kvm_getloadavg3
Get load average of the system
Usage
#include <kvm.h>
int
kvm_getloadavg(kvm_t *kd, double loadavg[], int nelem);
Library
Kernel Data Access Library (libkvm, -lkvm)
Overview
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.
