3 minute read.
Last Modified 2023-11-16 16:21 ESTThe Reporting screen displays graphs of system information for CPU, disk, memory, network, NFS, partition, target, UPS, ZFS, and system functions. The CPU report displays by default.
| Setting | Description |
|---|---|
| CPU | Displays the CPU Temperature, CPU Usage, and System Load graphs. |
| Disk | Displays graphs for each selected system disk and by report type. |
| Memory | Displays both the Physical memory utilization and Swap utilization graphs. |
| Network | Displays an Interface Traffic graph for each interface in the system. |
| System | Displays both the Processes and Uptime graphs. |
| ZFS | 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. |
The following sections provide examples of each report graph.

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.

Disk graphs shows 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.
| 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 reading 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.
