11.2.1 profile-n Probes

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.

Table 11.1 Valid Time Suffixes

Suffix	Time Units
`nsec` or `ns`	nanoseconds
`usec` or `us`	microseconds
`msec` or `ms`	milliseconds
`sec` or `s`	seconds
`min` or `m`	minutes
`hour` or `h`	hours
`day` or `d`	days
`hz`	hertz (frequency expressed as rate per second)
