Review request for geode, Jinmei Liao, Jared Stewart, Kevin Duling, Ken Howe, Kirk Lund, and Swapnil Bawaskar. Repository: geode Description ------- To avoid dependency on geode-core, the pulse loggers are instantiated directly from LogManager, rather than canonical LogService (which itself extends LogManager). Significant reduction of logging level state checks, relying on Log4j handling. Significant reduction of string concatenation, relying on Log4j2 string substitutions. Reduction of logging using an exception e.getMessage, favoring instead passing the exception itself for the stacktrace. Multiple identical exception blocks collapsed. ================ Explicitly not addressed in this ticket: - A great deal of logging could do with localization. - A number of exception blocks catch one or more types of exception and only log the exception before moving. These are specific exceptions and not the general `Exception` class. The catches could be simplified, but could that lead to a catch an error that would otherwise be raised? The original ticket was not about updating from a depreciated class, but about how logs were not being collected. The answer to this was that Log4j wasn't tracking them, so they weren't being gathered; extending Log4j to do Pulse tracking should resolve the issue, but is it okay that this is only tangentally answering the problem?

Test/LegacyDUnitTest have already come back green. Testing not done: actually verifying anything involving Pulse logging. I still need to learn how pulse is used. Thanks, Patrick Rhomberg
