Emitter gearshape.2

Process Monitor

Streams CPU and memory usage for a specific application.

The Process Monitor emitter tracks a single application's resource consumption over time. On each poll interval it reports the process's CPU usage percentage, memory footprint in megabytes, and whether the process is currently running. This is ideal for monitoring resource-hungry apps, detecting runaway processes, or building per-app usage dashboards.

Select the target application using the built-in app picker, which lists all installed applications on your Mac. If the selected app is not running when the emitter fires, the isRunning variable will be false and the CPU/memory values will be zero.

⚠️

One emitter per workflow

A workflow streams from a single emitter at a time. If you place two emitters (for example a Process Monitor and a Resource Monitor) in the same workflow, only one will stream — the other stays idle and never emits. To monitor several apps or metrics at once, give each emitter its own workflow.
