11.2.1 profile-n Probes

The profile-n probes fire at a fixed interval, at a high-interrupt level on all active CPUs. The units of n default to a frequency that is 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. The following table describes valid time suffixes for a tick-n probe.
