In Jmeter test plan, I have too many http requests. One of this creates a new session every time when clicking the create button. After that other http request use that session id in URL.
How to get that session id when we call create button and put it into other request URL?
Sounds like a use-case for the HTTP URL Re-writing Modifier, just provide your session id as the "Session Argument Name" and it should do the "magic" of hard-coded parameters substitution for you.
See Using the HTTP URL Re-writing Modifier article for comprehensive explanation and real-life usage scenario if needed.

We are using the jmeter recording template to see the api requests by our unsigned app.
When we use charles as the proxy, we are getting all the urls properly.
But when we use the jmeter recording template, we get 'MISSING PARAMETERS' for all GET requests. Essentially, jmeter does not get any parameters that are sent with the GET request.
POST requests work properly.
Any advice?
For convenience JMeter stores the request parameters under "Parameters" section of the HTTP Request sampler
it's better to work with attribute-value pairs for parameterization or correlation purposes than having to edit the URL string which might be very long.
If you replay your recorded request(s) and look into Request tab of the View Results Tree listener you will see that the parameters are concatenated to protocol, domain, etc. in the URL:
I am testing an API endpoint for which there is a form based authentication(for additional security). Can someone suggest how to handle form based authentication in Jmeter. I tried with HTTP Authorization Manage, still my request is failing.
You basically need to submit a HTML Form by sending a HTTP POST request using JMeter's HTTP Request sampler.
Given you provide correct credentials you should be authorized for further actions.
In some cases you will need to perform correlation as you might have to provide a dynamic parameter (or several) along with the credentials as your application can use these parameters for i.e. CSRF protection or for other reasons so make sure to carefully inspect the request sent by the real browser (you can capture the original request using browser developer tools) and if there are any dynamic parameters - you should extract them from the previous response using a suitable JMeter Post-Processor
Once you successfully log in it should be enough to add HTTP Cookie Manager to maintain the user session.
For my JMeter test, I would like all threads in the test to use one shared session id. The session id is known before I start the test job. How do I specify a specific JSessionId for my JMeter test?
I've tried appending a JSessionId parameter in the HTTP Cookie Manager (under user-defined cookies), in the HTTP Request Defaults (under send parameters with the request), and I tried adding a 'HTTP URL Re-writing Modifier' from the Pre-Processor tab under the Recording Controller. None of these have worked. Which step is the best way to set a fixed session id for my JMeter test?
You were correct when you tried to use the HTTP Cookie Manager, this should do what you need.
Probably, it didn't work for one of two reasons:
You either have the Cookie Manager in the wrong place. To affect all requests it should be at the root of the Test Plan or Thread Group.
Or, more likely, you didn't specify all the required values properly when you added the User Defined Cookie. This can be tricky to get working; have you made sure you're not using 'http://' in the domain field?
You need to add jp#gc-JSON Path Extractor in HTTP request, the particular HTTP request which is generating session id in its response data .
If response is like:
{"sessionId":"f5b06970-f00f-4b44-89c8-305738e19cba","loginDate":1483599209337}
In JSON path extractor add:
Variable name - session (variable in which session id will be stored)
JSON Expression - $.sessionId (this will vary according to the JSON response)
Default Value - NOT_FOUND
Now the next step is to use this variable named "session". You can use it in your HTTP request for which you need to pass session id under HTTP header manager as x-auth-token = ${session}
I am testing particular application using JMeter 2.9.There My test plan is Thread group--> Transaction Controller.Inside that various recorded requests are there.I am using HTTP request defaults,HTTP Cookie manager and HTTP header manager,and a view result tree for validation.I found one token i.e. CSRF token to be correlated and I did correlation.But for a particular request I am finding "Session expired..Login again" response much before the logout request.My transaction flow is to Login--> Search a content-->Logout.
Please help me finding a solution.
Try put the element: HTTP Cookie Manager in Thread Group, first item.
the problem can be in the following areas:
-you were redirected automatically instead of following redirects
-login hasn't succeeded
-the session id has not been successfully passed on to the request after login
The JMeter documentation states this:
I've set up JMeter to sample the same URLs as my browser, why is JMeter not seeing the same responses?
There are various different reasons for this:
Cookies - make sure you added a Cookie Manager. Browsers process cookies unless you set them up otherwise, but JMeter does not process cookies unless you add a Cookie Manager.
User-Agent - the User-Agent is a header that is sent by browsers; it identifies the browser type. Some servers are sensitive to this setting and generate different results for what they think are different browsers. The Header Manager is used to add headers such as User-Agent.
Hidden fields - if you did not use the JMeter Proxy (or other application) to record the test plan, then it is easy to miss hidden fields from forms.
Dynamic field names/content - some servers use varying names for fields. So although the test plan may be correct at the time of creation, it does not work when replayed.
URL rewriting - TBA

I'm trying to do a simple load-test in a website which requires you to log in first.
I read the jmeter documentation about the cookie manager and looks like as long as I make all my requests within the same thread group where the cookie manager is the sessionID is shared among the http requests but is not my case.
The simple structure I have is:
Thread Group
HTTP Cookie Manager
HTTP Requests Defaults
Simple Controller
http request // POST method to authenticate in the site (this works fine, I get a session id)
http request // GET method (this one should use the same session id from the previous http requests but I get a new one instead)
I did this same web page flow in firefox using firebug to see the requests/responses and the session id is the same, the server doesn't send a new one so looks like the cookie manager is not keeping the same session id and using it for all the requests.
Can someone point me in the right direction? What I am doing wrong?
Check the get request sends the same jsessionid cookie in the request as the one returned in previous response.
If it's the case then check your login was fine, as it is probably root cause of issue
