KVM_GETLOADAVG(3)          Library Functions Manual          KVM_GETLOADAVG(3)

NAME
     kvm_getloadavg - get system load averages, from live or dead kernels

LIBRARY
     Kernel Data Access Library (libkvm, -lkvm)

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 or core file, indicated by kd.  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.  On a live
     system, the load average is obtained by calling getloadavg(3).  If
     performing post mortem on a kernel core file, kvm_getloadavg is able to
     extract the system load averages at the time of death from the core file
     directly.

RETURN VALUES
     If the load average was unobtainable, -1 is returned; otherwise, the
     number of samples actually retrieved is returned.
