# Logrus <img src="http://i.imgur.com/hTeVwmJ.png" width="40" height="40" alt=":walrus:" class="emoji" title=":walrus:"/>&nbsp;[![Build Status](https://travis-ci.org/Sirupsen/logrus.svg?branch=master)](https://travis-ci.org/Sirupsen/logrus)&nbsp;[![godoc reference](https://godoc.org/github.com/Sirupsen/logrus?status.png)][godoc]
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), the core API is unlikely 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.Formatter = new(logrus.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.Formatter = new(logrus.TextFormatter)` when a TTY is not
attached, the output is compatible with the
[l2met](http://r.32k.io/l2met-introduction) format:
```text
time="2014-04-20 15:36:23.830442383 -0400 EDT" level="info" msg="A group of walrus emerges from the ocean" animal="walrus" size=10
time="2014-04-20 15:36:23.830584199 -0400 EDT" level="warning" msg="The group's number increased tremendously!" omg=true number=122
time="2014-04-20 15:36:23.830596521 -0400 EDT" level="info" msg="A giant walrus appears!" animal="walrus" size=10
time="2014-04-20 15:36:23.830611837 -0400 EDT" level="info" msg="Tremendously sized cow enters the ocean." animal="walrus" size=9
time="2014-04-20 15:36:23.830626464 -0400 EDT" level="fatal" msg="The ice breaks!" omg=true number=100
```
#### 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"
"github.com/Sirupsen/logrus/hooks/airbrake"
)
func init() {
// Log as JSON instead of the default ASCII formatter.
log.SetFormatter(&log.JSONFormatter{})
// 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(&logrus_airbrake.AirbrakeHook{})
// 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!")
}
```
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.
```go
// Not the real implementation of the Airbrake hook. Just a simple sample.
import (
log "github.com/Sirupsen/logrus"
)
func init() {
log.AddHook(new(AirbrakeHook))
}
type AirbrakeHook struct{}
// `Fire()` takes the entry that the hook is fired for. `entry.Data[]` contains
// the fields for the entry. See the Fields section of the README.
func (hook *AirbrakeHook) Fire(entry *logrus.Entry) error {
err := airbrake.Notify(entry.Data["error"].(error))
if err != nil {
log.WithFields(log.Fields{
"source": "airbrake",
"endpoint": airbrake.Endpoint,
}).Info("Failed to send error to Airbrake")
}
return nil
}
// `Levels()` returns a slice of `Levels` the hook is fired for.
func (hook *AirbrakeHook) Levels() []log.Level {
return []log.Level{
log.ErrorLevel,
log.FatalLevel,
log.PanicLevel,
}
}
```
Logrus comes with built-in hooks. Add those, or your custom hook, in `init`:
```go
import (
log "github.com/Sirupsen/logrus"
"github.com/Sirupsen/logrus/hooks/airbrake"
"github.com/Sirupsen/logrus/hooks/syslog"
"log/syslog"
)
func init() {
log.AddHook(new(logrus_airbrake.AirbrakeHook))
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)
}
}
```
* [`github.com/Sirupsen/logrus/hooks/airbrake`](https://github.com/Sirupsen/logrus/blob/master/hooks/airbrake/airbrake.go)
Send errors to an exception tracking service compatible with the Airbrake API.
Uses [`airbrake-go`](https://github.com/tobi/airbrake-go) behind the scenes.
* [`github.com/Sirupsen/logrus/hooks/papertrail`](https://github.com/Sirupsen/logrus/blob/master/hooks/papertrail/papertrail.go)
Send errors to the Papertrail hosted logging service via UDP.
* [`github.com/Sirupsen/logrus/hooks/syslog`](https://github.com/Sirupsen/logrus/blob/master/hooks/syslog/syslog.go)
Send errors to remote syslog server.
Uses standard library `log/syslog` behind the scenes.
* [`github.com/nubo/hiprus`](https://github.com/nubo/hiprus)
Send errors to a channel in hipchat.
* [`github.com/sebest/logrusly`](https://github.com/sebest/logrusly)
Send logs to Loggly (https://www.loggly.com/)
* [`github.com/johntdyer/slackrus`](https://github.com/johntdyer/slackrus)
Hook for Slack chat.
