What will you learn from the results of the following search? sourcetype=cisco_esa | transaction mid, dcid, icid | timechart avg(duration)

The transaction command groups events sharing mid, dcid, and icid values into single transaction events and calculates the 'duration' field as the time span from first to last event in each transaction; timechart avg(duration) then plots the mean of those elapsed times across the time axis.

The search does not show time for individual events within transactions; duration represents the span of the entire transaction, not per-event timing.

The search measures time elapsed within transactions, not the time gaps between separate transactions; inter-transaction timing would require a different approach such as using streamstats.
