Hi,
This is happen when monitoring the java process via java gateway.
thanks,

Not sure but look like a communication problem.
If you have firewalls between then that could be the problem.
As I remember the communication require more then on port - and at least one is dynamic allocated.
Yes now I found the post - look in post #5:

Is possible to connect java gateway with JVM directly?

thank you very much for the reply.

I need to monitor all the java process running locally. So I don't want to specify any port number in JMX interface of that host. Is this possible?
or it is possible to connect zabbix agent with zabbix java gateway?

Thanks
