kvm_getloadavg -- get system load averages
Kernel Data Access Library (libkvm, -lkvm)
kvm_getloadavg(kvm_t *kd, double loadavg, int nelem);
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 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 actu-
ally retrieved is returned.
