How we do websocket testing using jmeter? When I tried to run the request than it get failed.

It looks like WebSocket Sampler cannot establish the connection with the server:
given you use wss protocol my expectation is that you need to use port 443 in the "Port number"
You may also find JMeter WebSocket Samplers plugin easier to use, it's more up-to-date, powerful and convenient, see JMeter WebSocket Samplers - A Practical Guide for more details.

How to use existing websocket connection to another websocket request in jmeter?
When I tried to use existing connect then as result it show me an error "Sampler configured for using existing connection, but there is no connection" . Please refer attached screenshot.

It looks like you're using 2 different WebSocket Samplers implementations:
JMeter-WebSocketSampler
and JMeter WebSocket Samplers
Your WebSocket Single Write Sampler:
Doesn't know anything about the connection established by the WebSocket Sampler
The WebSocket Sampler closes the connection after receiving the response
So if you want to continue with the WebSocket Single Write Sampler you need to:
Use WebSocket Open Connection sampler to establish the connection:
In the WebSocket Single Write Sampler tick use existing connection box
More information: JMeter WebSocket Samplers - A Practical Guide
If you want to continue with the WebSocket Sampler - tick Streaming connection box:
and remove the WebSocket Single Write Sampler and friends from the Test Plan
Hi I am doing performance testing over a application but i cannot replicate the signalR connection what i do is call to the negociate api
/signalr/negociate getting the response as expected with the connection token
"Url":"/MyApp/signalr","ConnectionToken":"gM8NUnZtDg6oYU3Y9sfZgnIDlInyvspePwDuRdmqZlslRgkPIp8w/c0FZzllhwiUdZlOmPkyBd2DGU76ldt3v1B25lQlTeg1jETBWRkqaXD0QGpeNJLl3KqvnJ3v4YQ2","ConnectionId":"e1adc41d-ad0d-439f-858c-1fa47bb59083","KeepAliveTimeout":20.0,"DisconnectTimeout":30.0,"ConnectionTimeout":110.0,"TryWebSockets":true,"ProtocolVersion":"1.5","TransportConnectTimeout":5.0,"LongPollDelay":0.0}
Then i extract with JMeter that token (and i use it into the connect call)
GET https://myHost/myApp/signalr/connect?transport=webSockets&clientProtocol=1.5&connectionToken=gM8NUnZtDg6oYU3Y9sfZgnIDlInyvspePwDuRdmqZlslRgkPIp8w%2Fc0FZzllhwiUdZlOmPkyBd2DGU76ldt3v1B25lQlTeg1jETBWRkqaXD0QGpeNJLl3KqvnJ3v4YQ2&connectionData=%5B%7B%22name%22%3A%22workhub%22%7D%5D&tid=2
But the response is always a 400 Bad Request
Not a valid web socket request.
Any idea why that call fail?
Thank you very much
I don't think you can record WebSocket requests using JMeter's HTTP(S) Test Script Recorder as the aforementioned HTTP(S) Test Script Recorder is only capable of generating HTTP Request samplers as of JMeter 5.2
I would recommend using one of the following approaches for capturing outgoing WebSocket requests:
Browser developer tools (network tab should have WebSocket traffic filtering option)
Fiddler
Wireshark
Once done you can install JMeter WebSocket Samplers plugin and use the appropriate Samplers to simulate the WebSocket requests, you will need to manually set up the payload.
I am recording our game app using JMeter
And it has an API server, which using the WebSocket's protocol
While meeting that request sent to API server, I always get this message, and can't go further
Is that means I need to modify the original JMeter's source code to walk around this problem? Or any way out? If so, that'd be appreciated.
I don't think you will be able to record and replay WebSocket transport using JMeter's HTTP(S) Test Script Recorder as WebSocket is a different beast, given you have a game application my expectation is that it might be the case application opens a WebSocket connection and re-uses it until the end of session and so you won't be able to mimic this behavior using "normal" HTTP Request samplers as WebSocket assumes either ws or wss protocol.
I would suggest considering one of the following JMeter Plugins:
WebSocket Sampler by Maciej Zaleski
WebSocket Samplers by Peter Doornbosch
Both plugins can be installed using JMeter Plugins Manager:
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.
we have an application (client/server) which uses a GUI to communicates to the Tuxedo server. it uses TCP, FTP protocols for communication. can we use JMeter or any other open source tool for that?
JMeter does support both FTP and TCP protocol via FTP Request and TCP Sampler elements provided, so the answer is "yes", you can use JMeter.
You can also find How to Send Control Characters Using the JMeter TCP Sampler guide useful as it's rather common problem and frequently asked question.
However I doubt that JMeter can record TCP-based traffic types. You can try pointing your client application to server via JMeter HTTP Proxy server to see what requests it'll catch.
