JMeter Complete Element Reference – Part IV

In this article, we will discuss about  the next set of elements i.e Logic Controllers, importance  of controllers, types of controllers and their usage  in our test. In case if you have missed the older parts, click here 12, 3.

Logic Controllers

Logic Controllers let you customize the logic that JMeter uses to decide when to send user requests. Logic Controllers basically determine the order in which Samplers are processed. They can modify the requests themselves, cause JMeter to repeat requests, etc.

Recording HTTPS Traffic with JMeter’s Proxy Server

If you read our article, Recording using Jmeter HTTP Proxy Server, then you already know how to use JMeter’s Proxy Server to record HTTP traffic.
But what if a website uses SSL encryption? 
Then, you better make some configuration changes. How? We’ll tell ya’.

Record HTTPS Traffic with the JMeter Proxy Server

By default, JMeter supports recording HTTPS (SSL) in versions 2.3.4+ and HTTP Samplers are configured to accept all certificates, whether trusted or not.
To record encrypted traffic, first configure the JMeter Proxy Server and browser proxy settings. We used Firefox for this example.

HTTP Request Sampler

In the last article, we discussed about Samplers, sampler usage and many more . In case if you have missed click here. In this article, We will discuss about the most important and frequently used sampler i.e “HTTP Request Sampler”.

HTTP Request Sampler

This sampler lets you send an HTTP/HTTPS request to a web server. It also lets you control whether or not JMeter parses HTML files for images and other embedded resources and sends HTTP requests to retrieve them. The following types of embedded resource are retrieved:

  • images
  • applets
  • stylesheets
  • external scripts
  • frames, iframes
  • background images (body, table, TD, TR)
  • background sound

The default parser is htmlparser. This can be changed by using the property “htmlparser.classname” – see for details.

If you are going to send multiple requests to the same web server, consider using an HTTP Request Defaults Configuration Element so you do not have to enter the same information for each HTTP Request.

Or, instead of manually adding HTTP Requests, you may want to use JMeter’s HTTP(S) Test Script Recorder to create them. This can save you time if you have a lot of HTTP requests or requests with many parameters.

Performance Testing – Workload Model

In this modern era, we are living in a space where almost everything is found over World Wide Web. Only perquisite you need is to have proper internet connection at home and it feels like you have the whole world in your hands 😛 .If you search for any information over the web, you end up with countless providers who are just few clicks away from you. This growing competition also demands better customer services to get the competitive edge. Main purpose of web applications is to facilitate the users in getting their desired information in a quick and efficient manner.

Thus a web applications performance is the most important parameter to attract and retain maximum users. So now we know that “performance” is the key to any web application, how do we measure an applications performance? how to plan a proper and efficient approach? The answer is “performance testing” with a well planned “Workload Model  is designed  to validate whether they are meeting users expectations or not and also to reduce the identified performance bottlenecks.

What is Workload Model?

Distribution of load across all the identified scenarios of AUT(Application Under Test) is called the Workload. A workload model is designed to identify key test scenarios and load distribution across these scenarios. Performance test results can never be reliable unless its workload model is designed accurately. Identification of key test scenarios and load distribution across these scenarios is one of the major parts of a performance test plan which lies under the workload modeling. In performance workload modeling phase, a complete understanding of AUT is developed for multiple purposes such as to identify its test objectives, to figure out all its users’ types and their activities, to identify application key business scenarios along with their navigation paths and eventually to analyze and evaluate the load distribution across all identified scenarios and their navigation paths.

JMeter Complete Element Reference – Part II

In this article, we will discuss about  the next set of elements i.e Samplers, importance  of samplers, types of samplers  and their uasge  in our test. If you have missed the first part, click here


Samplers perform the actual work of JMeter. Each sampler (except Test Action) generates one or more sample results. The sample results have various attributes (success/fail, elapsed time, data size etc) and can be viewed in the various listeners(will get to know in future posts 😛 ).

As we all know that Apache JMeter has ability to load and performance test many different server/protocol types such as HTTP, FTP, SOAP, LDAP, JDBC etc and we aslo know that Thread Group forms the base for simulating requests to the server.  Now we have problem here, how does a thread group knows which user request to make ? more over user request can be FTP request or HTTP request or SOAP request. The answer is quite simple Samplers, using samplers we can define what kind of request has to be simulated using JMeter.  Apache JMeter supports various types of samplers, lets go through each sampler in detail :

JMeter Complete Element Reference – Part I

In the previous article, we have learned about recording a test script using JMeter HTTP proxy server. So, lets dive deep into numerous elements which can be used for building exceptional test scripts using multiple protocols and many more.

JMeter Element Reference

Apache JMeter has wide variety of elements which are defined for a specific purpose. Since JMeter is pure java desktop application and provides a feasible way  of additional custom packages or plugins available on the net  which are used for multiple purposes such as resource monitoring, running selenium scripts and many more. Below are the configuration elements which Apache JMeter supports.


In this article, we will discuss about “Threads(Users)”.  Studying all the elements at one go is an invitation to confusion and boredom.
