1# Logrus <img src="http://i.imgur.com/hTeVwmJ.png" width="40" height="40" alt=":walrus:" class="emoji" title=":walrus:"/> [![Build Status](https://github.com/sirupsen/logrus/workflows/CI/badge.svg)](https://github.com/sirupsen/logrus/actions?query=workflow%3ACI) [![Build Status](https://travis-ci.org/sirupsen/logrus.svg?branch=master)](https://travis-ci.org/sirupsen/logrus) [![Go Reference](https://pkg.go.dev/badge/github.com/sirupsen/logrus.svg)](https://pkg.go.dev/github.com/sirupsen/logrus)
2
3Logrus is a structured logger for Go (golang), completely API compatible with
4the standard library logger.
5
6**Logrus is in maintenance-mode.** We will not be introducing new features. It's
7simply too hard to do in a way that won't break many people's projects, which is
8the last thing you want from your Logging library (again...).
9
10This does not mean Logrus is dead. Logrus will continue to be maintained for
11security, (backwards compatible) bug fixes, and performance (where we are
12limited by the interface).
13
14I believe Logrus' biggest contribution is to have played a part in today's
15widespread use of structured logging in Golang. There doesn't seem to be a
16reason to do a major, breaking iteration into Logrus V2, since the fantastic Go
17community has built those independently. Many fantastic alternatives have sprung
18up. Logrus would look like those, had it been re-designed with what we know
19about structured logging in Go today. Check out, for example,
20[Zerolog][zerolog], [Zap][zap], and [Apex][apex].
21
22[zerolog]: https://github.com/rs/zerolog
23[zap]: https://github.com/uber-go/zap
24[apex]: https://github.com/apex/log
25
26**Seeing weird case-sensitive problems?** It's in the past been possible to
27import Logrus as both upper- and lower-case. Due to the Go package environment,
28this caused issues in the community and we needed a standard. Some environments
29experienced problems with the upper-case variant, so the lower-case was decided.
30Everything using `logrus` will need to use the lower-case:
31`github.com/sirupsen/logrus`. Any package that isn't, should be changed.
32
33To fix Glide, see [these
34comments](https://github.com/sirupsen/logrus/issues/553#issuecomment-306591437).
35For an in-depth explanation of the casing issue, see [this
36comment](https://github.com/sirupsen/logrus/issues/570#issuecomment-313933276).
37
38Nicely color-coded in development (when a TTY is attached, otherwise just
39plain text):
40
41![Colored](http://i.imgur.com/PY7qMwd.png)
42
43With `log.SetFormatter(&log.JSONFormatter{})`, for easy parsing by logstash
44or Splunk:
45
46```text
47{"animal":"walrus","level":"info","msg":"A group of walrus emerges from the
48ocean","size":10,"time":"2014-03-10 19:57:38.562264131 -0400 EDT"}
49
50{"level":"warning","msg":"The group's number increased tremendously!",
51"number":122,"omg":true,"time":"2014-03-10 19:57:38.562471297 -0400 EDT"}
52
53{"animal":"walrus","level":"info","msg":"A giant walrus appears!",
54"size":10,"time":"2014-03-10 19:57:38.562500591 -0400 EDT"}
55
56{"animal":"walrus","level":"info","msg":"Tremendously sized cow enters the ocean.",
57"size":9,"time":"2014-03-10 19:57:38.562527896 -0400 EDT"}
58
59{"level":"fatal","msg":"The ice breaks!","number":100,"omg":true,
60"time":"2014-03-10 19:57:38.562543128 -0400 EDT"}
61```
62
63With the default `log.SetFormatter(&log.TextFormatter{})` when a TTY is not
64attached, the output is compatible with the
65[logfmt](http://godoc.org/github.com/kr/logfmt) format:
66
67```text
68time="2015-03-26T01:27:38-04:00" level=debug msg="Started observing beach" animal=walrus number=8
69time="2015-03-26T01:27:38-04:00" level=info msg="A group of walrus emerges from the ocean" animal=walrus size=10
70time="2015-03-26T01:27:38-04:00" level=warning msg="The group's number increased tremendously!" number=122 omg=true
