kvm_getloadavg - get load average of the system
SYNOPSIS
#include <sys/resource.h>
#include <kvm.h>
int
kvm_getloadavg(kvm_t *kd, double loadavg[], int nelem);
DESCRIPTION
The kvm_getloadavg() function returns the number of processes in the
system run queue of the kernel indicated by kd, 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.
RETURN VALUES
If the load average was unobtainable, -1 is returned. Otherwise, the
number of samples actually retrieved is returned.
