NAME
getloadavg - get system load averages SYNOPSIS
getloadavg(loadavg, nelem) 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 number of samples actually retrieved is returned. SEE ALSO
uptime(1), sysctl(3), sysctl(8). HISTORY
The getloadavg function appeared in 4.3BSD-Reno. This function replaces the 2.9BSD compatibility routine getla(). 4th Berkeley Distribution January 15, 1995 GETLOADAVG(3)

NAME
getloadavg - get system load averages SYNOPSIS
#include <sys/loadavg.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. The LOADAVG_1MIN, LOADAVG_5MIN, and LOADAVG_15MIN indices, defined in <sys/loadavg.h>, can be used to extract the data from the appropriate element of the loadavg[] array. RETURN VALUES
Upon successful completion, the number of samples actually retrieved is returned. If the load average was unobtainable, -1 is returned and errno is set to indicate the error. ERRORS
The getloadavg() function will fail if: EINVAL The number of elements specified is less than 0. USAGE
If the caller is in a non-global zone and the pools facility is active, the behavior of getloadavg() is equivalent to that of pset_getload- avg(3C) called with psetid set to PS_MYID. ATTRIBUTES