71time="2015-03-26T01:27:38-04:00" level=debug msg="Temperature changes" temperature=-4
72time="2015-03-26T01:27:38-04:00" level=panic msg="It's over 9000!" animal=orca size=9009
73time="2015-03-26T01:27:38-04:00" level=fatal msg="The ice breaks!" err=&{0x2082280c0 map[animal:orca size:9009] 2015-03-26 01:27:38.441574009 -0400 EDT panic It's over 9000!} number=100 omg=true
74```
75To ensure this behaviour even if a TTY is attached, set your formatter as follows:
76
77```go
78 log.SetFormatter(&log.TextFormatter{
79 DisableColors: true,
80 FullTimestamp: true,
81 })
82```
83
84#### Logging Method Name
85
86If you wish to add the calling method as a field, instruct the logger via:
87```go
88log.SetReportCaller(true)
89```
90This adds the caller as 'method' like so:
91
92```json
93{"animal":"penguin","level":"fatal","method":"github.com/sirupsen/arcticcreatures.migrate","msg":"a penguin swims by",
94"time":"2014-03-10 19:57:38.562543129 -0400 EDT"}
95```

100Note that this does add measurable overhead - the cost will depend on the version of Go, but is
101between 20 and 40% in recent tests with 1.6 and 1.7. You can validate this in your
102environment via benchmarks:
103```
104go test -bench=.*CallerTracing
105```
106
107
108#### Case-sensitivity
109
110The organization's name was changed to lower-case--and this will not be changed
111back. If you are getting import conflicts due to case sensitivity, please use
112the lower-case import: `github.com/sirupsen/logrus`.
113
114#### Example
115
116The simplest way to use Logrus is simply the package-level exported logger:
117
118```go
119package main
120
121import (
122 log "github.com/sirupsen/logrus"
123)
124
125func main() {
126 log.WithFields(log.Fields{
127 "animal": "walrus",
128 }).Info("A walrus appears")
129}
130```
131
132Note that it's completely api-compatible with the stdlib logger, so you can
133replace your `log` imports everywhere with `log "github.com/sirupsen/logrus"`
134and you'll now have the flexibility of Logrus. You can customize it all you
135want:
136
137```go
138package main
139
140import (
141 "os"
142 log "github.com/sirupsen/logrus"
143)
144
145func init() {
146 // Log as JSON instead of the default ASCII formatter.
147 log.SetFormatter(&log.JSONFormatter{})
148
149 // Output to stdout instead of the default stderr
150 // Can be any io.Writer, see below for File example
151 log.SetOutput(os.Stdout)
152
153 // Only log the warning severity or above.
154 log.SetLevel(log.WarnLevel)
155}
156
157func main() {
158 log.WithFields(log.Fields{
159 "animal": "walrus",
160 "size": 10,
161 }).Info("A group of walrus emerges from the ocean")
162
163 log.WithFields(log.Fields{
164 "omg": true,
165 "number": 122,
166 }).Warn("The group's number increased tremendously!")
167
168 log.WithFields(log.Fields{
169 "omg": true,
170 "number": 100,
171 }).Fatal("The ice breaks!")
172
173 // A common pattern is to re-use fields between logging statements by re-using
174 // the logrus.Entry returned from WithFields()
175 contextLogger := log.WithFields(log.Fields{
176 "common": "this is a common field",
177 "other": "I also should be logged always",
178 })
179
180 contextLogger.Info("I'll be logged with common and other field")
181 contextLogger.Info("Me too")
182}
183```
184
185For more advanced usage such as logging to multiple locations from the same
186application, you can also create an instance of the `logrus` Logger:
187
188```go
189package main
190
191import (
192 "os"
193 "github.com/sirupsen/logrus"
194)
195
196// Create a new instance of the logger. You can have any number of instances.
197var log = logrus.New()
198
199func main() {
200 // The API for setting attributes is a little different than the package level
201 // exported logger. See Godoc.
