Formatter for logrus, allowing log entries to be recognized by the fluentd Stackdriver agent on Google Cloud Platform.

Example:

package main

import (
	"time"
	"net/http"

	log "github.com/sirupsen/logrus"
	joonix "github.com/joonix/log"
)

func main() {
	log.SetFormatter(joonix.NewFormatter())
	log.Info("hello world!")

	// log a HTTP request in your handler
	log.WithField("httpRequest", &joonix.HTTPRequest{
		Request: r,
		Status: http.StatusOK,
		ResponseSize: 31337,
		Latency: 123*time.Millisecond,
	}).Info("additional info")
}

• https://github.com/knq/sdhook (implemented as a hook, doesn't require fluentd)
• #2 (you can map the format yourself)

It is possible to run the google edition of fluentd a.k.a. stackdriver agent outside of GCP, just a bit tricky to configure. See following references for more info:
