I receive some response headers:
Connection: Upgrade
Sec-WebSocket-Accept: zi1DDwu1UMCCUC1nJX/k65L6jfQ=
Upgrade: websocket
as a result of web socket open connection
response header of websocket open connectiob
and now need to pass it to the request headers of the request response sampler as right now in the above image
request header of response sampler
there are no request headers shown
but for HTTP request it is coming (check for request header of HTTP request
I tried passing the values to the header manager but it is not passing to websocket sampler they are passing for only HTTP request.
I want that request headers to be passed to the web socket request response sampler
You don't need to do anything.
The WebSocket Samplers plugin by Peter Doornbosch automatically handles Sec-WebSocket-Key and Sec-WebSocket-Accept headers, moreover it even checks that the latter one has its anticipated value.
You can see the outgoing headers by either using a sniffer tool like Fiddler or Wireshark or enabling debug logging for the WebSocket Samplers plugin by adding the next line to log4j2.xml file:
<Logger name="eu.luminis" level="debug" />
JMeter restart will be required to pick up the change, once done you will be able to see request and response details in jmeter.log file

i have asked some questions about this and not resolved yet. i realized a new and important issue.
i listened the network by using browser and wirehark and saw that if a signalr/connect request is sent, the server does not return an http response. it sends some tcp responses and then client sends a signalr/start.
this sample is taken from browser test:
in Jmeter, after sending the signalr/connect request, jmeter waits an http response. and naturally server doesnt send this reesponse. i want to send the signalr/connect request, but not wait for an http response. how to do this?
If you want to use HTTP Request sampler - just add some small response timeout (i.e. below 1000 milliseconds), the setting lives at "Advanced" tab:
The sampler will send the request and fail in 100 milliseconds with java.net.SocketTimeoutException: Read timed out
If you don't want this failure to appear in the test results as the failure - add a Response Assertion configured as follows:
This way JMeter will send the response, disconnect in 100 milliseconds and will mark the sampler as passed.

The left in the flowing picture are the requests the websocket server got while the right are the requests the jmeter websocket send , I just don't make sure which the request client sent corresponds to the request received by the websocket server.Thanks for your help.
If you need to correlate Samplers from JMeter with your application logs you can use Sec-WebSocket-Key header for the request and Sec-WebSocket-Accept for the response.
The headers can be observed in jmeter.log file if you enable debug logging for the JMeter WebSocket plugin by adding the next line to log4j2.xml file:
<Logger name="eu.luminis" level="debug" />
JMeter restart will be required in order to pick up the changes. This is what you can get:
I have used the websocket open connection sampler request in my project.
URL: wss://sip-qa.forestreettelco.com:11443
while executing the jmeter script getting the Response message:"http upgrade failed with status code 400"
Please help me.enter image description here
As per HTTP Status Code 400 description
The HyperText Transfer Protocol (HTTP) 400 Bad Request response status code indicates that the server cannot or will not process the request due to something that is perceived to be a client error (e.g., malformed request syntax, invalid request message framing, or deceptive request routing).
So my expectation is that you're sending the wrong request which doesn't match what your server expects. As it is not publicly available I cannot come up with the proper configuration, however I believe you should start with normal HTTP Request sampler and add the following Headers to the request:
Connection: Upgrade
Upgrade: websocket
Whatever other headers which real browser sends like Sec-WebSocket-Protocol, Sec-WebSocket-Version, Sec-WebSocket-Key, etc.
The headers can be added using HTTP Header Manager
You can capture browser traffic using built-in browser developer tools or an external sniffer tool like Wireshark.
Once you will be sending the same sequence of the same requests you should get the same responses as for the real browser.
I am using jmeter plugin (WebSocket Samplers by Peter Doornbosch) for creating websocket requests manually.
Opening the connection to websocket
I use "Websocket Open Connection" sampler.
Fill all details (server,port,path)
The connection also requires sessionID.
I tried http header manager but it doesn't takes up the header while execution.
SO, is there a way to manually add websocket header to the (Websocket open connection) sampler?
Http Header Manager is the way to go; the sampler picks up all the headers, except the ones that are used by the WebSocket or HTTP protocol itself (e.g. "Host", "Sec-WebSocket-Key"). If your header is called "sessionID", it definitely should work. See also the "Basic request-response sample with Header and Cookie Manager.jmx" example in the samples directory (https://bitbucket.org/pjtr/jmeter-websocket-samplers/src/master/samples/)
Are you 100% sure the sampler did not include the header? Did you check the HTTP GET request with a tool like WireShark?
Normally JMeter sends a HTTP request and waits for a response to measure the response time and then to send a next request.
I have a situation where they have created a HTTP endpoint to an embedded software device. But it is one way traffic only, which means I send a HTTP request, but the embedded device doesn't send a response. This is the intention and how it should work.
Is it possible that JMeter doesn't wait for the response and just sends a next request?
A way to do it is to set a Response timeout on the HTTP Request and add an assertion to ignore response timeout.
1 second for response timeout in HTTP Request:
And adding a Response Assertion that ignores status and expects a Timeout:
But this is not very clean.