#### 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(logrus.JSONFormatter)
} else {
// The TextFormatter is default, you don't actually have to do this.
log.SetFormatter(logrus.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:
* [`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 *JSONFormatter) 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
}
```
#### Rotation
Log rotation is not provided with Logrus. Log rotation should be done by an
external program (like `logrotated(8)`) that can compress and delete old log
entries. It should not be a feature of the application-level logger.

# Papertrail Hook for Logrus <img src="http://i.imgur.com/hTeVwmJ.png" width="40" height="40" alt=":walrus:" class="emoji" title=":walrus:" />
[Papertrail](https://papertrailapp.com) provides hosted log management. Once stored in Papertrail, you can [group](http://help.papertrailapp.com/kb/how-it-works/groups/) your logs on various dimensions, [search](http://help.papertrailapp.com/kb/how-it-works/search-syntax) them, and trigger [alerts](http://help.papertrailapp.com/kb/how-it-works/alerts).
In most deployments, you'll want to send logs to Papertrail via their [remote_syslog](http://help.papertrailapp.com/kb/configuration/configuring-centralized-logging-from-text-log-files-in-unix/) daemon, which requires no application-specific configuration. This hook is intended for relatively low-volume logging, likely in managed cloud hosting deployments where installing `remote_syslog` is not possible.
## Usage
You can find your Papertrail UDP port on your [Papertrail account page](https://papertrailapp.com/account/destinations). Substitute it below for `YOUR_PAPERTRAIL_UDP_PORT`.
For `YOUR_APP_NAME`, substitute a short string that will readily identify your application or service in the logs.
```go
import (
"log/syslog"
"github.com/Sirupsen/logrus"
"github.com/Sirupsen/logrus/hooks/papertrail"
)
func main() {
log := logrus.New()
hook, err := logrus_papertrail.NewPapertrailHook("logs.papertrailapp.com", YOUR_PAPERTRAIL_UDP_PORT, YOUR_APP_NAME)
if err == nil {
log.Hooks.Add(hook)
}

# Sentry Hook for Logrus <img src="http://i.imgur.com/hTeVwmJ.png" width="40" height="40" alt=":walrus:" class="emoji" title=":walrus:" />
[Sentry](https://getsentry.com) provides both self-hosted and hosted
solutions for exception tracking.
Both client and server are
[open source](https://github.com/getsentry/sentry).
## Usage
Every sentry application defined on the server gets a different
[DSN](https://www.getsentry.com/docs/). In the example below replace
`YOUR_DSN` with the one created for your application.
```go
import (
"github.com/Sirupsen/logrus"
"github.com/Sirupsen/logrus/hooks/sentry"
)
func main() {
log := logrus.New()
hook, err := logrus_sentry.NewSentryHook(YOUR_DSN, []logrus.Level{
logrus.PanicLevel,
logrus.FatalLevel,
logrus.ErrorLevel,
})
if err == nil {
log.Hooks.Add(hook)
}
}
```
## Special fields
Some logrus fields have a special meaning in this hook,
these are server_name and logger.
When logs are sent to sentry these fields are treated differently.
- server_name (also known as hostname) is the name of the server which
is logging the event (hostname.example.com)
- logger is the part of the application which is logging the event.
In go this usually means setting it to the name of the package.
## Timeout
`Timeout` is the time the sentry hook will wait for a response
from the sentry server.
If this time elapses with no response from
the server an error will be returned.
If `Timeout` is set to 0 the SentryHook will not wait for a reply
and will assume a correct delivery.
The SentryHook has a default timeout of `100 milliseconds` when created
with a call to `NewSentryHook`. This can be changed by assigning a value to the `Timeout` field:
```go
hook, _ := logrus_sentry.NewSentryHook(...)
hook.Timeout = 20*time.Seconds
```

2. License Grants and Conditions
2.1. Grants
Each Contributor hereby grants You a world-wide, royalty-free,
non-exclusive license:
a. under intellectual property rights (other than patent or trademark)
Licensable by such Contributor to use, reproduce, make available,
modify, display, perform, distribute, and otherwise exploit its
Contributions, either on an unmodified basis, with Modifications, or
as part of a Larger Work; and
b. under Patent Claims of such Contributor to make, use, sell, offer for
sale, have made, import, and otherwise transfer either its
Contributions or its Contributor Version.
