Restart
The Restart button causes the two counters Count1 and Count2 to be reset
to zero. It also causes the search for event sequences to restart. Event
sequences are sequences of events that trigger the end of the recording.
Restart buttons provide you with a way of saying "If you see a sequence of
A, B, C, and D, then trigger. However, if you see X anywhere during the
sequence, restart your search."
Count1, Count2
Count1 and Count2 are counters for specifying how many events must occur
before an event can cause a trigger. Counters allow conditions to be made
such as "Trigger after the 21st Poll packet" (see screenshot below).
The Actions window showing a condition based on a Poll packet and a
counter. This condition reads "Trigger after the 21st Poll packet."
Connecting Events to Counters
To connect an event to a counter, click an Event button, then click one of the
two counter buttons. The Counter will reposition itself immediately below
the event. A line will the connect the counter to the Trigger button.
This latter connection between the Counter button and the Trigger button
occurs because counters always work in association with triggers. Counters
act as assistants to triggers.
Setting Multiple Conditions with Counters
You can create multiple event conditions by linking a counter to multiple
events or by linking two counters to two or more events.
