Section (3) getloadavg
getloadavg — get system load averages
returns the number of processes in the system run queue
averaged over various periods of time. Up to
nelem samples are retrieved and
assigned to successive elements of
loadavg. The system imposes a
maximum of 3 samples, representing averages over the last 1,
5, and 15 minutes, respectively.
If the load average was unobtainable, −1 is returned; otherwise, the number of samples actually retrieved is returned.
For an explanation of the terms used in this section, see attributes(7).
