This topic describes how to use the function in the .

This function has been deprecated. Use the new Apply Line Break function instead.

Description

Parses data received from a universal forwarder into a stream of complete events for a Splunk Index. The universal forwarder does not parse incoming data, so you must use this function if you are using a universal forwarder. You must use merge_events in conjunction with key_by.

SPL2 examples

The following example assumes that you are in the SPL View. When working in the SPL View, you can write the function by providing the arguments in the exact order shown below.

Break a single event in body using a newline delimiter, and output multiple events in newfield.

...| merge_events content=cast(body, "string"), delimiter=/\n/, output=newfield, max_event_size=1000000 |...
