Chapter 1 Configuring Threat Detection
Configuring Advanced Threat Detection Statistics
The ASA stores the count at the end of each burst period, for a total of 30 completed burst intervals. The
unfinished burst interval presently occurring is not included in the average rate. For example, if the
average rate interval is 20 minutes, then the burst interval is 20 seconds. If the last burst interval was
from 3:00:00 to 3:00:20, and you use the show command at 3:00:25, then the last 5 seconds are not
included in the output.
The only exception to this rule is if the number of events in the unfinished burst interval already exceeds
the number of events in the oldest burst interval (#1 of 30) when calculating the total events. In that case,
the ASA calculates the total events as the last 29 complete intervals, plus the events so far in the
unfinished burst interval. This exception lets you monitor a large increase in events in real time.
