KVM_GETLOADAVG(3) Library Functions Manual KVM_GETLOADAVG(3) NAME kvm_getloadavg - get system load averages, from live or dead kernels LIBRARY Kernel Data Access Library (libkvm, -lkvm) SYNOPSIS #include <sys/resource.h> #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 or core file, indicated by kd. 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. On a live system, the load average is obtained by calling getloadavg(3). If performing post mortem on a kernel core file, kvm_getloadavg is able to extract the system load averages at the time of death from the core file directly. RETURN VALUES If the load average was unobtainable, -1 is returned; otherwise, the number of samples actually retrieved is returned.
