KVM_GETLOADAVG(3)         OpenBSD Programmer's Manual        KVM_GETLOADAVG(3)

NAME

     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.
