49.Sh DESCRIPTION
50The
51.Fn kvm_getloadavg
52function returns the number of processes in the system run queue
53of the kernel indicated by
54.Fa kd ,
55averaged over various periods of time.
56Up to
57.Fa nelem
58samples are retrieved and assigned to successive elements of
59.Fa loadavg Ns Bq .
60The system imposes a maximum of 3 samples, representing averages
61over the last 1, 5, and 15 minutes, respectively.
62.Sh DIAGNOSTICS
63If the load average was unobtainable, \-1 is returned; otherwise,
64the number of samples actually retrieved is returned.
