The profile-
probes fire at a fixed interval, at a high-interrupt level on
all active CPUs. The units of n
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.

Suffix | Time Units |
---|---|
| nanoseconds |
| microseconds |
| milliseconds |
| seconds |
| minutes |
| hours |
| days |