2.2. Effective Date
The licenses granted in Section 2.1 with respect to any Contribution
become effective for each Contribution on the date the Contributor first
distributes such Contribution.
2.3. Limitations on Grant Scope
The licenses granted in this Section 2 are the only rights granted under
this License. No additional rights or licenses will be implied from the
distribution or licensing of Covered Software under this License.
Notwithstanding Section 2.1(b) above, no patent license is granted by a
Contributor:
a. for any code that a Contributor has removed from Covered Software; or
b. for infringements caused by: (i) Your and any other third party's
modifications of Covered Software, or (ii) the combination of its
Contributions with other software (except as part of its Contributor
Version); or
c. under Patent Claims infringed by Covered Software in the absence of
its Contributions.
This License does not grant any rights in the trademarks, service marks,
or logos of any Contributor (except as may be necessary to comply with
the notice requirements in Section 3.4).
2.4. Subsequent Licenses
No Contributor makes additional grants as a result of Your choice to
distribute the Covered Software under a subsequent version of this
License (see Section 10.2) or under the terms of a Secondary License (if
permitted under the terms of Section 3.3).
2.5. Representation
Each Contributor represents that the Contributor believes its
Contributions are its original creation(s) or it has sufficient rights to
grant the rights to its Contributions conveyed by this License.
2.6. Fair Use
This License is not intended to limit any rights You have under
applicable copyright doctrines of fair use, fair dealing, or other
equivalents.
2.7. Conditions
Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted in
Section 2.1.
3. Responsibilities
3.1. Distribution of Source Form
All distribution of Covered Software in Source Code Form, including any
Modifications that You create or to which You contribute, must be under
the terms of this License. You must inform recipients that the Source
Code Form of the Covered Software is governed by the terms of this
License, and how they can obtain a copy of this License. You may not
attempt to alter or restrict the recipients' rights in the Source Code
Form.
3.2. Distribution of Executable Form
If You distribute Covered Software in Executable Form then:
a. such Covered Software must also be made available in Source Code Form,
as described in Section 3.1, and You must inform recipients of the
Executable Form how they can obtain a copy of such Source Code Form by
reasonable means in a timely manner, at a charge no more than the cost
of distribution to the recipient; and
b. You may distribute such Executable Form under the terms of this
License, or sublicense it under different terms, provided that the
license for the Executable Form does not attempt to limit or alter the
recipients' rights in the Source Code Form under this License.
3.3. Distribution of a Larger Work
You may create and distribute a Larger Work under terms of Your choice,
provided that You also comply with the requirements of this License for
the Covered Software. If the Larger Work is a combination of Covered
Software with a work governed by one or more Secondary Licenses, and the
Covered Software is not Incompatible With Secondary Licenses, this
License permits You to additionally distribute such Covered Software
under the terms of such Secondary License(s), so that the recipient of
the Larger Work may, at their option, further distribute the Covered
Software under the terms of either this License or such Secondary
License(s).
3.4. Notices
You may not remove or alter the substance of any license notices
(including copyright notices, patent notices, disclaimers of warranty, or
limitations of liability) contained within the Source Code Form of the
Covered Software, except that You may alter any license notices to the
extent required to remedy known factual inaccuracies.
3.5. Application of Additional Terms
You may choose to offer, and to charge a fee for, warranty, support,
indemnity or liability obligations to one or more recipients of Covered
Software. However, You may do so only on Your own behalf, and not on
behalf of any Contributor. You must make it absolutely clear that any
such warranty, support, indemnity, or liability obligation is offered by
You alone, and You hereby agree to indemnify every Contributor for any
liability incurred by such Contributor as a result of warranty, support,
indemnity or liability terms You offer. You may include additional
disclaimers of warranty and limitations of liability specific to any
jurisdiction.
