Hi,

it seems that Mina JMX instrumentation is planned, but I don't know when.

I actually need some performance counters (throughput, total nr of connectio
ns,
current and max nr of concurrent connections...) for an application based on
Mina.

I am going to spend some time on this, and I could do it in Mina code as wel
l,
so that everyone can benefit.

But I would need feedback on needed counters and some help for the best plac
es
to probe.

What do you think of this ?

That's sound very interesting 
I'm working on implementing a fail-over service and replication on my
MINA bassed server, and I need to monitor some parameters (different
MINA Protocol stacks status, CPU usage , free RAM and dozen of custom
parameters) for triggering a service migration (killing the running
service on the main server and start the service on the backup server).

I'm really new to JMX instrumentation but i think it could really help
me, so I'm willing to help to get it into Mina.

JMX is really simple, as you will notice.

I need counters providing qualitative and quantitative information
about server
load.

A first good data would be the time a SessionManager is idle (blocked on
Selector.select()). Then, workTime = lifeTime - idleTime (I don't know if
vocabulary is the more appropriate one) This workTime is valuable for
statistics.

Hi, Jean-Francois,

Wow, thank you so much for your great plan.

JMX integration is planned to be included in version 1.1:

http://issues.apache.org/jira/browse/DIRMINA-29

We could keep talking about it there by leaving comments. I'll start
enumerating the requirements.

Thanks,
Trustin
