I am fairly new to jmeter and currently I am using jmeter to create a test plan with Prometheus plugin, we have various endpoints that needs to be probed, our application use a cookie that refreshes every day so the cookie value changes likewise. Once the jmeter runs on the host, it gives 200 response code but after a day, when the cookie refreshes, we start seeing 401s for all the endpoints, my guess is the cookie is not being generated properly. I am using HTTP cookie manager in the jmeter which supposedly gets the cookie automatically, and I also have selected clear cookie each iteration but it doesn’t seem to work.Please help.
HTTP Cookie Manager does really clear cookies but it applies only to Thread Group iteration, other Logic Controllers like Loop Controller or While Controller won't trigger cookies renewal.
You can check what exactly is happening by enabling debug logging for the HTTP Cookie Manager: add the next line to log4j2.xml file:
<Logger name="org.apache.jmeter.protocol.http.control" level="debug" />
and upon JMeter restart the jmeter.log file will contain information regarding incoming and outgoing cookies.
It's also possible to force clear cookies, it can be done by adding a JSR223 PreProcessor as a child of the very first HTTP Request sampler and putting the following code into "Script" area:
sampler.getCookieManager().clear()

I have placed cookie manager above the thread group.I have extracted cookie value from sampler request(request1) using regex extractor.I have placed cookie manager with extracted cookie values under the sampler(request2).
When i replayed the script the cookie is not set for request2.It shows no cookies.
NOTE:
When I removed the cookie manager placed above the thread group I am getting errors in samplers.

HTTP Cookie Manager handles incoming cookies automatically, it:
Extracts the cookies from the Set-Cookie response header
On subsequent requests if domain and path of the request matches the ones of the cookie(s) the cookie is being added to the request's Cookie header
So there is no need to use any post processors for extracting the cookies.
If the cookie manager is "not working" most probably there is a problem with the cookie, i.e. it's expired or domain of the request is different or something like this. If you want to see what's going on under the hood you can increase JMeter logging verbosity for the cookie manager by adding the next line to log4j2.xml file:
<Logger name="org.apache.jmeter.protocol.http.control" level="debug" />
if there are issues with cookies and JMeter is unwilling to add the cookie you can force it by
Choosing less restrictive policy, i.e. netscape
Adding the next line to user.properties file:
CookieManager.check.cookies=false

I am using apache jmeter 5.2.1 with Java 8 to perform the performance test in a JSF application.
I need to send in the header of an HTTP request a parameter called "Cookie" according to the example below:
I've tried several things but none work.
I have already used the HttpHeaderManager resource but apparently the word "Cookie" is a JMeter reserved word so I can't create a parameter in the Header with the name "Cookie".
If I create a parameter in HttpHeaderManager with any name it is appended to the request header, but if I create with the name "Cookie" which is the name I need to use JMeter simply ignore it and do not add it to the request header .
I saw many posts indicating that I used the following code snippet:
CookieManager manager = sampler.getCookieManager();
Cookie cookie = new Cookie("JSESSIONID",vars.get("jSessionId"),"${serveraddress}",false,0);
manager.add(cookie);
I've tested it but it doesn't work either, it returns the following error whenever I try to use it:
I also have an Http Cookie Manager but its value is sent in the request body and not in the header.
I also tried to use the Http Autorization Manager as I saw in some posts but it only works when the login is done at a prompt in the browser.
Can someone help me?
Just add a HTTP Cookie Manager to your Test Plan and it will automatically "manage" cookies for you (the HTTP Request samplers must be in the HTTP Cookie Manager's scope)
You can double check that JMeter sends correct Cookie header using a 3rd-party sniffer tool like Wireshark or Fiddler
If you added the HTTP Cookie Manager but JMeter still doesn't send the JSESSIONID cookie it might be the case there is a problem with the cookie itself, i.e. it doesn't match domain/path or expired or your HTTP Request sampler configuration is not correct.
If you absolutely sure that your application behaves as expected you can configure JMeter to be less restrictive by:
Choosing a more "relaxed" cookie policy, i.e. netscape
Adding the next line to user.properties file:
CookieManager.check.cookies=false
You can also add the next line to log4j2.xml file:
<Logger name="org.apache.jmeter.protocol.http.control" level="debug" />
this way you will get comprehensive information of the Cookie Manager's behaviour in the jmeter.log file