4. Inability to Comply Due to Statute or Regulation
If it is impossible for You to comply with any of the terms of this License
with respect to some or all of the Covered Software due to statute,
judicial order, or regulation then You must: (a) comply with the terms of
this License to the maximum extent possible; and (b) describe the
limitations and the code they affect. Such description must be placed in a
text file included with all distributions of the Covered Software under
this License. Except to the extent prohibited by statute or regulation,
such description must be sufficiently detailed for a recipient of ordinary
skill to be able to understand it.
5. Termination
5.1. The rights granted under this License will terminate automatically if You
fail to comply with any of its terms. However, if You become compliant,
then the rights granted under this License from a particular Contributor
are reinstated (a) provisionally, unless and until such Contributor
explicitly and finally terminates Your grants, and (b) on an ongoing
basis, if such Contributor fails to notify You of the non-compliance by
some reasonable means prior to 60 days after You have come back into
compliance. Moreover, Your grants from a particular Contributor are
reinstated on an ongoing basis if such Contributor notifies You of the
non-compliance by some reasonable means, this is the first time You have
received notice of non-compliance with this License from such
Contributor, and You become compliant prior to 30 days after Your receipt
of the notice.
5.2. If You initiate litigation against any entity by asserting a patent
infringement claim (excluding declaratory judgment actions,
counter-claims, and cross-claims) alleging that a Contributor Version
directly or indirectly infringes any patent, then the rights granted to
You by any and all Contributors for the Covered Software under Section
2.1 of this License shall terminate.
5.3. In the event of termination under Sections 5.1 or 5.2 above, all end user
license agreements (excluding distributors and resellers) which have been
validly granted by You or Your distributors under this License prior to
termination shall survive termination.
6. Disclaimer of Warranty
Covered Software is provided under this License on an "as is" basis,
without warranty of any kind, either expressed, implied, or statutory,
including, without limitation, warranties that the Covered Software is free
of defects, merchantable, fit for a particular purpose or non-infringing.
The entire risk as to the quality and performance of the Covered Software
is with You. Should any Covered Software prove defective in any respect,
You (not any Contributor) assume the cost of any necessary servicing,
repair, or correction. This disclaimer of warranty constitutes an essential
part of this License. No use of any Covered Software is authorized under
this License except under this disclaimer.
7. Limitation of Liability
Under no circumstances and under no legal theory, whether tort (including
negligence), contract, or otherwise, shall any Contributor, or anyone who
distributes Covered Software as permitted above, be liable to You for any
direct, indirect, special, incidental, or consequential damages of any
character including, without limitation, damages for lost profits, loss of
goodwill, work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses, even if such party shall have been
informed of the possibility of such damages. This limitation of liability
shall not apply to liability for death or personal injury resulting from
such party's negligence to the extent applicable law prohibits such
limitation. Some jurisdictions do not allow the exclusion or limitation of
incidental or consequential damages, so this exclusion and limitation may
not apply to You.
8. Litigation
Any litigation relating to this License may be brought only in the courts
of a jurisdiction where the defendant maintains its principal place of
business and such litigation shall be governed by laws of that
jurisdiction, without reference to its conflict-of-law provisions. Nothing
in this Section shall prevent a party's ability to bring cross-claims or
counter-claims.
9. Miscellaneous
This License represents the complete agreement concerning the subject
matter hereof. If any provision of this License is held to be
unenforceable, such provision shall be reformed only to the extent
necessary to make it enforceable. Any law or regulation which provides that
the language of a contract shall be construed against the drafter shall not
be used to construe this License against a Contributor.
10. Versions of the License
10.1. New Versions
Mozilla Foundation is the license steward. Except as provided in Section
10.3, no one other than the license steward has the right to modify or
publish new versions of this License. Each version will be given a
distinguishing version number.
10.2. Effect of New Versions
You may distribute the Covered Software under the terms of the version
of the License under which You originally received the Covered Software,
or under the terms of any subsequent version published by the license
steward.
10.3. Modified Versions
If you create software not governed by this License, and you want to
create a new license for such software, you may create and use a
modified version of this License if you rename the license and remove
any references to the name of the license steward (except to note that
such modified license differs from this License).
10.4. Distributing Source Code Form that is Incompatible With Secondary
Licenses If You choose to distribute Source Code Form that is
Incompatible With Secondary Licenses under the terms of this version of
the License, the notice described in Exhibit B of this License must be
attached.
Exhibit A - Source Code Form License Notice
This Source Code Form is subject to the
terms of the Mozilla Public License, v.
2.0. If a copy of the MPL was not
distributed with this file, You can
obtain one at
http://mozilla.org/MPL/2.0/.
If it is not possible or desirable to put the notice in a particular file,
then You may include the notice in a location (such as a LICENSE file in a
relevant directory) where a recipient would be likely to look for such a
notice.
You may add additional accurate notices of copyright ownership.
Exhibit B - "Incompatible With Secondary Licenses" Notice
This Source Code Form is "Incompatible
With Secondary Licenses", as defined by
the Mozilla Public License, v. 2.0.

consul-api
==========
This package provides the `consulapi` package which attempts to
provide programmatic access to the full Consul API.
Currently, all of the Consul APIs included in version 0.3 are supported.
Documentation
=============
The full documentation is available on [Godoc](http://godoc.org/github.com/armon/consul-api)
Usage
=====
Below is an example of using the Consul client:
```go
// Get a new client, with KV endpoints
client, _ := consulapi.NewClient(consulapi.DefaultConfig())
kv := client.KV()
// PUT a new KV pair
p := &consulapi.KVPair{Key: "foo", Value: []byte("test")}
_, err := kv.Put(p, nil)
if err != nil {
panic(err)
}
// Lookup the pair
pair, _, err := kv.Get("foo", nil)
if err != nil {
panic(err)
}
fmt.Printf("KV: %v", pair)
```

# backoff
[![GoDoc](https://godoc.org/github.com/cenkalti/backoff?status.png)](https://godoc.org/github.com/cenkalti/backoff)
[![Build Status](https://travis-ci.org/cenkalti/backoff.png)](https://travis-ci.org/cenkalti/backoff)
This is a Go port of the exponential backoff algorithm from
[google-http-java-client](https://code.google.com/p/google-http-java-client/wiki/ExponentialBackoff).
[Exponential backoff](http://en.wikipedia.org/wiki/Exponential_backoff)
is an algorithm that uses feedback to multiplicatively decrease the rate of some process,
in order to gradually find an acceptable rate.
The retries exponentially increase and stop increasing when a certain threshold is met.
## Install
```bash
go get github.com/cenkalti/backoff
```
## Example
Simple retry helper that uses exponential back-off algorithm:
```go
operation := func() error {
// An operation that might fail
}
err := backoff.Retry(operation, backoff.NewExponentialBackOff())
if err != nil {
// handle error
}
// operation is successfull
```
Ticker example:
```go
operation := func() error {
// An operation that may fail
}
b := backoff.NewExponentialBackOff()
ticker := backoff.NewTicker(b)
var err error
for t = range ticker.C {
if err = operation(); err != nil {
log.Println(err, "will retry...")
continue
}
ticker.Stop()
break
}
if err != nil {
// Operation has failed.
}
// Operation is successfull.
```

/*
ExponentialBackOff is an implementation of BackOff that increases the back off
period for each retry attempt using a randomization function that grows exponentially.
NextBackOff() is calculated using the following formula:
randomized_interval =
retry_interval * (random value in range [1 - randomization_factor, 1 + randomization_factor])
In other words NextBackOff() will range between the randomization factor
percentage below and above the retry interval. For example, using 2 seconds as the base retry
interval and 0.5 as the randomization factor, the actual back off period used in the next retry
attempt will be between 1 and 3 seconds.
Note: max_interval caps the retry_interval and not the randomized_interval.
If the time elapsed since an ExponentialBackOff instance is created goes past the
max_elapsed_time then the method NextBackOff() starts returning backoff.Stop.
The elapsed time can be reset by calling Reset().
Example: The default retry_interval is .5 seconds, default randomization_factor is 0.5, default
multiplier is 1.5 and the default max_interval is 1 minute. For 10 tries the sequence will be
(values in seconds) and assuming we go over the max_elapsed_time on the 10th try:
request# retry_interval randomized_interval
1 0.5 [0.25, 0.75]
2 0.75 [0.375, 1.125]
