Hello, WLS/OSB or other FMW products are logging standard messages with Error severity, Example is THREAD_DUMP dumped always during WLS shutdown sequence:


Jul 22, 2021 1:06:27,319 PM UTC> <Error> <> <BEA-000000> <THREAD DUMP from JVM taken at 'Thu Jul 22 13:06:27 2021'

Full thread dump Java HotSpot(TM) 64-Bit Server VM (25.281-b25 mixed mode):

Perhaps it could be good idea enhance the tool and add capability to ignore some errors patterns by tool.

For now I would be marking such patterns with "NO_ERROR" error label to ignore later:

error:
        - pattern: "THREAD DUMP from JVM taken"
          value: "NO_ERROR"
