【正文】 users ? Number if hits/second (Web Vusers only) ? Number of transactions/second (script should include transactions) ? Number of pages per minute (Web Vusers only) ? Transaction response time desired for the scenario (script should include transactions) 37 Mercury Tools LR – Controller Configuring a scenario ? The load generators and Vusers set for a scenario can be configured so that the scenario accurately emulates the working environment. ? Some of the important parameters that maybe configured for each scenario: ? Runtime settings ? Timeout interval ? Runtime file storage 38 Mercury Tools LR – Controller Rendezvous points ? Rendezvous points enable you to check your system’s response under specific load. ? Setting a rendezvous point causes multiple users to perform tasks at exactly the same time, thereby creating intense user load on the server. ? The Controller releases the Vusers from the rendezvous either when the require number of Vusers arrives, or when a specified amount of time has passed. ? Rendezvous points are defined in the Vuser scripts. 39 Mercury Tools LoadRunner Monitors ? LoadRunner provides online monitors to measure or gauge the status of various ponents under test, such as: ? Run – time: number and status of Vusers participating in the scenario. ? Transaction: the transaction rate and response time during scenario execution. ? Web Resource: measures statistics at the Web server(s) during scenario runs. ? System Resource: gauges the Windows, UNIX etc. resources used during a scenario. 40 Mercury Tools LoadRunner Analysis ? LoadRunner Analysis provides graphs and reports to help you analyze the performance of your system. ? When you run a scenario, data is stored in a result (.lrr) file. ? Analysis is the utility that processes the gathered result information and generates graphs and reports. ? Analysis graphs are generated for the resources that were monitored during the scenario execution. 41 Mercury Tools LoadRunner Analysis ? When you work with the Analysis utility, you work within a session. ? An Analysis session contains at least one set of scenario results (.lrr file). ? Analysis stores the display information and layout settings for the active graphs in a .lra file. 42 Mercury Tools References ? ? ?
