Explanation:

Thetransactioncommand is a Splunk command that finds transactions based on events that meet various constraints1.

Transactions are made up of the raw text (the _raw field) of each member, the time and date fields of the earliest member, as well as the union of all other fields of each member1.

Thetransactioncommand adds some fields to the raw events that are part of the transaction12. These fields are:

duration: The difference, in seconds, between the timestamps for the first and last events in the transaction12.

eventcount: The number of events in the transaction12.

closed_txn: A Boolean field that indicates whether the transaction is closed or evicted2.A transaction is closed if it meets one of the following conditions:maxevents,maxpause,maxspan, orstartswith2.A transaction is evicted if it does not meet any of these conditions and exceeds the memory limit specified bymaxopentxnormaxopenevents23.

Therefore, evicted transactions can be distinguished from non-evicted transactions by checking the value of theclosed_txnfield.Theclosed_txnfield is set to0, or false, for evicted transactions and1, or true for non-evicted, or closed, transactions23.
