Im trying to implement a simple grok pattern based on the standard grok
patterns from the logstash repo, but I get all sorts of extra fields in my
messages. At first i was confused, but then I figured out it was the
normally discarded sub-patterns.
For example I have a grok pattern like this:
%{USER:Proto}
which uses a pattern called USER and then finally USERNAME like this:
USER%{USERNAME}
USERNAME [a-zA-Z0-9_-]+
So in my messages I have the Proto field, and the USER field. Normally if a
grok pattern doesnt have a name, it gets discarded, but in Graylog 1.0.0 it
gets the default name of the field instead. This quickly adds up ALOT of
irrelevant fields when using alot of sub-patterns. It doesnt really break
anything, but it clutters the field list with redundant and confusing
fields.
Any work-arounds?
Will this be fixed? should I create a ticket?
Brgds.
Martin
