GETLOADAVG(3) Linux Programmer's Manual GETLOADAVG(3)
NAME
getloadavg - get system load averages
SYNOPSIS
#define _BSD_SOURCE
#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 sam-
ples 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.
RETURN VALUE
If the load average was unobtainable, -1 is returned; otherwise, the number of samples actually retrieved is returned.
VERSIONS
This function is available in glibc since version 2.2.
CONFORMING TO
Not in POSIX.1-2001. Present on the BSDs and Solaris.
