A backtrace is a snapshot of a thread's call stack at a specific moment in time.

Call stack unwinding

See Backtrace.


A counter counts how often a particular event occurs. Counters are read on a schedule switch and on a sample.

Event-based sampling (EBS)

See Sample.


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.
