You can customize it all you +want: + +```go +package main + +import ( + "os" + log "github.com/Sirupsen/logrus" +) + +func init() { + // Log as JSON instead of the default ASCII formatter. + log.SetFormatter(&log.JSONFormatter{}) + + // Output to stderr instead of stdout, could also be a file. + log.SetOutput(os.Stderr) + + // Only log the warning severity or above. + log.SetLevel(log.WarnLevel) +} + +func main() { + log.WithFields(log.Fields{ + "animal": "walrus", + "size": 10, + }).Info("A group of walrus emerges from the ocean") + + log.WithFields(log.Fields{ + "omg": true, + "number": 122, + }).Warn("The group's number increased tremendously!") + + log.WithFields(log.Fields{ + "omg": true, + "number": 100, + }).Fatal("The ice breaks!") + + // A common pattern is to re-use fields between logging statements by re-using + // the logrus.Entry returned from WithFields() + contextLogger := log.WithFields(log.Fields{ + "common": "this is a common field", + "other": "I also should be logged always", + }) + + contextLogger.Info("I'll be logged with common and other field") + contextLogger.Info("Me too") +} +``` + +For more advanced usage such as logging to multiple locations from the same +application, you can also create an instance of the `logrus` Logger: + +```go +package main + +import ( + "github.com/Sirupsen/logrus" +) + +// Create a new instance of the logger. You can have any number of instances. +var log = logrus.New() + +func main() { + // The API for setting attributes is a little different than the package level + // exported logger. See Godoc. + log.Out = os.Stderr + + log.WithFields(logrus.Fields{ + "animal": "walrus", + "size": 10, + }).Info("A group of walrus emerges from the ocean") +} +``` + +#### Fields + +Logrus encourages careful, structured logging though logging fields instead of +long, unparseable error messages. For example, instead of: `log.Fatalf("Failed +to send event %s to topic %s with key %d")`, you should log the much more +discoverable: + +```go +log.WithFields(log.Fields{ + "event": event, + "topic": topic, + "key": key, +}).Fatal("Failed to send event") +``` + +We've found this API forces you to think about logging in a way that produces +much more useful logging messages. We've been in countless situations where just +a single added field to a log statement that was already there would've saved us +hours. The `WithFields` call is optional. + +In general, with Logrus using any of the `printf`-family functions should be +seen as a hint you should add a field, however, you can still use the +`printf`-family functions with Logrus. + +#### Hooks + +You can add hooks for logging levels. For example to send errors to an exception +tracking service on `Error`, `Fatal` and `Panic`, info to StatsD or log to +multiple places simultaneously, e.g. syslog. + +Logrus comes with [built-in hooks](hooks/). Add those, or your custom hook, in +`init`: + +```go +import ( + log "github.com/Sirupsen/logrus" + "gopkg.in/gemnasium/logrus-airbrake-hook.v2" // the package is named "aibrake" + logrus_syslog "github.com/Sirupsen/logrus/hooks/syslog" + "log/syslog" +) + +func init() { + + // Use the Airbrake hook to report errors that have Error severity or above to + // an exception tracker. You can create custom hooks, see the Hooks section. + log.AddHook(airbrake.NewHook(123, "xyz", "production")) + + hook, err := logrus_syslog.NewSyslogHook("udp", "localhost:514", syslog.LOG_INFO, "") + if err != nil { + log.Error("Unable to connect to local syslog daemon") + } else { + log.AddHook(hook) + } +} +``` +Note: Syslog hook also support connecting to local syslog (Ex. "/dev/log" or "/var/run/syslog" or "/var/run/log"). For the detail, please check the [syslog hook README](hooks/syslog/README.md). + +| Hook | Description | +| ----- | ----------- | +| [Airbrake](https://github.com/gemnasium/logrus-airbrake-hook) | Send errors to the Airbrake API V3.

