KVM_GETLOADAVG(3) DragonFly Library Functions Manual KVM_GETLOADAVG(3)
NAME
kvm_getloadavg -- get load average of the system
LIBRARY
Kernel Data Access Library (libkvm, -lkvm)
SYNOPSIS
#include <sys/types.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 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.
DIAGNOSTICS
If the load average was unobtainable, -1 is returned; otherwise, the num-
ber of samples actually retrieved is returned.
