Add pluggable instrumentation and instrumentation provider capabilities to OpenJPA
----------------------------------------------------------------------------------

                 Key: OPENJPA-1739
                 URL: https://issues.apache.org/jira/browse/OPENJPA-1739
             Project: OpenJPA
          Issue Type: Improvement
          Components: instrumentation
    Affects Versions: 2.1.0
            Reporter: Jeremy Bauer
            Assignee: Jeremy Bauer


I've been working in a pluggable instrumentation framework for OpenJPA that could provide
out-of-band accessibility instrumentation of various components.  I've started with the simple
ones, DataCache & QueryCache , since they are currently instrumented (in-band).  The framework
provides pluggability of instrumentation providers and components via standard configuration.
 I have a JMX-based implementation in the works, but the framework will be designed such that
other providers and instrumentation can be plugged in as well.  The JMX provider will allow
for remote, out-of-band monitoring (and eventual control) of whatever is being instrumented.
 For example, caches, SQL execution, enhancement, etc. could be instrumented.  I'll be incrementally
committing bits and pieces of this function over the next several weeks for comment &
review.
