This glossary defines some of the terms that are used in the ARM DS-5 Streamline User Guide.
A backtrace is a snapshot of a thread's call stack at a specific moment in time.
- Call stack unwinding
A counter counts how often a particular event occurs. Counters are read on a schedule switch and on a sample.
- Event-based sampling (EBS)
A sample is when the running thread is interrupted and a backtrace is collected. When event-based sampling (EBS) is not enabled, a sample is collected a fixed number of times per second as specified by the sample rate. When EBS is enabled, a sample should be taken when the count of the counter is a multiple of the count specified.
