Functions ¶
func GetBlockProfileRate ¶ added in v0.9.0
func GetBlockProfileRate() int
GetBlockProfileRate returns the current rate of goroutine blocking profile.
func GetMutexProfileFraction ¶ added in v0.9.0
func GetMutexProfileFraction() int
GetMutexProfileFraction returns the current fraction of mutexes that generate profile data.
func IsRunning ¶ added in v0.9.0
func IsRunning() bool
IsRunning returns true if the profiler is running; this function is thread-safe.
func SetBlockProfileRate ¶ added in v0.9.0
func SetBlockProfileRate(rate int)
SetBlockProfileRate sets goroutine blocking profile rate.
func SetMutexProfileFraction ¶ added in v0.9.0
func SetMutexProfileFraction(fraction int)
SetMutexProfileFraction sets fraction of mutexes that generate profiling data.
Types ¶
type Settings ¶ added in v0.9.0
type Settings struct {
// Site specifies the datadog site (datadoghq.com, datadoghq.eu, etc.) which profiles will be sent to.
Site string
// Env specifies the environment to which profiles should be registered.
Env string
// Service specifies the service name to attach to a profile.
Service string
// Period specifies the interval at which to collect profiles.
Period time.Duration
// CPUDuration specifies the length at which to collect CPU profiles.
CPUDuration time.Duration
// MutexProfileFraction, if set, turns on mutex profiles with rate
// indicating the fraction of mutex contention events reported in the mutex
// profile.
MutexProfileFraction int
// BlockProfileRate turns on block profiles with the given rate.
BlockProfileRate int
// WithGoroutineProfile additionally reports stack traces of all current goroutines
WithGoroutineProfile bool
// Tags are the additional tags to attach to profiles.
Tags []string
}
Settings contains the settings for internal profiling, to be passed to Start().
