11.2.1 profile-n Probes

profile-n probes fire at a fixed interval at high-interrupt level on all active CPUs. The units of n default to a frequency expressed as a rate of firing per second, but the value can also have an optional suffix as shown in Table 11.1, “Valid Time Suffixes”, which specifies either a time interval or a frequency.
