Set Up Profiling
Go Profiling is currently in alpha. Alpha features are still in progress and may have bugs. We recognize the irony.
With profiling, Sentry tracks your software's performance by sampling your program's call stack in a variety of environments. This feature collects function-level information about your code and enables you to fine-tune your program's performance. Sentry's profiler captures function calls and their exact locations, aggregates them, and shows you the most common code paths of your program. This highlights areas you could optimize to help increase both the performance of your code and increase user satisfaction, as well as drive down costs.
Enable Performance Monitoring
Profiling depends on Sentry’s performance monitoring product being enabled beforehand. To enable performance monitoring in the SDK:
err := sentry.Init(sentry.ClientOptions{
Dsn: "https://examplePublicKey@o0.ingest.sentry.io/0",
EnableTracing: true,
// We recommend adjusting this value in production:
TracesSampleRate: 1.0,
})
Check out the performance setup documentation for more detailed information on how to configure sampling. Setting the sample rate to 1.0 means all transactions will be captured.
Enable Profiling
Go Profiling alpha is available since SDK version 0.22.0
.
To enable profiling, set the ProfilesSampleRate
:
err := sentry.Init(sentry.ClientOptions{
Dsn: "https://examplePublicKey@o0.ingest.sentry.io/0",
EnableTracing: true,
// We recommend adjusting these values in production:
TracesSampleRate: 1.0,
// The sampling rate for profiling is relative to TracesSampleRate:
ProfilesSampleRate: 1.0,
})
Our documentation is open source and available on GitHub. Your contributions are welcome, whether fixing a typo (drat!) or suggesting an update ("yeah, this would be better").
