Trigger Function

The trigger feature lets you automatically start and stop logging when the conditions you configure are detected during monitoring:

• Detect a specific log entry (log trigger)
• Press a specific key (key trigger)

Configure triggers in Trigger Window.

Trigger Modes​

Mode	Behavior
Free Run	Disables triggers. Logging follows the manual start/stop of monitoring.
Triggered	Enables triggers. Logging starts/stops when the configured conditions are detected. Monitoring stops the first time a stop trigger occurs.
ReTriggered	Enables triggers. Logging starts/stops when the configured conditions are detected. Monitoring stops when a stop trigger occurs 64 times.
