System Stats

This window displays graphs of:

• CPU Utilisation for each CPU (%).
  
• Load Average.
  
• Number of process running.
  
• GPU VRAM usage (GB) and GPU Utilisation (%).
  
• System memory usage (GB).
  
• System disk i/o in Bytes/s (or with power of 10 prefix).
  
• System network i/o in bits/s (or with power of 10 prefix).
  
• System fan speeds in RPM.
• Power consumption in Watts (W).

The window contains panes for each graph that can be resized (vertically) by clicking on the size control located between each of the panes.

Each pane can be collapsed by moving the control all the way to the adjacent pane.

The displayed font can be modified with the Format/Font menu.

The window is refreshed every second, each second being represented by 2 pixels on the horizontal axis of the graphs.

Expanding the window horizontally will show previous history.

Expanding the window vertically will proportionately resize each pane.

Clicking on a pane displays a small popover window that allows you to modify the color of each graph.

You can adjust the number of rows used to display individual CPUs with the Max CPU rows control in Preferences.

You can adjust the appearance and disable the grid lines of the window using the controls in Preferences

Each column also includes a dummy pane. You can collapse this pane or adjust it’s size to give yourself a more aesthetically pleasing layout.

You can display one of the graphs in the Dock (replacing the Application Icon). You select the graph to display from either the View/Dock Icon menu, or by right(control)-click on the CPUSetter icon in the Dock then selecting the type of Dock display that you want.

CPU

• Usage due to user processes is shown in green.
  
• Usage by the system kernel is shown in red.
  
• Adjust the number of rows with Preferences.

Load Average
Load Average measures the number of processes in the system run queue averaged over 1 minute, 5 minute and 15 minute intervals.
* 1 Minute load average - blue.
* 5 Minute load average - green.
* 15 Minute load average - red.

Processes

• Processes owned by you are shown in blue.
  
• Processes owned by other users are shown in orange.

GPU

• VRAM usage is shown in blue.
  
• Utilisation is plotted as an orange line graph.

System Memory

• Wired memory is shown in red.
  
• Inactive memory is shown in green.
  
• Active memory is shown in blue.

Disk I/O

• Read byte rate is shown in blue.
  
• Write byte rate is shown in red.
  
• Right click in a pane will show partitions/volumes on the disk, including synthesised (e.g. APFS) volumes.

Display of Data rates or I/O rates can changed via the pull down menu at the top of the column.

Network I/O

• Read bit rate is shown in blue.
  
• Write bit rate is shown in green.

System Fans

• Nominal maximum RPM is shown as a red line.
• Current fan speed (RPM) is shown in blue.
  
• Nominal minimum RPM is shown as a green line.

System Power Consumption

• Total power usage is shown in blue.
• CPU power usage is shown in green.
  
• GPU power usage is shown in red.

NB: M1 Macs do not report CPU and GPU power usage.
