The search below groups events by two or more fields (clientip and host), creates transactions with start and end constraints (maxspan=30s and maxpause=5s), and calculates the duration of each transaction.
index=main | transaction clientip host maxspan=30s maxpause=5s
The search does the following:
* It filters the events by the index main, which is a default index in Splunk that contains all data that is not sent to other indexes.
* It uses the transaction command to group events into transactions based on two fields: clientip and host.
The transaction command creates new events from groups of events that share the same clientip and host values.
* It specifies the start and end constraints for the transactions using the maxspan and maxpause arguments. The maxspan argument sets the maximum time span between the first and last events in a transaction. The maxpause argument sets the maximum time span between any two consecutive events in a transaction. In this case, the maxspan is 30 seconds and the maxpause is 5 seconds, meaning that any transaction that has a longer time span or pause will be split into multiple transactions.
* It creates some additional fields for each transaction, such as duration, eventcount, startime, etc. The
* duration field shows the time span between the first and last events in a transaction.
