I recorded a web page using JMeter which has produced several samplers. Each of those samplers (http request) has a config HTTP Header Manager. Is it really necessary to have that for each sampler or can I just maintain one at the thread group level. Of course some of those Headers have referer header element and some don't.
You don't need one header per request, unless each request need a unique header.
You may not even need ONE at the threadgroup / test plan level, unless you are wanting to specify header information.
When you record, there is a checkbox in the HTTP Proxy to toggle capturing these.
It is enough one Header Manager per Thread. See documantation http://jmeter.apache.org/usermanual/component_reference.html#HTTP_Header_Manager

My team planned to do API Performance Testing using JMeter 5.0 for my client. My client developed the API in Kubernetes. Just wondering, they gave info such as URI, HTTP Method and Content-Type only. We never have experience using URI. Are these info sufficient to do load test in JMeter? And where do I fill in these info? Is it in Config Element: HTTP Header Manager?
Because usually I only do my enablement using sample website which already provide the URL.
Do I need to ask them to provide the specific URL for this? Or URL can be extracted from URI?
Thanks.
Normally you should put:
Protocol, server name or IP and Port Number into HTTP Request Defaults, this way you will have a single configuration element having these details and in case of change you will need to introduce the change at one place only and won't have to revisit each and every HTTP Request sampler
Individual requests are defined using individual HTTP Request samplers where you need to provide URL Path and request body (if any)
Content-Type and other Headers can be provided via HTTP Header Manager, the same Scoping Rules as for HTTP Request Defaults apply, for example if you want to send application/json for all the requests just add HTTP Header Manager on the top of your Test Plan and it will add the header to all HTTP Request samplers which are at the same level as the HTTP Header Manager or lower.
I'm creating a record using post method from one user & verifying record with another user using Get method so for this I need 2 different tokens so what I did that I have used one Header Manager at the thread level & another Header Manager at HTTP-Request level now problem is that when I am running this Get API will get called & in the request header token of both user is getting passed. Can anyone know how to handle this?
If you need separate Header Manager per HTTP request, put each Header Manager under each HTTP request and not on thread level so it only affect the relevant request
HTTP Header Manager obeys JMeter Scoping Rules, so if you place it at the same level as Samplers - it will be applied to all Samplers.
If you add a HTTP Header Manager as a child of the Sampler - it will be applied to that Sampler only.
My HTTP Request has child HTTP Header Manager. The HTTP Header Manager has dynamic values, and other parameters depending on search on GUI application. See picture. The xsrf-token is dynamic, and auditlog varies depending on my search by vEnl. I am using JMeter 4.0. The HTTP Requests are GET, and therefore cannot use the checkbox "Use multipart/form-data for POST" either. How can I correlate/parameterize in this situation?
Use Regular Expression Extractor in the response of whatever request which has the right value for this Header Manager. Name it for example :testDynaVar
Then use ${testDynaVar} in auditlog's value. The parameter value will be passed to this header manager.
You need to extract this xsrf-token from the previous response using a suitable JMeter Post-Processor, save it into a JMeter Variable and substitute recorded hard-coded value with this variable in the HTTP Header Manager, check out How to Load Test CSRF-Protected Web Sites article for example implementation.
HTTP Header Manager can evaluate JMeter Variables in the runtime and substitute the placeholders with the respective values:
with regards to this auditlog header your question doesn't contain enough information to come up with the proper configuration, from the first glance you can parameterize this ctime argument using __time() function
I have a JMeter plan using an HTTP sampler that I am trying to add a header to the request. The header should be really simple custom: type
But when I run the test I don't see the header....
What am I missing? Why is my header not showing up in the request?
Update
I also tried this but got the same result.
Your issue is due to wrong scoping of Header Manager.
Either put it as child of Get Session or child of Test plan if it applies to whole Requests of test plan.
Example:
If it fails, it could be due to your User Credentials Pre-Processor (which runs before GetSession request is sent), but as you don't show code.
Another option is that you're seeing redirect request instead of initial one, check your config so that you see the 2 requests:
I had the same issue (When editing the HTTP Header at the thread level it would use my old values) I didn't realize I had a HTTP Header at a lower level as well. So make sure to remove any other instance of HTTP Header manager. I had one at the Thread Group level and the https request level. I deleted the one at the https level and it fixed my issue.
For my application when I record , each HTTP request has required Headers that are maintained at individual HTTP Header Manager.
Now an Authentication token is also managed in the Header manager for every request after login. For multiple users I pass variable for this Authentication token. To make this happen I need to edit in every Header(or I do it opening jmx file in Notepad++ and then replacing all). But is there any way like using a global HTTP header manager that will override over Sample lever Headers.
As per Using JMeter's HTTP Header Manager article:
JMeter now supports multiple Header Managers.
The header entries are merged to form the list for the sampler. If an entry to be merged matches an existing header name, it replaces the previous entry, unless the entry value is empty in which case any existing entry is removed. This allows one to set up a default set of headers, and apply adjustments to particular samplers.
If you don't like the situation you can uncheck "Capture HTTP Headers" box in the HTTP(S) Test Script Recorder
If all headers are same throughout the script then you can remove all individual headers which are currently child of http request samplers and keep only one header manager outside of all request which will act as a global header manager and it will pass values to all requests
