Difference between Load Runner and Load Generator

Hi all,

I am new to load runner and would like to install it on a Ubuntu 16.04 server version. However I am not sure it allows installation on this OS. Reading through the installation manual, chapter 2 talks about installing load runner on windows while chapter 3 talks about installing load generator on Linux.

Please can you explain to me the difference and how I am supposed to go about it. I will appreciate your response.

Thank you.

Re: Difference between Load Runner and Load Generator

Hi Kums,

LoadRunner is the entire tool / solution and contains all components. As such - it can be installed only on a windows OS.

If you install in a distributed mode (i.e. all parts installed separately on dedicated servers) - you can install the Load Generator, the module that injects the actual load on the AUT, on a Linux OS.

As you are a newcomer to the tool, I recommend you start with reading the documentation, go through the tutorial and I believe you'll have a better understanding of the different components.

Hope this helps,

Lior

Re: Difference between Load Runner and Load Generator

Thank you so much for the reply. I will look through the tutorial. I already used the tutorial by guru99, but will have a look at the one you sent me.

Can you please enlighten me on this. I have an application deployed on a Ubuntu server and would like to use Load Runner for testing and since I can't install load runner on Ubuntu, what is the best approach to use. I want to keep the issue of internet connectivity out of it, although I read that one can configure Load Runner to simulate the bandwidth needed.

Thank you and looking forward to your response.

Re: Difference between Load Runner and Load Generator

Hi

As a rule - do not install LoadRunner (or the Load Generator) on the same server as your AUT is installed on. This will lead to wrong measurements and will create a bad run.

If you're AUT is in a data center, you can install LoadRunner on a different server and load that AUT from the same data center.

Network connectivity is always a factor to consider when running load test and should not be ignored if you need to test user experience of your application as well.

Thanks,

Lior
