|  | 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 |
