KVM_GETLOADAVG(3) DragonFly Library Functions Manual KVM_GETLOADAVG(3)
kvm_getloadavg -- get load average of the system
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 sys-
tem run queue of the kernel indicated by kd, averaged over various peri-
ods of time. Up to nelem samples are retrieved and assigned to succes-
sive 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 num-
ber of samples actually retrieved is returned.
