I agree with Lily.
I just started using OtrosLogviewer and wanted to split the custom .pattern file needed to parse GF logs. The following .pattern file works for GF 2.1.1 logs:
type=log4j
customLevels=SEVERE=FATAL,WARNING=WARN,CONFIG=INFO,FINE=DEBUG,FINER=TRACE,FINEST=TRACE,INFO=INFO
pattern=[
dateFormat=yyyy-MM-dd'T'HH:mm:ss.SSSZZZZ
name=Glassfish Logfile
charset=UTF-8
The dump is higher in the file glassfish.patternin the Otros installation folder $olv-home\plugins\logimporters\.
