seen as a hint you should add a field, however, you can still use the
`printf`-family functions with Logrus.
#### Default Fields
Often it's helpful to have fields _always_ attached to log statements in an
application or parts of one. For example, you may want to always log the
`request_id` and `user_ip` in the context of a request. Instead of writing
`log.WithFields(log.Fields{"request_id": request_id, "user_ip": user_ip})` on
every line, you can create a `logrus.Entry` to pass around instead:
```go
requestLogger := log.WithFields(log.Fields{"request_id": request_id, user_ip: user_ip})
requestLogger.Info("something happened on that request") # will log request_id and user_ip
requestLogger.Warn("something not great happened")
```
#### Hooks
You can add hooks for logging levels. For example to send errors to an exception
