Load Impact v3.0 - Lua User Scenario Recorder
NOTE: Only for v3.0 product (not available to new users since Feb 1st 2019). There's another extension available in the web store for Load Impact v4.0. The extension records all of the HTTP(S) requests that your browser makes, creates a script, and automatically uploads it to your Load Impact account, where a load test can be executed with just one click. Once uploaded to your Load Impact account, you can edit the script using the simple but powerful high-level language Lua, which includes code completion and inline documentation. Using Load Impact’s service you can run up to 10 different users scenarios in each load test, simulating up to 1.2M concurrent users. You can also run the multiple user scenarios simultaneously from up to 10 different geographic regions in a single test (powered by Amazon and Rackspace). And you can use those scenarios to stress test your servers - Web, Application and Database - using Load Impact’s unique Server Metrics Agent. This will give you information such as: CPU usage, memory usage, disk I/O, network I/O, and any other data given by the 3000+ Nagios plug-ins.
