go-kit: Sample Code for Function to Log

func getLogger() log.Logger {
    var logger log.Logger
    logger = log.NewLogfmtLogger(log.NewSyncWriter(os.Stderr))
    logger = log.With(logger, "instance_id", 123)
    return logger

The above function is easily usable in a go-kit project to log JSON style data.

func myfun() {
    mylogger := getLogger()
    mylogger.Log("a key", "a value")
