package profiler

import "cloud.google.com/go/profiler"

Package profiler is a client for the Google Cloud Profiler service.

This package is still experimental and subject to change.

Calling Start will start a goroutine to collect profiles and upload to Cloud Profiler server, at the rhythm specified by the server.

The caller should provide the target string in the config so Cloud Profiler knows how to group the profile data. Otherwise the target string is set to "unknown".

Optionally DebugLogging can be set in the config to enable detailed logging from profiler.

Start should only be called once. The first call will start the profiling goroutine. Any additional calls will be ignored.
