Failed to get JMX Connector

[Abdul Moid]

Hi,

I have 0.5.2 version running. I am connecting to my Test Server Box where Server agent is running at port 4444.

I have added the JMX metric and i am looking to collect gc-time metric, But unfortunately i am getting Failed to get JMX connector exception.

192.168.16.223    4444    CPU    combined
192.168.16.223    4444    JMX    gc-time

I am getting CPU combined metrics but i am not getting gc-time JMX metric.

I also tried to change the port to 1099, but when i change to 1099 test plan never started.

Following are the logs when i am connecting via port 4444:

Please do let me know what i am doing wrong here Pleaseeeee

You should know that serverAgent port is different from JMX port. 

Point 1: your Java application must be started with special options to open its JMX port.

Point 2: `gc-time` may be not enough to setup access to JMX port from serveragent. See help for possible configuration options.

The scheme is like this: computer A with JMeter, server B is target, server C is server with JMX-enabled application running. Yes, for sure, hosts B and C in most cases are the same. But serverAgent needs to be sure and requires proper configuration.

Hope this helps.

Thanks,

Problem is now solved i was specifying the metric details wrongly.

192.168.16.223    4444    JMX    url=192.168.16.223\:1099:gc-time

now i am getting all the JMX related metrics.

One quick question, is it possible i can monitor the JMX queues ?
