+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