202 log.Out = os.Stdout
203
204 // You could set this to any `io.Writer` such as a file
205 // file, err := os.OpenFile("logrus.log", os.O_CREATE|os.O_WRONLY|os.O_APPEND, 0666)
206 // if err == nil {
207 // log.Out = file
208 // } else {
209 // log.Info("Failed to log to file, using default stderr")
210 // }
211
212 log.WithFields(logrus.Fields{
213 "animal": "walrus",
214 "size": 10,
215 }).Info("A group of walrus emerges from the ocean")
216}
217```
218
219#### Fields
220
221Logrus encourages careful, structured logging through logging fields instead of
222long, unparseable error messages. For example, instead of: `log.Fatalf("Failed
223to send event %s to topic %s with key %d")`, you should log the much more
224discoverable:
225
226```go
227log.WithFields(log.Fields{
228 "event": event,
229 "topic": topic,
230 "key": key,
231}).Fatal("Failed to send event")
232```
233
234We've found this API forces you to think about logging in a way that produces
235much more useful logging messages. We've been in countless situations where just
236a single added field to a log statement that was already there would've saved us
237hours. The `WithFields` call is optional.
238
239In general, with Logrus using any of the `printf`-family functions should be
240seen as a hint you should add a field, however, you can still use the
241`printf`-family functions with Logrus.
242
243#### Default Fields
244
245Often it's helpful to have fields _always_ attached to log statements in an
246application or parts of one. For example, you may want to always log the
247`request_id` and `user_ip` in the context of a request. Instead of writing
248`log.WithFields(log.Fields{"request_id": request_id, "user_ip": user_ip})` on
249every line, you can create a `logrus.Entry` to pass around instead:
250
251```go
252requestLogger := log.WithFields(log.Fields{"request_id": request_id, "user_ip": user_ip})
253requestLogger.Info("something happened on that request") # will log request_id and user_ip
254requestLogger.Warn("something not great happened")
255```
256
257#### Hooks
258
259You can add hooks for logging levels. For example to send errors to an exception
260tracking service on `Error`, `Fatal` and `Panic`, info to StatsD or log to
261multiple places simultaneously, e.g. syslog.
262
263Logrus comes with [built-in hooks](hooks/). Add those, or your custom hook, in
264`init`:
265
266```go
267import (
268 log "github.com/sirupsen/logrus"
269 "gopkg.in/gemnasium/logrus-airbrake-hook.v2" // the package is named "airbrake"
270 logrus_syslog "github.com/sirupsen/logrus/hooks/syslog"
271 "log/syslog"
272)
273
274func init() {
275
276 // Use the Airbrake hook to report errors that have Error severity or above to
277 // an exception tracker. You can create custom hooks, see the Hooks section.
278 log.AddHook(airbrake.NewHook(123, "xyz", "production"))
279
280 hook, err := logrus_syslog.NewSyslogHook("udp", "localhost:514", syslog.LOG_INFO, "")
281 if err != nil {
282 log.Error("Unable to connect to local syslog daemon")
283 } else {
284 log.AddHook(hook)
285 }
286}
287```
288Note: 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).
289
290A list of currently known service hooks can be found in this wiki [page](https://github.com/sirupsen/logrus/wiki/Hooks)
291
292
293#### Level logging
294
295Logrus has seven logging levels: Trace, Debug, Info, Warning, Error, Fatal and Panic.
296
297```go
298log.Trace("Something very low level.")
299log.Debug("Useful debugging information.")
300log.Info("Something noteworthy happened!")
301log.Warn("You should probably take a look at this.")
302log.Error("Something failed but I'm not quitting.")
303// Calls os.Exit(1) after logging
304log.Fatal("Bye.")
305// Calls panic() after logging
306log.Panic("I'm bailing.")
307```
308
309You can set the logging level on a `Logger`, then it will only log entries with
310that severity or anything above it:
311
312```go
313// Will log anything that is info or above (warn, error, fatal, panic). Default.
314log.SetLevel(log.InfoLevel)
315```
316
317It may be useful to set `log.Level = logrus.DebugLevel` in a debug or verbose
318environment if your application has that.
319
320Note: If you want different log levels for global (`log.SetLevel(...)`) and syslog logging, please check the [syslog hook README](hooks/syslog/README.md#different-log-levels-for-local-and-remote-logging).
321
322#### Entries
323
324Besides the fields added with `WithField` or `WithFields` some fields are
325automatically added to all logging events:
326
3271. `time`. The timestamp when the entry was created.
