Variables

var CurrentPID = os.Getpid()

CurrentPID returns the process id of the caller.

Functions

func GetCPUNum

func GetCPUNum() int

GetCPUNum gets current os's cpu number

func GetCgroupMemoryLimit

func GetCgroupMemoryLimit() (uint64, error)

GetCgroupMemoryLimit returns a container's total memory in bytes

func GetCgroupProcessMemoryPercent

func GetCgroupProcessMemoryPercent() (float64, error)

GetCgroupProcessMemoryPercent gets current process's memory usage percent in cgroup env

func GetGoroutineNum

func GetGoroutineNum() int

GetGoroutineNum gets current process's goroutine number

func GetMemoryStat

func GetMemoryStat() (total, used, free uint64, usedPercent float64)

GetMemoryStat gets current os's memory size in bytes

func GetProcessCPUStat

func GetProcessCPUStat() (float64, error)

GetProcessCPUStat gets current process's cpu stat

func GetProcessMemoryPercent

func GetProcessMemoryPercent() (float32, error)

GetProcessMemoryStat gets current process's memory usage percent

func GetProcessMemoryStat

func GetProcessMemoryStat() (uint64, error)

GetProcessMemoryStat gets current process's memory usage in Byte

func GetThreadNum

func GetThreadNum() int

GetThreadNum gets current process's thread number

func GoSafely

func GoSafely(wg *sync.WaitGroup, ignoreRecover bool, handler func(), catchFunc func(r interface{}))

GoSafely wraps a `go func()` with recover()

func GoUnterminated

func GoUnterminated(handle func(), wg *sync.WaitGroup, ignoreRecover bool, period time.Duration)

GoUnterminated is used for which goroutine wanna long live as its process. @period: sleep time duration after panic to defeat @handle panic so frequently. if it is not positive,

the @handle will be invoked asap after panic.

func IsCgroup

func IsCgroup() bool

IsCgroup checks whether current os is a container or not
