profile Probe Creation

Unlike other providers, the profile provider creates probes dynamically based on the requirement. Thus, the desired profile probe might not appear in a listing of all probes but the probe will be created when it is explicitly enabled. You can use the dtrace -l -P profile to list all the probes.

On architectures that support arbitrary resolution profile probes, a time interval that is too short causes the system to continuously field time-based interrupts, thereby denying service on the system. To prevent this situation, the profile provider silently refuses to create any probe that would result in an interval of less than two hundred microseconds.
