Question 2
Which of the following statements describes this search?
sourcetype=access_combined I transaction JSESSIONID | timechart avg (duration)
This is a valid search and will display a timechart of the average duration, of each transaction event.
This is a valid search and will display a stats table showing the maximum pause among transactions.
No results will be returned because the transaction command must include the startswith and endswith options.
No results will be returned because the transaction command must be the last command used in the search pipeline.
Correct 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 startswith and endswith 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.
