Logrus formatter for App Engine

This package provides logrus formatter for programs running on Google App Engine. It formats entries printed to stdout/stderr as JSON in a way that allows logging infrastructure to extract meaningful bits of information from them: uses predefined field names, maps severity levels to those expected etc.

Example

import (
	// ...

	log "github.com/sirupsen/logrus"
	"github.com/gelraen/appengine-formatter"
)

func main() {
	// ...

	log.SetReportCaller(true)  // optional, but highly recommended
	log.SetFormatter(&appengine.Formatter{
		TrimFilenamePrefix: appengine.SourceFileLocation(),
	})

	log.Printf("Listening on port %s", port)
	// ...
}

Resulting log entry looks like this:
