I have been trying with no luck today to do a structured field extraction using the "Add Data" function of my test environment:
Splunk Version 6.3.1
The data looks something like this:
2016-01-11 08:22:11.048 +10:00|SDLC||someuniquedata|Appname|ver|11|Information| Single line message
2016-01-11 08:22:12.249 +10:00|SDLC||someuniquedata|Appname|ver|11|Warning| multi-line message part 1
multi-line message part 2
multi-line message part 3
2016-01-11 08:22:26.227 +10:00|SDLC||someuniquedata|Appname|ver|48|Information| Single line message
But when I configure the parameters to do a PSV field extraction, the multiline message part 2 and 3 lines are created as separate events. At this point, since I have used many combinations of SHOULD_LINEMERGE ( and dependent config options such as BREAK_ONLY_*) and LINE_BREAK to no avail, I am left with the sinking feeling that this is just the way this type of structured data is handled...
Is there something else (perhaps outside of the gui) that I could try?
