# Zero Allocation JSON Logger
|
||||
|
||||
[](https://godoc.org/github.com/rs/zerolog) [](https://raw.githubusercontent.com/rs/zerolog/master/LICENSE) [](https://travis-ci.org/rs/zerolog) [](http://gocover.io/github.com/rs/zerolog)
|
||||
|
||||
The zerolog package provides a fast and simple logger dedicated to JSON output.
|
||||
|
||||
Zerolog's API is designed to provide both a great developer experience and stunning [performance](#benchmarks). Its unique chaining API allows zerolog to write JSON (or CBOR) log events by avoiding allocations and reflection.
|
||||
|
||||
Uber's [zap](https://godoc.org/go.uber.org/zap) library pioneered this approach. Zerolog is taking this concept to the next level with a simpler to use API and even better performance.
|
||||
|
||||
To keep the code base and the API simple, zerolog focuses on efficient structured logging only. Pretty logging on the console is made possible using the provided (but inefficient) [`zerolog.ConsoleWriter`](#pretty-logging).
|
||||
|
||||
|
||||
|
||||
## Who uses zerolog
|
||||
|
||||
Find out [who uses zerolog](https://github.com/rs/zerolog/wiki/Who-uses-zerolog) and add your company / project to the list.
|
||||
|
||||
## Features
|
||||
|
||||
* [Blazing fast](#benchmarks)
|
||||
* [Low to zero allocation](#benchmarks)
|
||||
* [Leveled logging](#leveled-logging)
|
||||
* [Sampling](#log-sampling)
|
||||
* [Hooks](#hooks)
|
||||
* [Contextual fields](#contextual-logging)
|
||||
* `context.Context` integration
|
||||
* [Integration with `net/http`](#integration-with-nethttp)
|
||||
* [JSON and CBOR encoding formats](#binary-encoding)
|
||||
* [Pretty logging for development](#pretty-logging)
|
||||
* [Error Logging (with optional Stacktrace)](#error-logging)
|
||||
|
||||
## Installation
|
||||
|
||||
```bash
|
||||
go get -u github.com/rs/zerolog/log
|
||||
```
|
||||
|
||||
## Getting Started
|
||||
|
||||
### Simple Logging Example
|
||||
|
||||
For simple logging, import the global logger package **github.com/rs/zerolog/log**
|
||||
|
||||
```go
|
||||
package main
|
||||
|
||||
import (
|
||||
"github.com/rs/zerolog"
|
||||
"github.com/rs/zerolog/log"
|
||||
)
|
||||
|
||||
func main() {
|
||||
// UNIX Time is faster and smaller than most timestamps
|
||||
zerolog.TimeFieldFormat = zerolog.TimeFormatUnix
|
||||
|
||||
log.Print("hello world")
|
||||
}
|
||||
|
||||
// Output: {"time":1516134303,"level":"debug","message":"hello world"}
|
||||
```
|
||||
> Note: By default log writes to `os.Stderr`
|
||||
> Note: The default log level for `log.Print` is *debug*
|
||||
|
||||
### Contextual Logging
|
||||
|
||||
**zerolog** allows data to be added to log messages in the form of key:value pairs. The data added to the message adds "context" about the log event that can be critical for debugging as well as myriad other purposes. An example of this is below:
|
||||
|
||||
```go
|
||||
package main
|
||||
|
||||
import (
|
||||
"github.com/rs/zerolog"
|
||||
"github.com/rs/zerolog/log"
|
||||
)
|
||||
|
||||
func main() {
|
||||
zerolog.TimeFieldFormat = zerolog.TimeFormatUnix
|
||||
|
||||
log.Debug().
|
||||
Str("Scale", "833 cents").
|
||||
Float64("Interval", 833.09).
|
||||
Msg("Fibonacci is everywhere")
|
||||
|
||||
log.Debug().
|
||||
Str("Name", "Tom").
