Subject [jira] Commented: (GERONIMO-3586) monitoring plugin: collecting agent should have separate jetty and tomcat plugins
Date Wed, 07 Nov 2007 15:24:50 GMT

Joe Bohn commented on GERONIMO-3586:
------------------------------------

IIUC the client is actually running on a particular server and hence a particular container.
 The client can only retrieve information for that container.  Therefore, it provides no value
for a client to have extraneous interfaces available to it for another container.  

It is the monitoring console  (also running on a particular server/container) that is the
integration point for multiple containers.  However, the monitoring console itself does not
access the stats directly.   

So it would seem to me that a monitoring client is by design always limited to one container
and it provides no value to have excess interfaces available for another container.  I won't
press the point much further, but I still don't see value in the client having access to interfaces
that it cannot utilize.  So it makes sense to me that we consolidate the container specific
classes under the container plugin (the intent behind GERONIMO-3587).

> The collecting agent plugin needs to have separate jetty and tomcat plugins in order
to accommodate for the differences in container specific dependencies on stats implementation
(.e.g JettyContainerStatsImpl and JettyConnectorStatsImpl). When the collecting agent was
an EAR, this was not a problem; however, as a plugin, it is more tied down to having to specify
all dependencies in the plugin's classpath.
