KVM_GETLOADAVG(3)
KVM_GETLOADAVG(3) FreeBSD Library Functions Manual KVM_GETLOADAVG(3)

NAME

kvm_getloadavgget load average of the system

LIBRARY

Kernel Data Access Library (libkvm, -lkvm)

SYNOPSIS

#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.

DIAGNOSTICS

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