40.Nd get load average of the system
41.Sh LIBRARY
42.Lb libkvm
43.Sh SYNOPSIS
44.In kvm.h
45.Ft int
46.Fn kvm_getloadavg "kvm_t *kd" "double loadavg[]" "int nelem"
47.Sh DESCRIPTION
48The
49.Fn kvm_getloadavg
50function returns the number of processes in the system run queue
51of the kernel indicated by
52.Fa kd ,
53averaged over various periods of time.
54Up to
55.Fa nelem
56samples are retrieved and assigned to successive elements of
57.Fa loadavg Ns Bq .
58The system imposes a maximum of 3 samples, representing averages
59over the last 1, 5, and 15 minutes, respectively.
60.Sh DIAGNOSTICS
61If the load average was unobtainable, \-1 is returned; otherwise,
62the number of samples actually retrieved is returned.
