Is my karaf server fully started ?
Hi,
Sorry if the subject has already been treated, I searched in the historic
but didn't find a complete answer...
*I'm looking for a way to determine if my karaf server is fully started (i.e
all my routes operational).*
I've been adviced to build a special "log-route" just to indicate "your
server is started" and to raise its start-level to 99 (all others routes are
@start-level=80). Thus, when "your server is started" appears in karaf log,
the server is censed to be fully operational.
But most of my other complex routes take almost a whole minute to start, and
even if the log-route begin its start after the others, the finish_log
appears before the others routes have finished their startup.
How is it possible to indicate to my log-route to begin its start AFTER the
end of all other routes startup ?
Or is there another way to be sure that all routes are fully active ?
Thank you for your ideas :-)

Or alternatively you can also write an little OSGi bundle that talks
directly to the MBean Server via
ManagementFactory.getPlatformMBeanServer() and does whatever it wants
to do when the desired state has been reached.
BTW do note that when using this with Karaf 3 you need to provide
login credentials.
Cheers,
David

Hi Pierre,
The JMX client can be "hardcoded", but you have a bunch of monitoring
solution that provide JMX client (nagios, zabbix, etc).
Eventually, you can install jolokia in Karaf (just install the
jolokia-osgi bundle): it will "wrap" the MBeans with REST services. So
you need a simple HTTP/REST client in that case.
Regards
JB

Thank you for your answer Jean-Baptiste,
I'm going to dig in that direction with a JMX Client and I'll be back here
for feedbacks :)
Best regards,
Pierre.

Hi,
why not simply use the MBeans with a JMX client ?
You can check the status of the different routes, features, bundles, etc.
So you can check the status of Karaf and the deployed applications.
