Please help me how to resolve this.

I also tried with (http://jmeter-plugins.org/wiki/PerfMonAgent/)

also http://jmeter-plugins.org/wiki/PluginInstall/

But no use

[Andrey Pohilko]

Hi,

It seems you have configured your PerfMon Collector to connect to port 3450, while server Agent binding on port 4444. Those ports must be the same for the process to function properly.

No I am not configured wrongly. I tried both portds and both were not working

[Andrey Pohilko]

So there may be some firewall issue. The fastest way to check for firewall issue is to run "telnet 9.12.207.128 4444" from JMeter machine. It should connect and answer "Yep" if you type him "test".

Post here the results for telnet check.

Hi Audrey, I am having the same issue. when I ran telnet 9.12.207.128 4444 from cmd it says "could not open connection to the host", on port:4444, connect failed

[Andrey Pohilko]

So this is firewall issue. Consult with your network administrator.

Hi Xiaojuan,

     Whether this issue got resolved in your environment? Even I am also facing the same issue in my environment

Thanks,

Hi,
Documentation :
http://jmeter-plugins.org/wiki/PerfMonAgent/
Extract :

Server Agent uses simple plain-text protocol, anyone can use agent's capabilities implementing client, based on kg.apc.perfmon.client.Transport interface. If anyone's interested, start the topic on the support forums and I'll describe how to connect third-party client app to agent.

ServerAgent has simple text protocol and can work on UDP and TCP transports. Most of cases will use TCP.

To have your first talk with the agent, start it locally. Then use telnet utility to connect to it:

user@ubuntu:~$ telnet localhost 4444
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.

If connection has succeeded, you should see "Accepting new TCP connection" message in ServerAgent console log. Type "test" and press Enter in telnet chat, server should answer with short "Yep":

test
Yep

Type "exit":

exit
Connection closed by foreign host.

Regards.

A well-behaved server agent installation should look like:

See How to Monitor Your Server Health & Performance During a JMeter Load Test for comprehensive installation and troubleshooting instructions.

Hi Vincent,

I 'm able to connect to agent through telnet, but the Jmeter plugin throws the unreachable via TCP error. SSH tunneling is being used to connect to the server where agent is running as I don't have direct access to the server. See that the agent receives the TCP connection, a test command and immediately closes the connection. Any idea what is getting wrong here ?

Thanks

Hi colleagues.

I have the same issue with JMeter Perfmon. I can connect 4444 port using telnet command but at the moment I see ERROR: java.io.IOException: Agent is unreachable via TCP. 

Best regards, Aliaksandr

I had the the same issue but when I looked at the Agents creation one of my agent's port was set to XXXX instead of 4444, I changed it back to 4444 and it worked for me :)

[go2r...@gmail.com]

Can you please elaborate what steps you did ?

[Aliaksandr Kavaliou]

Thank you for the response. Actually, after some magic restarts of JMeter and server agent the problem had gone.

Apologies for keeping silent about the issue resolving.

 

Kind regards,

Hi , i am able to start my agent and telnet as weel from server where my jmeter is runnning

bash-4.1$ ./startAgent.sh --udp-port 0 --tcp-port 3450

Hi,

Does your JMeter test has any requests in it? Monitoring will work only if your test has any duration.

Yes Andrey

My Apologies, its always a port issue!! Thanks for replying!! Again my bad to waste your time.

[pramo...@gmail.com]

We got this issue and resolved by Load balancer issues...there were issues in firewall.

[itikamal...@gmail.com]

Hi!

I am facing the same issue. Can u please help me to resolve this ASAP.

[andres.g...@avature.net]

I faced the same error. The problem is that sadly the perfmon agent has a hardcoded timeout value of 500 ms (https://github.com/undera/perfmon-agent/blob/master/src/kg/apc/perfmon/client/TransportFactory.java#104).

I had to download the code, change this value, compile the package, copy the binary in the jmeter library and restart jmeter. Then it worked.

Regards
