Take a look at Ostrich Integration
Imtiaz has just sent me first results of his Ostrich (
http://github.com/robey/ostrich) integration (see below). This means
that we now have a JSON-based way to access our JMX data. Why is this
important - developers can now develop web-based tools to track
various critical measures / metrics in ESME. We had JMX implemented
before but the problem was that we could just use the JMX interfaces
(MBean, etc.) - now developers can create their own mash-ups to
administer / track ESME events. Better still, it looks like we can
use port 80 which means that we could use Ostrich in the Stax
environment (still have to try this when I deploy on Monday).
Here is a list of our current metrics
(http://incubator.apache.org/esme/jmx.html).
I'll do a commit of Imtiaz's code on Monday.

Re: Take a look at Ostrich Integration
Posted by Richard Hirsch <hi...@gmail.com>.
This is now implemented and committed.
The problem is that ports used by ostrich can't be the same ones used
by the web-server. Thus, the solution can't be used in the Stax.net
environment, because we just have one port (80) that is available and
it is used by the web-server (lift). If you try to use the same ports,
then ESME doesn't work correctly.
Works fine locally and in other environments where more ports are allowed.

Re: Take a look at Ostrich Integration
Posted by Vassil Dichev <vd...@apache.org>.
I think there's a slight misunderstanding- the code which Imtiaz
developed is going to be applied as a patch attached to ESME-161 in
Jira (https://issues.apache.org/jira/browse/ESME-161) and the code in
github is a library used as a dependency. It is actually the successor
to the scala-stats library, which we have already been using. We have
already checked the library's license (which hasn't changed) and the
licenses of its dependencies before last release, so I think we're
still covered.

Re: Take a look at Ostrich Integration
Posted by Joe Schaefer <jo...@yahoo.com>.
Be sure Imtiaz or whomever developed the code
formally assents to their code being committed
to esme. Specifically in the commit log message
call out the fact that Imtiaz developed the
code, and post-commit have him send an email here
saying "I have read and approved r952... ".
The reason you should do this is that pulling code
from github isn't covered by the Apache License's
contribution clauses (unlike posting patches to
apache's jira or mailing lists), so either an ICLA
is called for from the author, or something a bit
less heavyweight like I have described.