Default. +log.SetLevel(log.InfoLevel) +``` + +It may be useful to set `log.Level = logrus.DebugLevel` in a debug or verbose +environment if your application has that. + +#### Entries + +Besides the fields added with `WithField` or `WithFields` some fields are +automatically added to all logging events: + +1. `time`. The timestamp when the entry was created. +2. `msg`. The logging message passed to `{Info,Warn,Error,Fatal,Panic}` after + the `AddFields` call. E.g. `Failed to send event.` +3. `level`. The logging level. E.g. `info`. + +#### Environments + +Logrus has no notion of environment. + +If you wish for hooks and formatters to only be used in specific environments, +you should handle that yourself. For example, if your application has a global +variable `Environment`, which is a string representation of the environment you +could do: + +```go +import ( + log "github.com/Sirupsen/logrus" +) + +init() { + // do something here to set environment depending on an environment variable + // or command-line flag + if Environment == "production" { + log.SetFormatter(&log.JSONFormatter{}) + } else { + // The TextFormatter is default, you don't actually have to do this. + log.SetFormatter(&log.TextFormatter{}) + } +} +``` + +This configuration is how `logrus` was intended to be used, but JSON in +production is mostly only useful if you do log aggregation with tools like +Splunk or Logstash. + +#### Formatters + +The built-in logging formatters are: + +* `logrus.TextFormatter`. Logs the event in colors if stdout is a tty, otherwise + without colors. + * *Note:* to force colored output when there is no TTY, set the `ForceColors` + field to `true`. To force no colored output even if there is a TTY set the + `DisableColors` field to `true` +* `logrus.JSONFormatter`. Logs fields as JSON. +* `logrus/formatters/logstash.LogstashFormatter`. Logs fields as [Logstash](http://logstash.net) Events. + + ```go + logrus.SetFormatter(&logstash.LogstashFormatter{Type: "application_name"}) + ``` + +Third party logging formatters: + +* [`prefixed`](https://github.com/x-cray/logrus-prefixed-formatter). Displays log entry source along with alternative layout. +* [`zalgo`](https://github.com/aybabtme/logzalgo). Invoking the PÍÌ«o̳̼ÌwÌÍÌ°Íe̬ÍÌÍrÍ̼̹̲ Ì«ÍÍ̳ÍÅÌ ÍÍÌfÌÍÌ Í̲ÌÍÍZÌ̫̤̫ͪaÍ̬ÍÌlÍÍg̳̥oÌ°Ì¥Ì !Ì£Í̲̻ÍÌ ÌÌ̦̹̦. + +You can define your formatter by implementing the `Formatter` interface, +requiring a `Format` method. `Format` takes an `*Entry`. `entry.Data` is a +`Fields` type (`map[string]interface{}`) with all your fields as well as the +default ones (see Entries section above): + +```go +type MyJSONFormatter struct { +} + +log.SetFormatter(new(MyJSONFormatter)) + +func (f *MyJSONFormatter) Format(entry *Entry) ([]byte, error) { + // Note this doesn't include Time, Level and Message which are available on + // the Entry. Consult `godoc` on information about those fields or read the + // source of the official loggers. + serialized, err := json.Marshal(entry.Data) + if err != nil { + return nil, fmt.Errorf("Failed to marshal fields to JSON, %v", err) + } + return append(serialized, '\n'), nil +} +``` + +#### Logger as an `io.Writer` + +Logrus can be transformed into an `io.Writer`. That writer is the end of an `io.Pipe` and it is your responsibility to close it. + +```go +w := logger.Writer() +defer w.Close() + +srv := http.Server{ + // create a stdlib log.Logger that writes to + // logrus.Logger. + ErrorLog: log.New(w, "", 0), +} +``` + +Each line written to that writer will be printed the usual way, using formatters +and hooks. The level for those entries is `info`. + +#### Rotation + +Log rotation is not provided with Logrus. Log rotation should be done by an +external program (like `logrotate(8)`) that can compress and delete old log +entries. It should not be a feature of the application-level logger. + +#### Tools + +| Tool | Description | +| ---- | ----------- | +|[Logrus Mate](https://github.com/gogap/logrus_mate)|Logrus mate is a tool for Logrus to manage loggers, you can initial logger's level, hook and formatter by config file, the logger will generated with different config at different environment.| + +#### Testing + +Logrus has a built in facility for asserting the presence of log messages.
