To apply a timer after a sampler, add the Constant Timer as a child element of. If you want to store the accessToken value into a JMeter property for using in other Thread Group(s) be aware that properties are global for the whole JVM and remain until JMeter is restarted so if you define a single accessToken property - each JMeter Thread (or iteration) will overwrite the value. A flow control action is an action that: Does not need a contact or a participant to succeed. Thread behaviour is defined according to ramp up and destroyed once the number of iterations per thread has elapsed. This sampler can also be useful in conjunction with the Transaction Controller, as it allows pauses to be included without needing to generate a sample. Overall, JMeter samplers are an essential component of load testing and performance testing. This will start the JMeter proxy server which is used to intercept the browser requests. In Windows you can do something like Invoke-WindowsApi "kernel32" ( [bool]) "DebugActiveProcess" @ ( [int]) @ (JMETER_PID). bat. 0 and 60K+ other titles, with a free 10-day trial of O'Reilly.
