[DISCUSS] Monitoring Plugin to get stats through JMX or MEJB
Hi All,
There was a recent discussion on whether the monitoring plugin should
use JMX or MEJB to fetch Geronimo's statistics. Since we want to be
able to monitor any type of Geronimo server, including little-G, it is
not preferred that we have to pull in OpenEJB in order to monitor that
server. Therefore, the JMX method looks like a potential alternative,
because I do not think it will need to pull in any additional
components.
The idea of using JMX and MEJB is the same, and that is, we want to
get a hold of the MBeanServer to query that for statistics.
The concept of MEJB was defined in JSR-77, which is the only reason I
am hesitant to start migrating over to using the JMX method. Should we
strictly follow the JSR? or should we branch off and customize a
little?
Any thoughts or comments?
Regards,
Viet

I like JMX.

Um, not quite.. According to JSR77.7.1.1 JMX requirements -
"The MEJB component exposes the manageable resources on a J2EE platform
as JMX Managed Beans (MBeans) and requires an implementation of the JMX
public APIs specified by the Java Management Extensions Instrumentation
and Agent Specification, v1.1."
It could be that MEJB is well suited for writing management
tools designed to manage heavy duty servers with clustering
capabilities. JMX will be sufficient for little-G. I am OK with
switching to JMX. We MUST use JSR77 stats, i.e. use getStats() on
J2EEManagedObjects and resist the temptation to get to raw MBeans
directly.
I don't see any problem using jmx for monitoring

My impression (not based on any inside info whatsoever) is that the
MEJB was introduced largely because for some reason the jsr77 spec
team didn't want to require jmx in j2ee -- this was well before jmx
was added to j2se. I don't see any problem using jmx for monitoring
geronimo servers. If we want to be able to also monitor other
servers we could keep the MEJB-using code around for that purpose.
my opinion :-)

I agree. I think Jeff mentioned this first, for the monitoring client
to support different connectors for getting the stats. So we would
have one connector that talks JMX, another one that uses MEJB, etc.

I was recently talking to a user that was really interested in the
modular framework of the server. They really liked the idea of
jettisoning the EJB container and were also really interested in
monitoring the server. For those folks I'd suspect that JMX is the
right answer. Personally, I'd go with JMX and if someone wants to use
MEJB they should be able to.