3282. `msg`. The logging message passed to `{Info,Warn,Error,Fatal,Panic}` after
329 the `AddFields` call. E.g. `Failed to send event.`
3303. `level`. The logging level. E.g. `info`.
331
332#### Environments
333
334Logrus has no notion of environment.
335
336If you wish for hooks and formatters to only be used in specific environments,
337you should handle that yourself. For example, if your application has a global
338variable `Environment`, which is a string representation of the environment you
339could do:
340
341```go
342import (
343 log "github.com/sirupsen/logrus"
344)
345
346func init() {
347 // do something here to set environment depending on an environment variable
348 // or command-line flag
349 if Environment == "production" {
350 log.SetFormatter(&log.JSONFormatter{})
351 } else {
352 // The TextFormatter is default, you don't actually have to do this.
353 log.SetFormatter(&log.TextFormatter{})
354 }
355}
356```
357
358This configuration is how `logrus` was intended to be used, but JSON in
359production is mostly only useful if you do log aggregation with tools like
360Splunk or Logstash.
361
362#### Formatters
363
364The built-in logging formatters are:
365
366* `logrus.TextFormatter`. Logs the event in colors if stdout is a tty, otherwise
367 without colors.
368 * *Note:* to force colored output when there is no TTY, set the `ForceColors`
369 field to `true`. To force no colored output even if there is a TTY set the
370 `DisableColors` field to `true`. For Windows, see
371 [github.com/mattn/go-colorable](https://github.com/mattn/go-colorable).
372 * When colors are enabled, levels are truncated to 4 characters by default. To disable
373 truncation set the `DisableLevelTruncation` field to `true`.
374 * When outputting to a TTY, it's often helpful to visually scan down a column where all the levels are the same width. Setting the `PadLevelText` field to `true` enables this behavior, by adding padding to the level text.
375 * All options are listed in the [generated docs](https://godoc.org/github.com/sirupsen/logrus#TextFormatter).
376* `logrus.JSONFormatter`. Logs fields as JSON.
377 * All options are listed in the [generated docs](https://godoc.org/github.com/sirupsen/logrus#JSONFormatter).
378
379Third party logging formatters:
380
381* [`FluentdFormatter`](https://github.com/joonix/log). Formats entries that can be parsed by Kubernetes and Google Container Engine.
382* [`GELF`](https://github.com/fabienm/go-logrus-formatters). Formats entries so they comply to Graylog's [GELF 1.1 specification](http://docs.graylog.org/en/2.4/pages/gelf.html).
383* [`logstash`](https://github.com/bshuster-repo/logrus-logstash-hook). Logs fields as [Logstash](http://logstash.net) Events.
384* [`prefixed`](https://github.com/x-cray/logrus-prefixed-formatter). Displays log entry source along with alternative layout.
385* [`zalgo`](https://github.com/aybabtme/logzalgo). Invoking the Power of Zalgo.
386* [`nested-logrus-formatter`](https://github.com/antonfisher/nested-logrus-formatter). Converts logrus fields to a nested structure.
387* [`powerful-logrus-formatter`](https://github.com/zput/zxcTool). get fileName, log's line number and the latest function's name when print log; Sava log to files.
388* [`caption-json-formatter`](https://github.com/nolleh/caption_json_formatter). logrus's message json formatter with human-readable caption added.
389
390You can define your formatter by implementing the `Formatter` interface,
391requiring a `Format` method. `Format` takes an `*Entry`. `entry.Data` is a
392`Fields` type (`map[string]interface{}`) with all your fields as well as the
393default ones (see Entries section above):
394
395```go
396type MyJSONFormatter struct {
397}
398
399log.SetFormatter(new(MyJSONFormatter))
400
401func (f *MyJSONFormatter) Format(entry *Entry) ([]byte, error) {
402 // Note this doesn't include Time, Level and Message which are available on
403 // the Entry. Consult `godoc` on information about those fields or read the
404 // source of the official loggers.
405 serialized, err := json.Marshal(entry.Data)
406 if err != nil {
407 return nil, fmt.Errorf("Failed to marshal fields to JSON, %w", err)
408 }
409 return append(serialized, '\n'), nil
410}
411```
412
413#### Logger as an `io.Writer`
414
415Logrus can be transformed into an `io.Writer`. That writer is the end of an `io.Pipe` and it is your responsibility to close it.
