Functions ¶

func CheckExecutable ¶

func CheckExecutable(file string) error

func CheckFDLimitSupported ¶ added in v0.2.0

func CheckFDLimitSupported() bool

func CheckFileHandlesSupported ¶ added in v0.3.1

func CheckFileHandlesSupported() bool

Returns true if the file handles are supported.

func FindLibrary ¶ added in v0.0.5

func FindLibrary(name string, opts ...OpOption) (string, error)

func GetCurrentProcessUsage ¶ added in v0.4.0

func GetCurrentProcessUsage() (uint64, error)

Returns the number of allocated file handles for the current process.

func GetFileHandles ¶ added in v0.3.1

func GetFileHandles() (uint64, uint64, error)

Returns the number of allocated file handles and the number of allocated but unused file handles.

func GetLimit ¶ added in v0.2.0

func GetLimit() (uint64, error)

Returns the current file descriptor limit for the host, not for the current process. for the current process, use syscall.Getrlimit.

func GetUsage ¶ added in v0.2.0

func GetUsage() (uint64, error)

"process_open_fds" in prometheus collector ref. https://github.com/prometheus/client_golang/blob/main/prometheus/process_collector_other.go ref. https://pkg.go.dev/github.com/prometheus/procfs
