func CaptureRuntimeMemStatsOnce

Defined in


Capture new values for the Go runtime statistics exported in runtime.MemStats. This is designed to be called in a background goroutine. Giving a registry which has not been given to RegisterRuntimeMemStats will panic.

Be very careful with this because runtime.ReadMemStats calls the C functions runtime·semacquire(&runtime·worldsema) and runtime·stoptheworld() and that last one does what it says on the tin.
