       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.

       If the load average was unobtainable, -1 is returned; otherwise, the number of samples actually retrieved
       is returned.
