Which of the following statements describes this search?

sourcetype=access_combined I transaction JSESSIONID | timechart avg (duration)
A . This is a valid search and will display a timechart of the average duration, of each transaction event.
B . This is a valid search and will display a stats table showing the maximum pause among transactions.
C . No results will be returned because the transaction command must include the startswith and endswith options.
D . No results will be returned because the transaction command must be the last command used in the search pipeline.

Answer: A

Explanation:

This search uses the transaction command to group events that share a common value for JSESSIONID into transactions1. The transaction command assigns a duration field to each transaction, which is the difference between the latest and earliest timestamps of the events in the transaction1. The search then uses the timechart command to create a time-series chart of the average duration of each transaction1. Therefore, option A is correct because it describes the search accurately. Option B is incorrect because the search does not use the stats command or the pause field. Option C is incorrect because the transaction command does not require the starts with and ends with options, although they can be used to specify how to identify the beginning and end of a transaction1. Option D is incorrect because the transaction command does not have to be the last command in the search pipeline, although it is often used near the end of a search1.
