cloud.google.com/go/profiler (go): Package profiler is a client for the Cloud Profiler service.  Usage example:  Calling Start will start a goroutine to collect profiles and upload to the profiler server, at the rhythm specified by the server.  The caller must provide the service string in the config, and may provide other information as well. See Config for details.  Profiler has CPU, heap and goroutine profiling enabled by default. Mutex profiling can be enabled in the config. Note that goroutine and mutex profiles are shown as "threads" and "contention" profiles in the profiler UI.
