KVM_GETLOADAVG(3)					   BSD Library Functions Manual 					 KVM_GETLOADAVG(3)

NAME

     kvm_getloadavg -- get load average of the system

LIBRARY

     Kernel Data Access Library (libkvm, -lkvm)

SYNOPSIS

     #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 system run queue of the kernel indicated by kd, 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 sam-
     ples, 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.

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.