416
417```go
418w := logger.Writer()
419defer w.Close()
420
421srv := http.Server{
422 // create a stdlib log.Logger that writes to
423 // logrus.Logger.
424 ErrorLog: log.New(w, "", 0),
425}
426```
427
428Each line written to that writer will be printed the usual way, using formatters
429and hooks. The level for those entries is `info`.
430
431This means that we can override the standard library logger easily:
432
433```go
434logger := logrus.New()
435logger.Formatter = &logrus.JSONFormatter{}
436
437// Use logrus for standard log output
438// Note that `log` here references stdlib's log
439// Not logrus imported under the name `log`.
440log.SetOutput(logger.Writer())
441```
442
443#### Rotation
444
445Log rotation is not provided with Logrus. Log rotation should be done by an
446external program (like `logrotate(8)`) that can compress and delete old log
447entries. It should not be a feature of the application-level logger.
448
449#### Tools
450
451| Tool | Description |
452| ---- | ----------- |
453|[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 be generated with different configs in different environments.|
454|[Logrus Viper Helper](https://github.com/heirko/go-contrib/tree/master/logrusHelper)|An Helper around Logrus to wrap with spf13/Viper to load configuration with fangs! And to simplify Logrus configuration use some behavior of [Logrus Mate](https://github.com/gogap/logrus_mate). [sample](https://github.com/heirko/iris-contrib/blob/master/middleware/logrus-logger/example) |
455
456#### Testing
457
458Logrus has a built in facility for asserting the presence of log messages. This is implemented through the `test` hook and provides:
459
460* decorators for existing logger (`test.NewLocal` and `test.NewGlobal`) which basically just adds the `test` hook
461* a test logger (`test.NewNullLogger`) that just records log messages (and does not output any):
462
463```go
464import(
465 "github.com/sirupsen/logrus"
466 "github.com/sirupsen/logrus/hooks/test"
467 "github.com/stretchr/testify/assert"
468 "testing"
469)
470
471func TestSomething(t*testing.T){
472 logger, hook := test.NewNullLogger()
473 logger.Error("Helloerror")
474
475 assert.Equal(t, 1, len(hook.Entries))
476 assert.Equal(t, logrus.ErrorLevel, hook.LastEntry().Level)
477 assert.Equal(t, "Helloerror", hook.LastEntry().Message)
478
479 hook.Reset()
480 assert.Nil(t, hook.LastEntry())
481}
482```
483
484#### Fatal handlers
485
486Logrus can register one or more functions that will be called when any `fatal`
487level message is logged. The registered handlers will be executed before
488logrus performs an `os.Exit(1)`. This behavior may be helpful if callers need
489to gracefully shutdown. Unlike a `panic("Something went wrong...")` call which can be intercepted with a deferred `recover` a call to `os.Exit(1)` can not be intercepted.
490
491```
492...
493handler := func() {
494 // gracefully shutdown something...
495}
496logrus.RegisterExitHandler(handler)
497...
498```
499
500#### Thread safety
501
502By default, Logger is protected by a mutex for concurrent writes. The mutex is held when calling hooks and writing logs.
503If you are sure such locking is not needed, you can call logger.SetNoLock() to disable the locking.
504
505Situation when locking is not needed includes:
506
507* You have no hooks registered, or hooks calling is already thread-safe.
508
509* Writing to logger.Out is already thread-safe, for example:
510
511 1) logger.Out is protected by locks.
512
513 2) logger.Out is an os.File handler opened with `O_APPEND` flag, and every write is smaller than 4k. (This allows multi-thread/multi-process writing)
514

2Package logrus is a structured logger for Go, completely API compatible with the standard library logger.
3
4
5The simplest way to use Logrus is simply the package-level exported logger:
6
7 package main
8
9 import (
10 log "github.com/sirupsen/logrus"
11 )
12
13 func main() {
14 log.WithFields(log.Fields{
15 "animal": "walrus",
16 "number": 1,
17 "size": 10,
18 }).Info("A walrus appears")
19 }
20
21Output:
22 time="2015-09-07T08:48:33Z" level=info msg="A walrus appears" animal=walrus number=1 size=10
