Problem with using Server Perf Monitor plugin

[sathishkumar]

Hi,

when I tried to analyses the performance of a server.

Step 1: I run the server agent in Server.
Step 2: I added the server IP and port in another machine and tried to
monitor

but in the server agent command popup I get this strange error

INFO    2012-03-22 12:53:29.403 [kg.apc.p] (): Binding UDP to 4444

Could some please help me to analyze the problem. In the listening machine "Waiting for samples" is the only message I get.

That's frequent user error. You're trying to connect to new perfmon 5.1 with old JMeter Plugin version. Upgrade your JMeter Plugins installations.

Hi Andrey,

Thanks alot but still I face the issue with the plugin

I installed latest Jmeter (version 2.6) and Jmeter Plugin version (JMeterPlugins-0.5.1).

Tried the same scenario but still I face the problem. The server agent popup showed the below message.

INFO    2012-03-22 14:10:39.368 [kg.apc.p] (): Binding UDP to 4444
INFO    2012-03-22 14:10:40.382 [kg.apc.p] (): Binding TCP to 4444
INFO    2012-03-22 14:12:25.871 [kg.apc.p] (): Connecting new UDP client
INFO    2012-03-22 14:12:25.886 [kg.apc.p] (): Yep, we received the 'test' command

INFO    2012-03-22 14:12:25.995 [kg.apc.p] (): Client disconnected


The JMeter still shows "Waiting for samples" message.

Try starting the agent with --udp-port=0 switch, this will make it using TCP only

Can you please tell me how can I do it??

[Andrey Pohilko]

:) OMG, command-line switch, dude! http://en.wikipedia.org/wiki/Command-line_interface#Arguments
