11.2.4 profile Probe Creation

Unlike other providers, the profile provider creates probes dynamically on an as-needed basis. Thus, the desired probe might not appear in a listing of all probes, for example, when using the dtrace -l -P profile command, but the probe is created when it is explicitly enabled.

A time interval that is too short causes the machine to continuously field time-based interrupts and denies service on the machine. The profile provider silently refuses to create a probe that would result in an interval of less than two hundred microseconds.
