type CPUInfoStat ¶
type CPUInfoStat struct {
CPU int32 `json:"cpu"`
VendorID string `json:"vendor_id"`
Family string `json:"family"`
Model string `json:"model"`
Stepping int32 `json:"stepping"`
PhysicalID string `json:"physical_id"`
CoreID string `json:"core_id"`
Cores int32 `json:"cores"`
ModelName string `json:"model_name"`
Mhz float64 `json:"mhz"`
CacheSize int32 `json:"cache_size"`
Flags []string `json:"flags"`
}
func CPUInfo ¶
func CPUInfo() ([]CPUInfoStat, error)
CPUInfo on linux will return 1 item per physical thread.
CPUs have three levels of counting: sockets, cores, threads. Cores with HyperThreading count as having 2 threads per core. Sockets often come with many physical CPU cores. For example a single socket board with two cores each with HT will return 4 CPUInfoStat structs on Linux and the "Cores" field set to 1.
func (CPUInfoStat) String ¶
func (c CPUInfoStat) String() string
type CPUTimesStat ¶
type CPUTimesStat struct {
CPU string `json:"cpu"`
User uint64 `json:"user"`
System uint64 `json:"system"`
Idle uint64 `json:"idle"`
Nice uint64 `json:"nice"`
Iowait uint64 `json:"iowait"`
Irq uint64 `json:"irq"`
Softirq uint64 `json:"softirq"`
Steal uint64 `json:"steal"`
Guest uint64 `json:"guest"`
GuestNice uint64 `json:"guest_nice"`
Stolen uint64 `json:"stolen"`
}
