Update to use go modules (#671)
This includes updates to CI config, vendor files, etc. I've hard-coded the k8s depedency at 1.13.4 to keep it inline with what we currently have and to make sure a another run of `go mod tidy` doesn't accidentally update it to an unexpected version. Thanks to hectorj2f for carrying this along.

# Logrus <img src="http://i.imgur.com/hTeVwmJ.png" width="40" height="40" alt=":walrus:" class="emoji" title=":walrus:"/> [](https://travis-ci.org/sirupsen/logrus) [](https://godoc.org/github.com/sirupsen/logrus)
|
||||
|
||||
Logrus is a structured logger for Go (golang), completely API compatible with
|
||||
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
|
||||
username dot com`.
|
||||
|
||||
Nicely color-coded in development (when a TTY is attached, otherwise just
|
||||
plain text):
|
||||
|
||||
|
||||
|
||||
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
|
||||
```
|
||||
To ensure this behaviour even if a TTY is attached, set your formatter as follows:
|
||||
|
||||
```go
|
||||
log.SetFormatter(&log.TextFormatter{
|
||||
DisableColors: true,
|
||||
FullTimestamp: true,
|
||||
})
|
||||
```
|
||||
|
||||
#### Logging Method Name
|
||||
|
||||
If you wish to add the calling method as a field, instruct the logger via:
|
||||
```go
|
||||
log.SetReportCaller(true)
|
||||
```
|
||||
This adds the caller as 'method' like so:
|
||||
|
||||
```json
|
||||
{"animal":"penguin","level":"fatal","method":"github.com/sirupsen/arcticcreatures.migrate","msg":"a penguin swims by",
|
||||
"time":"2014-03-10 19:57:38.562543129 -0400 EDT"}
|
||||
```
|
||||
|
||||
```text
|
||||
time="2015-03-26T01:27:38-04:00" level=fatal method=github.com/sirupsen/arcticcreatures.migrate msg="a penguin swims by" animal=penguin
|
||||
```
|
||||
Note that this does add measurable overhead - the cost will depend on the version of Go, but is
|
||||
between 20 and 40% in recent tests with 1.6 and 1.7. You can validate this in your
|
||||
environment via benchmarks:
|
||||
```
|
||||
go test -bench=.*CallerTracing
|
||||
```
|
||||
|
||||
|
||||
#### Case-sensitivity
|
||||
|
||||
The organization's name was changed to lower-case--and this will not be changed
|
||||
back. If you are getting import conflicts due to case sensitivity, please use
|
||||
the lower-case import: `github.com/sirupsen/logrus`.
|
||||
|
||||
#### 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
|
||||
// Can be any io.Writer, see below for File example
|
||||
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 (
|
||||
"os"
|
||||
"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.Stdout
|
||||
|
||||
// You could set this to any `io.Writer` such as a file
|
||||
// file, err := os.OpenFile("logrus.log", os.O_CREATE|os.O_WRONLY, 0666)
|
||||
// if err == nil {
|
||||
// log.Out = file
|
||||
// } else {
|
||||
// log.Info("Failed to log to file, using default stderr")
|
||||
// }
|
||||
|
||||
log.WithFields(logrus.Fields{
|
||||
"animal": "walrus",
|
||||
"size": 10,
|
||||
}).Info("A group of walrus emerges from the ocean")
|
||||
}
|
||||
```
|
||||
|
||||
#### Fields
|
||||
|
||||
Logrus encourages careful, structured logging through 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.
|
||||
|
||||
#### 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
|
||||
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 "airbrake"
|
||||
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).
|
||||
|
||||
A list of currently known of service hook can be found in this wiki [page](https://github.com/sirupsen/logrus/wiki/Hooks)
|
||||
|
||||
|
||||
#### Level logging
|
||||
|
||||
Logrus has seven logging levels: Trace, Debug, Info, Warning, Error, Fatal and Panic.
|
||||
|
||||
```go
|
||||
log.Trace("Something very low level.")
|
||||
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`. For Windows, see
|
||||
[github.com/mattn/go-colorable](https://github.com/mattn/go-colorable).
|
||||
* When colors are enabled, levels are truncated to 4 characters by default. To disable
|
||||
truncation set the `DisableLevelTruncation` field to `true`.
|
||||
* All options are listed in the [generated docs](https://godoc.org/github.com/sirupsen/logrus#TextFormatter).
|
||||
* `logrus.JSONFormatter`. Logs fields as JSON.
|
||||
* All options are listed in the [generated docs](https://godoc.org/github.com/sirupsen/logrus#JSONFormatter).
|
||||
|
||||
Third party logging formatters:
|
||||
|
||||
* [`FluentdFormatter`](https://github.com/joonix/log). Formats entries that can be parsed by Kubernetes and Google Container Engine.
|
||||
* [`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).
|
||||
* [`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!̣͔̲̻͊̄ ̙̘̦̹̦.
|
||||
* [`nested-logrus-formatter`](https://github.com/antonfisher/nested-logrus-formatter). Converts logrus fields to a nested structure.
|
||||
|
||||
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`.
|
||||
|
||||
This means that we can override the standard library logger easily:
|
||||
|
||||
```go
|
||||
logger := logrus.New()
|
||||
logger.Formatter = &logrus.JSONFormatter{}
|
||||
|
||||
// Use logrus for standard log output
|
||||
// Note that `log` here references stdlib's log
|
||||
// Not logrus imported under the name `log`.
|
||||
log.SetOutput(logger.Writer())
|
||||
```
|
||||
|
||||
#### 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 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) |
|
||||
|
||||
#### 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
|
||||
import(
|
||||
"github.com/sirupsen/logrus"
|
||||
"github.com/sirupsen/logrus/hooks/test"
|
||||
"github.com/stretchr/testify/assert"
|
||||
"testing"
|
||||
)
|
||||
|
||||
func TestSomething(t*testing.T){
|
||||
logger, hook := test.NewNullLogger()
|
||||
logger.Error("Helloerror")
|
||||
|
||||
assert.Equal(t, 1, len(hook.Entries))
|
||||
assert.Equal(t, logrus.ErrorLevel, hook.LastEntry().Level)
|
||||
assert.Equal(t, "Helloerror", hook.LastEntry().Message)
|
||||
|
||||
hook.Reset()
|
||||
assert.Nil(t, 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 a mutex for concurrent writes. The mutex is held 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)
