What is acceptable definition of performance testing today: • Start by begging customers for performance requirements. • Conduct testing in an environment which doesn’t match production • Extrapolate results to estimate production response times • After go-live, do emergency performance testing on production • Deploy remote load generators to capture end-user experience • Try to explain “what happened” after it’s too late. Let’s take a deeper look…www.shunra.com

What risks do we have today without Real-world Testing: • Our test results can be grossly inaccurate – or just plain wrong • Over-confidence based on false positive test results • Starts the ‘cry-wolf’ experience – nobody believes you • Time wasted trying to fix issues that would never happen • Outages cause end-users lose faith in IT or Technology • Financial costs due to emergency spend to fix the issuewww.shunra.com

Please submit your answer inthe Polling Panel on the right of your WebEx screen.What does one hour of applicationperformance issues cost a business?

“Productivity loss due to application performance issues is estimated at a loss of $42,000 per hour for each user group impacted.” (IT Management News)

• What: Enables Load Generators to simulate network locations Shunra and HP Software co-developed the solution Integrated with HP LoadRunner and HP Performance Center Includes: Shunra vCAT, Shunra NetworkCatcher Shunra Profiler and Analyzer • Why: Eliminate the risks of deploying Load Generators remotely Capture the real-world conditions and bring them into the lab Correlate complicated analysis results Merge results together to see real-world performance Aggregate end-to-end results into a single database Shunra for HP Software is the only WAN emulation product that can provide this functionality.www.shunra.com

Upgrade your load testing efforts by importing real-world network conditions into the Network Editor using Shunra’s NetworkCatcher. Latency (Jitter) and Packet Loss of your network are measured over time and then emulated in your load test.www.shunra.com

• Shunra’s technology is built-in to the HP Controller (or PC Host) • WAN emulation is defined on a per Load Generator basis • Load Generator configurations are saved in the Scenario • No limits on test scheduling (e.g. by scenario, group, etc.)www.shunra.com

• Access in the Load Generator Details • Name each emulated location • Configure settings: • Basic (easy) pre-configured • Advanced specification • Professional integration with NetworkCatcher profileswww.shunra.com

Easy Adoption: No script changes required to run with WAN emulation Real-time metrics: Automatically added for every Load Generator running WAN emulationWAN Emulator indicatorwww.shunra.com

Sorting by Emulated Locationwww.shunra.com

Sorted results tell how end user experiences vary by location.www.shunra.com

Correlate ResultsBy having all statistics in one location, end-to-end correlations can be easily done. Imagine being able toinstantly tell if an issueis caused by the server, the client, or the network…www.shunra.com

Merged Results Merging your application results with your network results gives you unique insight to the true network impact on your application performance.www.shunra.com

Extend LoadRunner Enable Transport Level LoadRunner + Shunra for LoadRunnerautomatic + Analysis for Analysis analysis by reporting analysis ofAnalytics HP Software Shunra application location specific SLAs behaviors Experiment with SLAs by LoadRunner/VUGen + Replace remote Load Generators with manually running scripts with LoadRunner + Shunra for HP Software Shunra vCat emulated locations network emulation Enhance existing test Network Emulation for LoadRunner + Shunra LoadRunner + Shunra scripts and scenarios to PerformanceSuite WAAS testing for HP Software be network aware Bring real-world production Shunra NetworkCatcher + conditions into the Load LoadRunner + Generator configurations Shunra for HP Softwarewww.shunra.com

If you have HP LoadRunner: • Planning: ask about location and connections, mobile and geography • Preparing: capture end-user locations with Network Catcher • Scripting: enhance Vuser scripts with Shunra transaction measures • Run-time Settings: configure think-time and iteration pacing • Scenario Config: configure emulation on separate load generators • Analysis: correlate response time to the new “Emulated Location” • Results: leverage the automatic analysis from Shunra Predictorwww.shunra.com

If you have HP Performance Center: • Policy: make real-world emulation a requirement for all testing • Planning: add a section to your questionnaire – detail the end-users • Preparing: create and maintain a library of network profiles • Scripting: create re-usable function library for Shunra API calls • Run-time Settings: configure think-time and iteration pacing • LG Pools: setup a separate pool of Load Generators used with Shunra • Scenario Config: configure emulation for that pool of load generators • Analysis: correlate response time to the new “Emulated Location” • Results: leverage the automatic analysis from Shunra Predictorwww.shunra.com
