Functions

func CPUProfile

func CPUProfile(ctx context.Context, sec int) ([]byte, map[string]string, error)

CPUProfile generates a CPU Profile for a given duration

func Cmdline

func Cmdline() ([]byte, map[string]string, error)

Cmdline responds with the running program's command line, with arguments separated by NUL bytes.

func IsErrProfileNotFound

func IsErrProfileNotFound(err error) bool

IsErrProfileNotFound returns whether the error is due to a pprof profile being invalid

func NewErrProfileNotFound

func NewErrProfileNotFound(profile string) error

NewErrProfileNotFound returns a new error caused by a pprof.Lookup profile not being found

func Profile

func Profile(profile string, debug, gc int) ([]byte, map[string]string, error)

Profile generates a pprof.Profile report for the given profile name see runtime/pprof/pprof.go for available profiles.

func Trace

func Trace(ctx context.Context, sec int) ([]byte, map[string]string, error)

Trace runs a trace profile for a given duration
