How to fix wire format negotiation timeout issue in JMeter when sending messages with JMS Point-to-Point sampler?
I have gone through the probable causes provided by apache at this link - http://activemq.apache.org/javaxjmsjmsexception-wire-format-negociation-timeout-peer-did-not-send-his-wire-format.html - no luck.
Here is the error message:
jmeter.protocol.jms.sampler.JMSSampler: Wire format negotiation timeout: peer did not send his wire format. javax.jms.JMSException: Wire format negotiation timeout: peer did not send his wire format.at rg.apache.activemq.util.JMSExceptionSupport.create(JMSExceptionSupport.java:62)
Same properties if set in LoadRunner, I am able to send messages successfully using Java over HTTP protocol.
I also monitored network using netstat when running JMeter and LoadRunner.
What I could see is JMeter connection always goes to 'CLOSE_WAIT' status whereas Loadrunner connection goes to 'SYN_SENT' 'ESTABLISHED' - as expected.
I have added keystore and ciphersuite to system.properties and can see keystore created OK in JMeter logs but nothing specific for ciperhsuite.
Could that be the issue?
Been stuck with this exception for about a week now, any help is highly appreciated.

I want to set MQTT connect as a Jmeter property and use this connection in other thread which will post messages concurrently to MQTT broker. What I want to implement is
Set MQTT connect as Jmeter property
1 thread which will use the connection to post messages to MQTT broker
MQTT disconnect
What I have done so far is using MQTT connect, Publish samplers and MQTT disconnect in same thread group. But when running multiple threads messages are getting failed to publish for other than thread-1.
Please let me know if there is any way to implement this.
I don't think that:
Moving the connection into another Thread Group
Trying to publish messages concurrently with multiple virtual users over a single connection
is a good idea because well-behaved JMeter test must represent real life usage of your application and each JMeter thread (virtual user) must represent an MQTT-enabled device which establishes its own connection to the broker. If the "messages are getting failed to publish" it indicates problem either with your test setup (parameterization, correlation, whatever) or with your MQTT broker so first of all I would check:
whether all JMeter Variables are having expected values
jmeter.log file
your MQTT broker log file
your system under test log file
See Testing the MQTT Messaging Broker for IoT - A Guide article for more details.
If you're still looking for a way of passing the MQTT connection between thread groups you can do this using JSR223 Test Elements and the following code:
To save the connection into a property:
props.put('connection', vars.getObject('conn'))
To get the connection object from the property:
vars.putObject('conn', props.get('connection'))
During I use the Jmeter Websocket request-response Sampler plugin to do the load test, the server returns the following errors:
(1)Sampler error: unexpected frame type (ping).
(2)Ping frame with application data 'T悅o'
But how can I check out the error and find the solution to the problems, thanks for your help:
Responses from the WebSocket server
You can add WebSocket Ping/Pong Frame Filter to your Test Plan and it will automatically discard Ping and/or Pong frames so you should stop seeing this error.
More information:
JMeter WebSocket Samplers documentation (look for Filters)
JMeter WebSocket Samplers - A Practical Guide
I am using a plugin (WebSocket Samplers by Peter Doornbosch) to establish the WebSocket connection in JMeter and trying to send the request message over it but receiving below error in logs
ERROR - eu.luminis.jmeter.wssampler.RequestResponseWebSocketSampler: Unexpected frame type received in sampler 'WebSocket request-response Sampler': Close frame with status code null and close reason 'null'
My test plan consists of "WebSocket Open Connection", "Web-socket request-response sampler" and "web-socket ping/pong frame filter". And I feel there is no issue in establishing the connection but something is wrong while sending the request or receiving a response.
Also, tried checking the logs from the server but didn't find any requests which were sent using JMeter.
Implemented another available plugin too in Jmeter to test the WebSocket but seeing similar behavior. Any help would be highly appreciated.
It looks like you're using the wrong sampler type, looking into the error you're getting it makes more sense to use single-write sampler which is designed for sending one (text or binary) WebSocket frame.
You might want to use a sniffer tool like Fiddler or Wireshark to capture the traffic between your browser (or application) and the backend and see what types of frames are going, which direction, is single connection re-used or each time new one is established, etc.

JMeter WebSocket Samplers - A Practical Guide
The problem is that your server is actively closing the connection. Usually, this is caused by the client sending a request that the server does not understand. In your case, it's very likely that the request you are sending in the request-response sampler is not accepted by the server. As Dmitri suggests, the best way to find out how a "normal" client communicates with the server is to capture a session with WireShark and model your testplan accordingly.
Hth.
Using JMeter, the HTTP Request is hitting a URL with the port.
Eg : apitesting.com:8888/api/series/one
I have also added a HTTP Test Script Recorder in JMeter, where I can mention the port and domain.
How do I import the incoming traffic to JMeter using tcpreplay and JMeter Proxy for the above example.
Thanks for your help in Advance.
Have you read the FAQ?
Does tcpreplay support sending traffic to a server?
If by server you mean a daemon (Unix) or service (Windows) which listens on a port (a web or mail server would be common examples), then probably not. The biggest issue is that tcpreplay doesn't understand the state of common protocols like TCP. This means it is unable to synchronize Syn/Ack's to create valid TCP sessions.
So you have the following options:
Consider using Wireplay tool instead
Convert your .pcap file into JMeter .jmx script using BlazeMeter JMX Converter
In both cases be aware that you will get only a "skeleton" of the project, you won't be able to replay production traffic, all you will get would be a set of HTTP Request samplers, you will have to figure out the workload model on your own.
In JMeter you can add to your HTTP request a Post Processor Named Response Assertion, If you check the Ignore Status checkbox you will ignore response of the server so even if server is down it'll not fail test and continue.
I installed websocket stomp sampler plugin to Jmeter, and new a stomp sampler to test the server. but when I filled the connect message as the message
I got from the developer:
CONNECT
accept-version:1.1,1.0
heart-beat:10000,10000
host: qa.so.aws.mxj.mx
^#
The Jmeter gave 400 error and said
"- Connect or Subscribe Paylod Message are empty"
When I saw the request from Jmeter, it said:
["CONNECT\n\n\u0000"]
I don't know how to let Jmeter to get the correct connect message, please help me with this problem.
Try by giving both Connect Message and subscribe message.
Example:
Connect Message
CONNECT\naccept-version:1.1\nheart-beat:0,0
Subscribe Message
SUBSCRIBE\nid:sub-0\ndestination:/topic/queue
Select both the check boxes Streaming connection and stomp protocol along with other details (host, port, protocol, path, connection and response timeout).
