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().
