This blogspace is meant to be a one-stop shop for anybody wanting to learn about HP Load runner.
LoadRunner is HP’s tool for application performance testing.LoadRunner stresses your entire application to isolate and identify potentialclient, network, and server bottlenecks. LoadRunner enables you to test yoursystem under controlled and peak load conditions.
When i started load runner i dont know from where to start. So i thought of posting my experiences to beginners. My intention here is to collate the useful information on Loadrunner scattered all over the web.
Performance Testing
Performance Tests are tests that determine end to end timing (benchmarking) of various time critical business processes and transactions, while the system is under low load, but with a production sized database. This sets ‘best possible’ performance expectation under a given configuration of infrastructure. It also highlights very early in the testing process if changes need to be made before load testing should be undertaken. For example, a customer search may take 15 seconds in a full sized database if indexes had not been applied correctly, or if an SQL 'hint' was incorporated in a statement that had been optimized with a much smaller database. Such performance testing would highlight such a slow customer search transaction, which could be remediated prior to a full end to end load test.
We can add transaction Points while we record
or we can add add transaction points after recording by
go to menu options-> Insert-> Start transaction-> enter the transaction name and click on button

Wat is the use of transaction points?
Hi sirisha
How can we monitor CPU usage in Loadrunner?
hi mahesh.. Transaction Points are used to check the performance(response time) of certain action. Suppose u need to check how much time it takes to login to an application. u need to add transaction point before logging in and end transaction after logging in while u record ur script. this time how much time a application takes to login the user after he clicks on Login button. Let me know if u need more information
hi kranthi .. After executing ur script in controller u can see that the results are generated. But by default u can find CPU usage . So u need to go controller where u have executed the script. Select Run tab. U can see Avaliable graphs on left hand side. Go to Web resource graphs. Select apache and right click and select open. Now u can see Apache-last 60 sec graph on right hand with no data in it.
Now to view the CPU usage U need to right on click on Apache graph on right hand side and select Add measurements
A dialog box apache is invoked
Click on Add button and enter your machine information
Now u can view the CPU usage. let me know if u have any doubts
Hi Sirisha..
Could you please explain about sub transaction points and How to insert sub transaction points in LR?
