The total time taken INCLUDING times when the task is not executing is often called the "Response Time" of the task.

To obtain the "Observed" maximum response time, a filter should be constructed to find this value from the trace. RapiTime does not provide this automatically, but it can be extracted from the trace. An automatic way of providing this information is already on our roadmap.

The maximum theoretical response time (called "Worst Case Response Time", WCRT"), can be calculated using schedulability analysis. Schedulability analysis requires information about operating system overheads, blocking calls and scheduling policies.

Schedulability analysis also requires as its input, task worst-case execution time. These can be obtained using RapiTime.
