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.
