After running a simulation, VE Reporter provides application-performance details. Generic TCP analysis includes packet statistics, a bounce diagram and other salient details, which let us determine whether a test run was acceptable or skewed. VE Reporter ships with an HTTP analysis module that reports on overall application performance and summarizes HTTP events.

Good Definitions

Shunra's analysis gets interesting when you define transactions. You use the Transaction Manager tool, which records application activity, to define the initiating and terminating events of transactions. We tested a Web application and found you could define getting a page, entering and posting the data, and getting a response from the Web server as a transaction. Then the VE Analyzer can report on the number of transactions that pass or fail based on a set of criteria you define.

When the test is run through the Shunra VE, the transactions are listed as app statistics showing average transaction times, number of transactions and the number of passed and failed transactions. By varying WAN conditions in the diagram--using your own recorded network samples or one of Shunra's library of network samples--you can view the impact on your applications. This gives you the crucial ability to optimize performance based on WAN conditions.
