Process Monitor
- OS:
🪐 Platform-independent
The Process Monitor watches running OS processes and reports system activity as long as matching processes are alive and busy. Each <Process> entry defines a logical group: the text node is a regular expression matched against process image names, and enabling watchChildren extends the group to include any processes spawned by a match. This makes it straightforward to track browsers or IDE families where work happens across several child processes under a common parent.
Optionally, a CPU threshold (minCPU) can be configured so that processes that are running but idle — sitting in the background with negligible CPU usage — do not prevent sleep. When CPU use drops below the threshold, the onIdle event fires for that group; onStart and onStop fire when the first process in a group appears or the last one exits.
The available actions cover forceful process termination with an optional graceful shutdown timeout. The configuration reference documents all attributes. On Windows, Desomnia uses the ETW API for near real-time process event notifications instead of polling; the performance page explains the difference and how to configure the poll interval if needed.
