Kirk Lund updated GEODE-2644:
-----------------------------
Description:
Presently Geode adds and configures the LogWriterAppender and AlertAppender at
runtime. These appenders cannot be specified or configured within xml. This is
a request to change Geode so that these appenders can be specified and
configured in a custom log4j2.xml file.
Presently Geode dynamically creates, adds and removes AlertAppender and
LogWriterAppender by manipulating log4j2 core API. We should move the bulk of
the Appender functionality to internal classes and just leave the Appenders
registered with log4j2 during the life of the JVM.
This allows us to enable and configure our Appenders via log4j2.xml and control
the Cache-controlled lifecycle internally without having to add and remove
custom Appender instances.
The code would then become simpler, we could avoid invoking log4j2 core APIs,
and users would have control over configuring our use of log4j2 completely
within the .xml file. Presently, a user cannot configure our AlertAppender or
LogWriterAppender in log4j2.xml.

This ticket requires GEODE-1275. Right now these appenders are added and
removed by Geode when connecting or disconnecting from the DistributedSystem.
When these appenders were introduced, this behavior was required to maintain
previous behavior. If we refactor the appenders to add one more layer of
indirection between the appender and the DS lifecycle, then this internal layer
could enable/disable active appending even when the appenders are specified
within log4j2.xml.
