GETLOADAVG(3) FreeBSD Library Functions Manual GETLOADAVG(3)
NAME
getloadavg - get system load averages
SYNOPSIS
#include <stdlib.h>
_int getloadavg(double loadavg[], int nelem)
DESCRIPTION
The getloadavg() function returns the number of processes in the system
run queue 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 num-
ber of samples actually retrieved is returned.
SEE ALSO
uptime(1), kvm_getloadavg(3), sysctl(3)
HISTORY
The getloadavg() function appeared in 4.3BSD-Reno.
