Performance Center

Using minimal hardware resources, HP Performance Center lowers the cost of distributed load testing by providing a standard solution that can be managed via the web.

This integrated performance validation solution emulates hundreds or thousands of concurrent users to apply simulated production workloads to virtually any client platform or environment. Using Performance Center, testing teams can stress an application from end to end—applying consistent, measurable and repeatable loads—and then use the data to identify scalability issues that could impact users. HP Performance Center:

• Lowers the cost of distributed load testing

• Reduces the risk of deploying systems that do not meet your performance requirements

Creating Load Test

1. Launch Performance Center link.
2. Under Load Test tab click on Manage and then to create new load test click on New Load Test
3. To manage load test, there are four tabs General, Workload, Monitors, Diagnotics.
4. In General tab, we specify load test name and description like type of test (baseline, benchmark), number of Vusers
5. In Workload tab, there are four types of scenario, most of the time we choose Basic Schedule, by load test and Vuser distribution option as by number.
6. Like LoadRunner Controller, there are many tabs to manage scenario.
7. In the Scripts tab, you can Add Scripts, Vusers, Load Generators.
8. In Global Schedule tab, you mention the properties like Initialize, Start Vusers (Ramp Up), Duration of the test run and Stop Vusers (Ramp Down).
9. To apply same runtime setting to all groups, Click on Duplicate Runtime Settings and select source group and target group to apply runtime settings.
10. For managing load generators, click on LG Distribution, choose Manual Distribution, under that choose Assign Actual LG to groups.
11. Select load generators.
12. To add and edit monitors, click on Monitors tab
13. To add monitors click on Add Profile, create New Profile.
14. Specify Profile name and description like App Server, Web Services, Database Server
15. Choose monitor like Windows Resources, under System Resources graph.
16. Choose Server which you want to monitor, provide server name, username, password for that server.
17. Select the Measurements like Page Faults/Sec, Processor Time.
18. In Diagnostic tab, enable the diagnostic.
19. Specify value for Perform diagnostic breakdown on X %.
20. Enable Web Page diagnostic of all relevant Vusers.
