Documentation

Overview

Package instance provides the functions required to manage the life-cycle of a Beat. It provides the standard mechanism for launching a Beat. It manages configuration, logging, and publisher initialization and registers a signal handler to gracefully stop the process.

Each Beat implementation must implement the `Beater` interface and a `Creator` to create and initialize the Beater instance. See the `Beater` interface and `Creator` documentation for more details.

To use this package, create a simple main that invokes the Run() function.

func main() {
	if err := beat.Run("mybeat", myVersion, beater.New); err != nil {
		os.Exit(1)
	}
}

In the example above, the beater package contains the implementation of the Beater interface and the New method returns a new instance of Beater. The Beater implementation is placed into its own package so that it can be reused or combined with other Beats.

Recommendations

  • Use the logp package for logging rather than writing to stdout or stderr.
  • Do not call os.Exit in any of your code. Return an error instead. Or if your code needs to exit without an error, return beat.GracefulExit.
