Hi Chad,
I had a similar issue for which I found a solution: I think the reason for
your non-match is that regex() needs the pattern to match fully on the
message string. Try to modify your pattern to something like "^.+SomeProc
*.**".
*@ Jochen:* Could you comment on that? I think the reason is that
org.graylog.plugins.pipelineprocessor.functions.strings.RegexMatcher uses
Matcher.matches() which, according to javadoc, "Attempts to match the *entire
region* against the pattern." From my point of view, regex() should comply
to a standard behavior where /^foo/ matches "foobar", not requiring /^foo.*/.
Actually, I already wanted to file an issue but am afraid of rejection. ;-)
Best regards
tokred
