Switch Controller runs one of its children if name or index of the switch expression matches, otherwise it runs the first direct child. Add If Controller after this sampler and use the following __jexl3() expression: ${__jexl3(${code}==404,)} it means that If Controller's children will only be executed if the Sampler will fail with 404 status codeAlso check jmeter. When this checkbox is not activated, any condition used is evaluated in javascript by the IF controller. JMeter provides Synchronizing Timer which allows grouping requests so they could be executed at exactly in the same moment. Now add one or more samples to the controller.
