Splunk knows where to break the event, where the time stamp is located and how to automatically create field value pairs using the source type. Splunk uses source type to categorize the type of data being indexed; In most production environments, forwarder will be used as the source of data input.

Line breaking, which uses the LINE_BREAKER attribute regular expression value to split the incoming stream of bytes into separate lines.
While I was reading we ran into the question “What is the difference between line breaking and merging in Splunk?”.
Line breaking is relatively efficient for the Splunk platform, while line merging is relatively slow. Using the LINE_BREAKER setting can produce the results you want in the line breaking phase. This is valuable if a significant amount of your data consists of multiline events.
Splunk tags are descriptive names for?
Tags are used to assign names to specific field and value combinations. These fields can be event type, host, source, or source type, etc. You can also use a tag to group a set of field values together, so that you can search for them with one command.
