Trigger Function

Using the trigger function, you can automatically start/stop logging during monitoring when predefined conditions are detected.

• When a specific log is detected (Log Trigger)
• When a specific key is pressed (Key Trigger)

This lets you save logs efficiently only at required timing.

Trigger settings are configured in Trigger Window.

Trigger Modes​

Available trigger modes and behavior are as follows.

Trigger Mode	Behavior
Free Run	Disables trigger function. Logging starts/stops with monitoring start/stop.
Triggered	Enables trigger function. Logging starts/stops when configured trigger conditions are detected. If stop trigger is detected once, monitoring also stops.
ReTriggered	Enables trigger function. Logging starts/stops when configured trigger conditions are detected. When stop trigger is detected the 64th time, monitoring also stops.
