SYNOPSIS
#include <sys/resource.h>

kvm_getloadavg(kvm_t *kd, double loadavg[], int nelem);
DESCRIPTION
The kvm_getloadavg() function returns the number of processes in the sys‐
tem run queue of the kernel indicated by kd, averaged over various peri‐
ods of time. Up to nelem samples are retrieved and assigned to succes‐
sive 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 num‐
ber of samples actually retrieved is returned.
