When i use samplerGRPC Request in Jmeter it gets response 200/300/400/500 and then connection closes and cannot be reused.
I want to reuse this connection for new request or making gRPC calls. Maybe it has the same option as "keepalive"?
Now my TestPlan looks like:
--Thread Group
--GRPC Request
If you're talking about this plugin I don't see any possibility to control how connections are being used/re-used, you might want to implement it yourself by invoking ClientCaller class methods from the JSR223 Sampler

I am using the HTTP request sampler, In which I have used Post Method.
When I Execute the request, it executes the another HTTP request from another thread.
I want to extract the data from that thread because that HTTP request contains the transaction id and I want to use that transaction id in other threads.
The said transaction id is only showing in the pop up message.
Kindly help me.
Solution for the first problem retrieving data from request URL i.e.transaction id using a postprocesser, you can refer the following thread,
Post processer for extracting a value from the URL in the request method.
Solution for the second problem passing the variable from one thread to another,
You need to add a beanshell assertion and set it a property variable like ${__setProperty(transaction_id, ${transID})}
In the second thread group add a preprocesser and accept the property variable.
String tid= props.get("transaction_id");
vars.put("TID",tid);

Thread2:
JMeter can only extract data from response body, message, code, headers, or URL.
If you send the request which triggers another request and the data you're looking for is not in the 1st request response scope - unfortunately you won't be able to get it.
The only option I can think of is using WebDriver Sampler which provider JMeter integration with Selenium browser automation framework so you would be able to execute the request and get the data from the popup using real browser.
WebDriver Sampler can be installed using JMeter Plugins Manager
When using jmeter for interface testing, I want to reuse a certain httpsample. For example, there are 3 http requests, the first http request needs to be sent before the third http request is sent, which is equivalent to initialization, but I don’t want to add an http sampler before the third http request, which will cause http requests Redundant and difficult to maintain. what should I do? Does anyone know?
Put your "fist http request" under the Test Fragment
Reference it where required using the Module Controller
This way you can avoid code duplication and have only one instance of the "first" http request sampler across your test plan
I am trying to simulate a parallel ajax requests using a JSR223 sampler, as mentioned here https://www.blazemeter.com/blog/how-load-test-ajaxxhr-enabled-sites-jmeter
But for my set of requests ,I am getting an error,Invalid API/Auth Key
I assume it is is becuase the authentication cookie is not being passed ,I tried to grab the cookie from the previous sampler using
HTTPSamplerProxy previousSampler = ctx.getPreviousSampler();
CookieManager cookieManager = previousSampler.getCookieManager();
HTTPSampleResult previousResult = (HTTPSampleResult)ctx.getPreviousResult();
log.info("Cookie Count is : "+ cookieManager.getCookieCount());
But I get the error
Cannot invoke method getCookieCount() on null object
,I do have the cookie manager enabled in my test plan.
Any help on what I am doing wrong would be great .
The error you're getting means that there is no HTTP Cookie Manager associated with the sampler. You need to add it to your Test Plan and your code should start working as expected.
Be aware that as of now there is a much easier way to implement AJAX requests without having to do any coding, there is Parallel Controller which can be used to mimic AJAX calls by running its children in parallel. Just add it to your Test Plan and move HTTP Request samplers which represent AJAX calls under it. See How to Use the Parallel Controller in JMeter for more details if needed.
I am using groovy as the language and want to read the server IP value is that was set in the HTTP Request Defaults configuration item.
I looked at http://jmeter.apache.org/usermanual/functions.html and a few other places but nothing useful I can find.
Thanks,
Dan
Actually there is no such thing as HTTP Request Defaults in JMeter script, it is only abstraction layer made for your convenience. When the test is being run the values are merged into HTTP Request samplers where the relevant field(s) is(are) blank. So instead of getting the server IP value from HTTP Request Defaults you should be getting it from the HTTP Request samplers.
I would recommend using JSR223 PostProcessor, add it as a child of the HTTP Request sampler and use the following code:
def serverIP = sampler.getDomain()
It is also possible to do using JSR223 Sampler for the previous sampler (which is supra in the Test Plan) like:
def serverIP = ctx.getPreviousSampler().getDomain()

I want to execute Ajax requests in JMeter. I record my test plan with JMeter and BlazeMeter but none can handle Ajax requests. How can I solve my problem?
Or is there any tool that can send concurrent Ajax requests?
Thanks in advance,
M.A
By default, Ajax requests can't be simulated by JMeter as it does not process .js files (As of 3.1 version). You have to explicitly add the requests (HTTP Samplers) for AJAX requests.
Use Network tab of a browser (F12 option) and filter the traffic by xhr, which shows only AJAX requests. Add those requests as HTTP Samplers in the script at the point you needed in the Test Plan.
Browser can process .js files, hence AJAX requests are sent from the browser. When you record the script using HTTP Test Script Recorder, as you are using the browser to navigate, even AJAX requests (originated from js files) will also be added/recorded to the Test Plan.
Since JMeter can't process .js files due to limitation, manually add the AJAX requests (nothing but HTTP Get or Post requests) using HTTP Sampler, if you are building the Test Plan without HTTP Test Script Recorder.
Note: If you are using HTTP Test Script Recorder, no need to add them manually as they are already recorded in the Test Plan.
you can do that by recording http traffic with JMeter Proxy
http://jmeter.apache.org/usermanual/jmeter_proxy_step_by_step.pdf
but it is only possible to replay the same traffic, can be problematic for sessions, cookies...
Better solution is to use WebDriver
https://jmeter-plugins.org/wiki/WebDriverTutorial/
https://jmeter-plugins.org/wiki/PluginInstall/
the needed package is https://jmeter-plugins.org/files/packages/jpgc-webdriver-1.4.0.zip
It is not possible as kicking off more threads than originally defined in the Thread Group is not currently supported, the feature is being tracked as Bug 53159. AJAX requests are "normal" HTTP Requests so JMeter can record and replay them, but when it comes to asynchronous execution - you cannot do this as of now. The workaround options are in:
Use WebDriver Sampler plugin so each JMeter virtual user will kick off a real browser. Warning: this way is very resource intensive.
Use scripting, i.e. JSR223 PostProcessor to kick off AJAX-driven requests via Apache HttpComponents
Develop your custom sampler. You can use the current way of handling embedded resources as a reference.

I had this same problem after recording samplers using the JMeter Proxy. The answer was on this blog post: https://lincolnloop.com/blog/load-testing-jmeter-part-1-getting-started/ - see the Ajax Requests section.
Add an HTTP Header Manager for the ajax request and make sure you are sending the X-Requested-With:XMLHttpRequest header.
