Quick Start¶

Python:

import googlecloudprofiler

googlecloudprofiler.start(
    service='my-service',

require('@google-cloud/profiler').start({
  serviceContext: {
    service: 'my-service',
    version: '1.0.0'
  }
});

Go:

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

if err := profiler.Start(profiler.Config{
    Service:        "my-service",
    ServiceVersion: "1.0.0",
}); err != nil {
    log.Fatal(err)
}

Best Practices¶

✓ Enable in production
✓ Use meaningful service names
✓ Include version information
