Functions

func AddBytesRead

func AddBytesRead(n int64)

func AddBytesWritten

func AddBytesWritten(n int64)

func FlushProcessCounters

func FlushProcessCounters(command string, subcommand string) error

func IncBlockDecode

func IncBlockDecode()

func IncContainerAppend

func IncContainerAppend()

func IncContainerClose

func IncContainerClose()

func IncContainerOpen

func IncContainerOpen()

func IncFsync

func StartOperation

func StartOperation()

StartOperation resets in-process metrics so captured counters are scoped to one command execution rather than cumulative process lifetime totals.