I used Jmeter's HTTP(S) Test Script Recorder to record the Log in in SAP CRM Web client. I configured HTTP Cookie Manager using the cookies that I saw in browser developer tools ( MYSAPSSO2, Session ID, Sap-usercontext).
In the same recording test I filled some fields in SAP. I stopped the recording test.
I did it multiple times to see what parameters were dynamic and I realized that wfc-secure-id and C5_confighash and c7_confighash were dynamic. So I used regular expression to extract the dynamic values and I applied it in the requests where I filled the fields.
In View Results Tree I can see the HTML response in the Requests' response bodies that the log in was successful and the fields were filled. I also checked the SAP sessions metrics that the users are logging in.
After the successful login I went and did some recordings of a User roaming around inside the web client performing some operations and saving the results. I changed the dynamic values to fit the previously values I obtained in the login process.
The issue lies in the fact than when i went back to JMeter to do a test run, I get a logon error on the response header between the login and the new recordings. The response body of the new recordings also return empty.
I'm thinking that between the recordings, jmeter is losing the user session information
How can I connect the new records with the log in record?
You should not be hard-coding cookies in the HTTP Cookie Manager.
JMeter doesn't record cookies
headers.removeHeaderNamed(HTTPConstants.HEADER_COOKIE);// Always remove cookies
hence you should not be manually adding the cookies you see in browser to the HTTP Cookie Manager, adding an empty HTTP Cookie Manager should be enough to let JMeter automatically take care of incoming cookies.
If you don't see the cookies being added to the request(s) it usually means that:
Your HTTP Request sampler is not configured properly, i.e. "Server Name or IP" field is empty
Your server is not configured properly (i.e. it returns cookies which doesn't comply with the standard hence JMeter fails to add them)
The steps you could take are:
Enable debug logging for the HTTP Cookie Manager by adding the next line to log4j2.xml file:
<Logger name="org.apache.jmeter.protocol.http.control" level="debug" />
Use less-restrictive cookie policy, i.e. netscape
Add the next line to user.properties file:
CookieManager.check.cookies=false

I have added HTTP Cookie Manager and HTTP Authorization Manager in Test Plan. When run the script following response message I have received
Response code: 401
Response message: UNAUTHORIZED
{"message":"Access is Denied","severity":"danger"}
This is my cookie
_ga=###; _gid=###; _gat=#; accessInfo={###}; userInfo={###}; 574ae166fc51fa5bdbd8beef725e77d7={###}; session=.###
But when run script only partial session is pass from my above cookie data through header request.
I also tried using regular expression but not getting response.
Can anyone suggest me how and where I can pass my cookies dynamically?
If the next request doesn't have all the cookies which you can see in the previous response Set-Cookie header most probably it indicates problem with the cookies.
You can check what exactly JMeter does with cookies by enabling debug logging for the HTTP Cookie Manager, in order to do this add the next line to log4j2.xml file (lives in "bin" folder of your JMeter installation:
<Logger name="org.apache.jmeter.protocol.http.control.CookieManager" level="debug" />
JMeter restart will be required to pick up the change.
Other things to try:
Turn off JMeter built-in checks for cookies. In order to do this add the next line to user.properties file
CookieManager.check.cookies=false
Play with "Implementation" drop-down value, i.e. try choosing less restrictive implementation, for example netscape
I am doing load test for my application. For login i am getting set-cookie in response headers. Is it possible to append all cookies using cookie manager and sending it in request header for another request
Just add cookie manager to you thread group.
Jmeter will automatically transfer the cookies to the further request correspondingly
Add HTTP Cookie Manager to your Thread Group, it should handle cookies automatically.
If it doesn't pick up all the cookies, there should be an issue with one or more cookies, i.e. Domain or Path mismatch or expiration date is in the past or whatever. If this is the case and you still want JMeter to consider the invalid cookies you can try adding the next line to user.properties file (located in JMeter's "bin" folder)
CookieManager.check.cookies=false
Given this property set to false JMeter won't check cookies before storing them and you should see "missing" ones, however I would recommend raising a defect against your application as the fact you are not seeing the cookies added by the HTTP Cookie Manager indicates that something is wrong with them
