I use JMeter to load data using web services. I need to login from JMeter once, then I need to read ids from CSV file and call HTTP request for each id.
My current configuration is as in the attached picture.
The problem is that in this case login is called for each HTTP Request. I want to change it, so it will be called only once at the beginning. What is the best way to do it in JMeter?
Right click on login -> Insert Parent -> Logic Controller -> Once Only Controller:
The Once Only Logic Controller tells JMeter to process the controller(s) inside it only once per Thread, and pass over any requests under it during further iterations through the test plan.
..
For testing that requires a login, consider placing the login request in this controller since each thread only needs to login once to establish a session.

I created a script multiple user logins and redirected to the home page. For multiple user logins fetching data from CSV file but after logged in, home page redirection is not working.
There are multiple possible explanations:
Your login fails somewhere somehow so you're still at the login page, check the server response using View Results Tree listener and if this is the case - fix your script. It might be sufficient to add a HTTP Cookie Manager to represent user session
You might need to play with Redirect automatically / Follow redirects checkboxes on HTTP Request sampler level
Your redirect is being managed by JavaScript and JMeter is not capable of executing JavaScript so you need to extract the desired redirect location using a suitable JMeter Post-Processor (basically implement correlation of the redirect URL) and add another HTTP Request sampler to open the redirect target.
More information: Redirections in HTTP
In general make sure that JMeter sends the same requests as the real browser does, given this simple rule is met you should be able to properly simulate real user actions
I'm using jmeter to load test a Feature Page.
My jmeter requests (for that page) are being redirected to a login page. How do I provide login info for that redirect?
I already tried:
Controller
Login Page
Feature Page
Logout
But somehow a user even though already authenticated via Login Page is still being asked to login on the Feature Page.
Wondering if someone has a suggestion.
Make sure you're really logged in as "green" result in JMeter doesn't necessarily indicates successful request. You can verify responses using View Results Tree
listener
Add HTTP Cookie Manager to your Test Plan, if your application uses cookies for establishing/maintaining user session it should automatically resolve your problem
Inspect your test plan for any dynamic values (request parameters, headers, URL postfixes, etc.), if the are - they need to be correlated.
How to maintain session in Jmeter so that each user should login, search tickets and then logout ? and this process kept going until loop completes for all users.
As I am trying to test our web application with multiple users.
Each JMeter Thread (representing a virtual user) executes samplers upside down so if you have 3 samplers for login, search and logout each thread will execute them in that order.
Keep in mind that:
You need to provide different credentials to each thread so they could impersonate different users. The most common way of parametrization is using CSV Data Set Config
It's better to add HTTP Cookie Manager to represent browser cookies.
It may also be required to perform correlation: in majority of cases application expects dynamic parameters which need to be extracted from previous page response and added to the next request. If you fail to do it you may not even be logged in. The most commonly used test element for correlation is Regular Expression Extractor however depending on the nature of the response it may worth be using CSS/JQuery Extractor, XPath Extractor or JSON Path Extractor
Add Cookie manager. Afterwards it depends on the application you will need dynamic values like viewState or eventValidation or similar ones. But first add the manager and get to the next problem :)
How to Configure Jmeter for after Login process in an Application?
I am able to configure the login request for 100 users from the CSV file with the help of Jmeter's "CSV Data set Config", but after the successful login of all I want to know how to configure the jmeter to go to the "Offers" page of there(100 user) accounts.Means 1 User can login & View his/her "Offer" page.Please Help.
There are two ways to achieve this scenario:
add another HTTP sampler & fill the details like Server IP, Path of Offers URL (you will have already done the same for Login), HTTP Header data etc. and pass correlation parameters from the response of Login if required to view the offers specific to 1 user.
make sure you use right method (GET/POST) in HTTP Sampler.
record the whole scenario (ref: http://jmeter.apache.org/usermanual/jmeter_proxy_step_by_step.pdf).
You will still have to do the correlation of parameters (using regular expression extractor or Xpath extractor) wherever required. This entirely depends on the parameters required for the offer page HTTP request.
hope this will help.
You'll need a cookie manager to store the session and cookie for all logged in users.

I am testing some api for our product using jmeter. To test the api to verify the user's email address I need to login to the mail account. I have the email and password of a test user. How can I login using an api or any other way in jmeter?
Is it possible at all?
Yes that is possible. You'll have to create a test plan with multiple steps but these depend on the concrete implementation of the login.
First you must identify the following two locations:
The GET request that gets the initial login form (if this is required).
The POST request that posts the login credentials.
If your service has a stateless login form you can even skip the first step.
Otherwise the response of the GET request will contain stuff which needs to be extracted (e.g. the JSESSIONID if you are using JSF) and sent as a parameters in the POST request. You can use the Regular Expression Extractor of JMeter to extract these values and provide them as variables for use in the subsequent requests.
Here is an example screenshot of a HTTP Request element configured to POST login data to the url /common/j_security_check
You might also need to intercept an authentication token from the server response and then pass that into following requests.
Here is a blog entry with a couple of video tutorials on logins with JMeter:
http://community.blazemeter.com/knowledgebase/articles/80479-how-to-use-jmeter-for-login-authentication
You can use jmeter to login,
two ways:
parameterization using csv file(for more users)/user defined variables(UDV)
Login config elements(for single user)
Now that I understand you want to automatically click on a confirmation link from an email using JMeter, here is a blog entry that explains exactly how to do that:
