|
||||
|
||||
**Seeing weird case-sensitive problems?** See [this
|
||||
issue](https://github.com/sirupsen/logrus/issues/451#issuecomment-264332021).
|
||||
This change has been reverted. I apologize for causing this. I greatly
|
||||
underestimated the impact this would have. Logrus strives for stability and
|
||||
backwards compatibility and failed to provide that.
|
||||
|
||||
Logrus is a structured logger for Go (golang), completely API compatible with
|
||||
the standard library logger. [Godoc][godoc]. **Please note the Logrus API is not
|
||||
yet stable (pre 1.0). Logrus itself is completely stable and has been used in
|
||||
many large deployments. The core API is unlikely to change much but please
|
||||
version control your Logrus to make sure you aren't fetching latest `master` on
|
||||
every build.**
|
||||
|
||||
Nicely color-coded in development (when a TTY is attached, otherwise just
|
||||
plain text):
|
||||
|
||||
![Colored](http://i.imgur.com/PY7qMwd.png)
|
||||
|
||||
With `log.SetFormatter(&log.JSONFormatter{})`, for easy parsing by logstash
|
||||
or Splunk:
|
||||
|
||||
```json
|
||||
{"animal":"walrus","level":"info","msg":"A group of walrus emerges from the
|
||||
ocean","size":10,"time":"2014-03-10 19:57:38.562264131 -0400 EDT"}
|
||||
|
||||
{"level":"warning","msg":"The group's number increased tremendously!",
|
||||
"number":122,"omg":true,"time":"2014-03-10 19:57:38.562471297 -0400 EDT"}
|
||||
|
||||
{"animal":"walrus","level":"info","msg":"A giant walrus appears!",
|
||||
"size":10,"time":"2014-03-10 19:57:38.562500591 -0400 EDT"}
|
||||
|
||||
{"animal":"walrus","level":"info","msg":"Tremendously sized cow enters the ocean.",
|
||||
"size":9,"time":"2014-03-10 19:57:38.562527896 -0400 EDT"}
|
||||
|
||||
{"level":"fatal","msg":"The ice breaks!","number":100,"omg":true,
|
||||
"time":"2014-03-10 19:57:38.562543128 -0400 EDT"}
|
||||
```
|
||||
|
||||
With the default `log.SetFormatter(&log.TextFormatter{})` when a TTY is not
|
||||
attached, the output is compatible with the
|
||||
[logfmt](http://godoc.org/github.com/kr/logfmt) format:
|
||||
|
||||
```text
|
||||
time="2015-03-26T01:27:38-04:00" level=debug msg="Started observing beach" animal=walrus number=8
|
||||
time="2015-03-26T01:27:38-04:00" level=info msg="A group of walrus emerges from the ocean" animal=walrus size=10
|
||||
time="2015-03-26T01:27:38-04:00" level=warning msg="The group's number increased tremendously!" number=122 omg=true
|
||||
time="2015-03-26T01:27:38-04:00" level=debug msg="Temperature changes" temperature=-4
|
||||
time="2015-03-26T01:27:38-04:00" level=panic msg="It's over 9000!" animal=orca size=9009
|
||||
time="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
|
||||
exit status 1
|
||||
```
|
||||
|
||||
#### Example
|
||||
|
||||
The simplest way to use Logrus is simply the package-level exported logger:
|
||||
|
||||
```go
|
||||
package main
|
||||
|
||||
import (
|
||||
log "github.com/Sirupsen/logrus"
|
||||
)
|
||||
|
||||
func main() {
|
||||
log.WithFields(log.Fields{
|
||||
"animal": "walrus",
|
||||
}).Info("A walrus appears")
|
||||
}
|
||||
```
|
||||
|
||||
Note that it's completely api-compatible with the stdlib logger, so you can
|
||||
replace your `log` imports everywhere with `log "github.com/Sirupsen/logrus"`
|
||||
and you'll now have the flexibility of Logrus. 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 stdout instead of the default stderr, could also be a file.
|
||||
log.SetOutput(os.Stdout)
|
||||
|
||||
// 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).

||||
|
||||
#### Level logging
|
||||
|
||||
Logrus has six logging levels: Debug, Info, Warning, Error, Fatal and Panic.
|
||||
|
||||
```go
|
||||
log.Debug("Useful debugging information.")
|
||||
log.Info("Something noteworthy happened!")
|
||||
log.Warn("You should probably take a look at this.")
|
||||
log.Error("Something failed but I'm not quitting.")
|
||||
// Calls os.Exit(1) after logging
|
||||
log.Fatal("Bye.")
|
||||
// Calls panic() after logging
|
||||
log.Panic("I'm bailing.")
|
||||
```
|
||||
|
||||
You can set the logging level on a `Logger`, then it will only log entries with
|
||||
that severity or anything above it:
|
||||
|
||||
```go
|
||||
// Will log anything that is info or above (warn, error, fatal, panic). 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.
|
||||
|
||||
Third party logging formatters:
|
||||
|
||||
* [`logstash`](https://github.com/bshuster-repo/logrus-logstash-hook). Logs fields as [Logstash](http://logstash.net) Events.
|
||||
* [`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 P͉̫o̳̼̊w̖͈̰͎e̬͔̭͂r͚̼̹̲ ̫͓͉̳͈ō̠͕͖̚f̝͍̠ ͕̲̞͖͑Z̖̫̤̫ͪa͉̬͈̗l͖͎g̳̥o̰̥̅!̣͔̲̻͊̄ ̙̘̦̹̦.
|
||||
|
||||
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.|
|
||||
|[Logrus Viper Helper](https://github.com/heirko/go-contrib/tree/master/logrusHelper)|An Helper arround 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) |
|
||||
|
||||
#### Testing
|
||||
|
||||
Logrus has a built in facility for asserting the presence of log messages. This is implemented through the `test` hook and provides:
|
||||
|
||||
* decorators for existing logger (`test.NewLocal` and `test.NewGlobal`) which basically just add the `test` hook
|
||||
* a test logger (`test.NewNullLogger`) that just records log messages (and does not output any):
|
||||
|
||||
```go
|
||||
logger, hook := NewNullLogger()
|
||||
logger.Error("Hello error")
|
||||
|
||||
assert.Equal(1, len(hook.Entries))
|
||||
assert.Equal(logrus.ErrorLevel, hook.LastEntry().Level)
|
||||
assert.Equal("Hello error", hook.LastEntry().Message)
|
||||
|
||||
hook.Reset()
|
||||
assert.Nil(hook.LastEntry())
|
||||
```
|
||||
|
||||
#### Fatal handlers
|
||||
|
||||
Logrus can register one or more functions that will be called when any `fatal`
|
||||
level message is logged. The registered handlers will be executed before
|
||||
logrus performs a `os.Exit(1)`. This behavior may be helpful if callers need
|
||||
to 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.
|
||||
|
||||
```
|
||||
...
|
||||
handler := func() {
|
||||
// gracefully shutdown something...
|
||||
}
|
||||
logrus.RegisterExitHandler(handler)
|
||||
...
|
||||
```
|
||||
|
||||
#### Thread safety
|
||||
|
||||
By default Logger is protected by mutex for concurrent writes, this mutex is invoked when calling hooks and writing logs.
|
||||
If you are sure such locking is not needed, you can call logger.SetNoLock() to disable the locking.
|
||||
|
||||
Situation when locking is not needed includes:
|
||||
|
||||
* You have no hooks registered, or hooks calling is already thread-safe.
|
||||
|
||||
* Writing to logger.Out is already thread-safe, for example:
|
||||
|
||||
1) logger.Out is protected by locks.
|
||||
|
||||
2) logger.Out is a os.File handler opened with `O_APPEND` flag, and every write is smaller than 4k. (This allow multi-thread/multi-process writing)

# Syslog Hooks for Logrus <img src="http://i.imgur.com/hTeVwmJ.png" width="40" height="40" alt=":walrus:" class="emoji" title=":walrus:"/>
|
||||
|
||||
## Usage
|
||||
|
||||
```go
|
||||
import (
|
||||
"log/syslog"
|
||||
"github.com/Sirupsen/logrus"
|
||||
logrus_syslog "github.com/Sirupsen/logrus/hooks/syslog"
|
||||
)
|
||||
|
||||
func main() {
|
||||
log := logrus.New()
|
||||
hook, err := logrus_syslog.NewSyslogHook("udp", "localhost:514", syslog.LOG_INFO, "")
|
||||
|
||||
if err == nil {
|
||||
log.Hooks.Add(hook)
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
If you want to connect to local syslog (Ex. "/dev/log" or "/var/run/syslog" or "/var/run/log"). Just assign empty string to the first two parameters of `NewSyslogHook`. It should look like the following.
|
||||
|
||||
```go
|
||||
import (
|
||||
"log/syslog"
|
||||
"github.com/Sirupsen/logrus"
|
||||
logrus_syslog "github.com/Sirupsen/logrus/hooks/syslog"
|
||||
)
|
||||
|
||||
func main() {
|
||||
log := logrus.New()
|
||||
hook, err := logrus_syslog.NewSyslogHook("", "", syslog.LOG_INFO, "")
|
||||
|
||||
if err == nil {
|
||||
log.Hooks.Add(hook)
|
||||
}

Logrus is a structured logger for Go (golang), completely API compatible with
|
||||
the standard library logger. [Godoc][godoc]. **Please note the Logrus API is not
|
||||
yet stable (pre 1.0). Logrus itself is completely stable and has been used in
|
||||
many large deployments. The core API is unlikely to change much but please
|
||||
version control your Logrus to make sure you aren't fetching latest `master` on
|
||||
every build.**
|
||||
the standard library logger.
|
||||
|
||||
**Seeing weird case-sensitive problems?** It's in the past been possible to
|
||||
import Logrus as both upper- and lower-case. Due to the Go package environment,
|
||||
this caused issues in the community and we needed a standard. Some environments
|
||||
experienced problems with the upper-case variant, so the lower-case was decided.
|
||||
Everything using `logrus` will need to use the lower-case:
|
||||
`github.com/sirupsen/logrus`. Any package that isn't, should be changed.
|
||||
|
||||
To fix Glide, see [these
|
||||
comments](https://github.com/sirupsen/logrus/issues/553#issuecomment-306591437).
|
||||
For an in-depth explanation of the casing issue, see [this
|
||||
comment](https://github.com/sirupsen/logrus/issues/570#issuecomment-313933276).
|
||||
|
||||
**Are you interested in assisting in maintaining Logrus?** Currently I have a
|
||||
lot of obligations, and I am unable to provide Logrus with the maintainership it
|
||||
needs. If you'd like to help, please reach out to me at `simon at author's
|

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:

requestLogger := log.WithFields(log.Fields{"request_id": request_id, "user_ip": user_ip})
