Subject [jira] Commented: (OPENJPA-1739) Add pluggable instrumentation and instrumentation provider capabilities to OpenJPA
Date Wed, 21 Jul 2010 22:59:49 GMT


Pinaki Poddar commented on OPENJPA-1739:

A very useful project.

1. Would you consider using Attach API for remote connectivity?

2. What are the candidate technologies for visualization/control widgets? At least to begin
with? Web, Swing, RCP/IDE?

3. Are you planning to create a openjpa-tools module for check-in the code contributions?
Or else?

> 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 &
