto Refresh before manually zooming in on any section of the graph.
• Step Back () moves the graph backward in time by whatever time increment is currently active in Reset Zoom.
• Step Forward () moves the graph forward in time by whatever time increment is currently active in Reset Zoom. The default graph view is to show the latest data, which disables this button.
• Zoom Out () adjusts the time period shown in the graph between 1 Hour, 1 Day, 1 Week, 1 Month, and 6 Month views.
• The Reset Zoom indicator shows which time value is active for the graph. The default 1 Hour is the default (and minimum) time period that can be active. When Zoom Out is active, click Reset Zoom to reset the graph view to 1 Hour.
• Zoom In () adjusts the time period shown in the graph between 1 Hour, 1 Day, 1 Week, 1 Month, and 6 Month views. This is active when the graph changes from the default 1 Hour view.

To manually adjust the vertical or horizontal precision of the graph, disable Auto Refresh, then click and drag within the graph view. A left-to-right (or vice-versa) motion increases the horizontal view precision, while an up-to-down (or vice-versa) motion increases the vertical precision.

Displays the CPU Temperature, CPU Usage, and System Load graphs.

CPU graphs show the amount of time spent by the CPU in various states such as executing user code, executing system code, and being idle. Graphs of short-, mid-, and long-term load are shown, along with CPU temperature graphs.

Displays graphs for each selected system disk and by report type.

Disk graphs show read and write statistics on I/O, percent busy, latency, operations per second, pending I/O requests, and disk temperature. Use the Select Disks dropdown list to select the disks and the Select Reports dropdown to select the report types to display.

Disk Report Setting Options

Setting	Description
Select All	Displays all available graphs for any or all disks selected on the Disks dropdown list.
Disk Temperature	Displays the minimum, maximum, and mean temperature readings for the disk selected.
Disk I/O	Displays the disk read and write I/O stats in bytes/s.

Temperature monitoring for the disk is disabled if HDD Standby is enabled. Check the Storage > Disks Edit Disk* configuration form for any or all disks in the system if you do not see the temperature monitoring graph.

Large petabyte systems may report storage numbers inaccurately. Storage configurations with more than 9,007,199,254,740,992 bytes will round the last 4 digits.

For example, a system with 18,446,744,073,709,551,615 bytes reports the number as 18,446,744,073,709,552,000 bytes.

Displays both the Physical memory utilization and Swap utilization graphs.

Memory graphs display memory usage and swap graphs display the amount of free and used swap space.

Displays an Interface Traffic graph for each interface in the system.

Click Here for More Information

Network graph report received and transmitted traffic in megabytes per second for each configured interface.

Displays both the Processes and Uptime graphs.

Click Here for More Information

System graphs display the number of processes grouped by state, sleeping, running, stopped, zombies and blocked, and system uptime.

Displays the UPS Charging percentage, UPS Runtime, UPS Voltage - Battery, UPS Voltage - Input, UPS Voltage - Output, UPS Input Current, UPS Input Frequency, UPS Input Load, and UPS Temperature.

The UPS service must be configured with a compatible Uninterruptible Power Supply (UPS) device.

Displays the ARC Size, ARC Hit Ratio, ARC Requests demand_data, ARC Requests demand_metadata, ARC Requests prefetch_data, and ARC Requests prefetch_metadata graphs with the Arc and L2 gigabytes and hits (%), and the hits, misses and total number of requests.

Click Here for More Information

ZFS graphs show compressed physical ARC size, hit ratio, demand data, demand metadata, and prefetch data and metadata.

Exporter on the Reporting screen opens the Reporting Exporter screen. The Reporting Exporters screen displays reporting exporters configured on the system. Exporting enables TrueNAS to send Netdata reporting metrics to another time-series database. Exporters send Netdata reporting records as JSON objects to third-party reporting collection cloud services or applications installed on servers. For more information, see the Netdata exporting reference guide.

Add opens the Add Reporting Exporter screen.

Use the Add Reporting Exporter screen to configure third-party reporting integrations.

Additional settings populate based on the selected Type option.

See Adding a Reporting Exporter for guidance with configuring a Graphite exporter on TrueNAS.
