Yes, we don't currently have any JMX monitoring in Jersey. There is
some basic monitoring supported with GlassFish, using GlassFish
probes, and one can get simple statistics of hits on resource classes/
methods.
Quite a bit of information can be obtained from the HTTP/servlet layer
given that when HTTP is used as an application protocol if provides
much richer information that if used just as a transport, and as Jan
points out much of that information can also be obtained by an
intermediary. For a framework like JAX-RS it does not make sense to
duplicate that and instead concentrate on monitoring of the
application components e.g. to ask questions like why the heck is
processing a GET request to this method of this class taking 10x
longer than we expect? or to tell correlate URI states with
application artifacts.
I would be interested in feedback from people on what they would like
to see in terms on monitoring in Jersey, using JMX or otherwise.
