/*
Package logrus is a structured logger for Go, completely API compatible with the standard library logger.
The simplest way to use Logrus is simply the package-level exported logger:
package main
import (
log "github.com/Sirupsen/logrus"
)
func main() {
log.WithFields(log.Fields{
"animal": "walrus",
"number": 1,
"size": 10,
}).Info("A walrus appears")
}
Output:
time="2015-09-07T08:48:33Z" level=info msg="A walrus appears" animal=walrus number=1 size=10
