Handle multiline log event (stack traces) #10

Open bric3 opened 3 years ago

bric3 commented 3 years ago

Currently the code is only able to process single line log messages. However it's possible to have multiline log messages.

Scope

In particular this ticket is about handling stacktraces, which usually starts with with whitespaces. I am not familiar with stacktraces in other languages, so the goal of this ticket is to focus on Java stack traces that may appear in a log trail.

Out of scope

Multi line log messages not starting by a whitespace
Stacktraces of other than Java

This could be implemented as a normalizing step that can understand stacktrace and adds it as a metadata / placeholder.
