Logrus
Logrus is a structured logger for Go, used to log messages in different formats and levels. This guide demonstrates how to integrate Logrus with Sentry to capture and send logs to Sentry.
For a quick reference, there is a complete example at the Go SDK source code repository.
Go API documentation for the sentrylogrus package is also available.

logrus.RegisterExitHandler(func() { sentryHook.Flush(5 * time.Second) })
// Log an InfoLevel entry to STDERR (not sent to Sentry)
logger.Infof("Application has started")
// Log an ErrorLevel entry to STDERR and Sentry
logger.Errorf("oh no!")
// Log a FatalLevel entry to STDERR, send to Sentry, and terminate the application
logger.Fatalf("can't continue...")
sentrylogrus allows configuration via the New function, which accepts the levels to log and sentry.ClientOptions. The levels to log are the logrus levels that should be sent to Sentry. The sentry.ClientOptions are the same as the ones used in the sentry.Init function.
Use logrus as you normally would, and it will automatically send logs at or above the specified levels to Sentry.