|
||||
Send()
|
||||
}
|
||||
|
||||
// Output: {"level":"debug","Scale":"833 cents","Interval":833.09,"time":1562212768,"message":"Fibonacci is everywhere"}
|
||||
// Output: {"level":"debug","Name":"Tom","time":1562212768}
|
||||
```
|
||||
|
||||
> You'll note in the above example that when adding contextual fields, the fields are strongly typed. You can find the full list of supported fields [here](#standard-types)
|
||||
|
||||
### Leveled Logging
|
||||
|
||||
#### Simple Leveled Logging Example
|
||||
|
||||
```go
|
||||
package main
|
||||
|
||||
import (
|
||||
"github.com/rs/zerolog"
|
||||
"github.com/rs/zerolog/log"
|
||||
)
|
||||
|
||||
func main() {
|
||||
zerolog.TimeFieldFormat = zerolog.TimeFormatUnix
|
||||
|
||||
log.Info().Msg("hello world")
|
||||
}
|
||||
|
||||
// Output: {"time":1516134303,"level":"info","message":"hello world"}
|
||||
```
|
||||
|
||||
> It is very important to note that when using the **zerolog** chaining API, as shown above (`log.Info().Msg("hello world"`), the chain must have either the `Msg` or `Msgf` method call. If you forget to add either of these, the log will not occur and there is no compile time error to alert you of this.
|
||||
|
||||
**zerolog** allows for logging at the following levels (from highest to lowest):
|
||||
|
||||
* panic (`zerolog.PanicLevel`, 5)
|
||||
* fatal (`zerolog.FatalLevel`, 4)
|
||||
* error (`zerolog.ErrorLevel`, 3)
|
||||
* warn (`zerolog.WarnLevel`, 2)
|
||||
* info (`zerolog.InfoLevel`, 1)
|
||||
* debug (`zerolog.DebugLevel`, 0)
|
||||
* trace (`zerolog.TraceLevel`, -1)
|
||||
|
||||
You can set the Global logging level to any of these options using the `SetGlobalLevel` function in the zerolog package, passing in one of the given constants above, e.g. `zerolog.InfoLevel` would be the "info" level. Whichever level is chosen, all logs with a level greater than or equal to that level will be written. To turn off logging entirely, pass the `zerolog.Disabled` constant.
|
||||
|
||||
#### Setting Global Log Level
|
||||
|
||||
This example uses command-line flags to demonstrate various outputs depending on the chosen log level.
|
||||
|
||||
```go
|
||||
package main
|
||||
|
||||
import (
|
||||
"flag"
|
||||
|
||||
"github.com/rs/zerolog"
|
||||
"github.com/rs/zerolog/log"
|
||||
)
|
||||
|
||||
func main() {
|
||||
zerolog.TimeFieldFormat = zerolog.TimeFormatUnix
|
||||
debug := flag.Bool("debug", false, "sets log level to debug")
|
||||
|
||||
flag.Parse()
|
||||
|
||||
// Default level for this example is info, unless debug flag is present
|
||||
zerolog.SetGlobalLevel(zerolog.InfoLevel)
|
||||
if *debug {
|
||||
zerolog.SetGlobalLevel(zerolog.DebugLevel)
|
||||
}
|
||||
|
||||
log.Debug().Msg("This message appears only when log level set to Debug")
|
||||
log.Info().Msg("This message appears when log level set to Debug or Info")
|
||||
|
||||
if e := log.Debug(); e.Enabled() {
|
||||
// Compute log output only if enabled.
|
||||
value := "bar"
|
||||
e.Str("foo", value).Msg("some debug message")
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
Info Output (no flag)
|
||||
|
||||
```bash
|
||||
$ ./logLevelExample
|
||||
{"time":1516387492,"level":"info","message":"This message appears when log level set to Debug or Info"}
|
||||
```
|
||||
|
||||
Debug Output (debug flag set)
|
||||
|
||||
```bash
|
||||
$ ./logLevelExample -debug
|
||||
{"time":1516387573,"level":"debug","message":"This message appears only when log level set to Debug"}
|
||||
{"time":1516387573,"level":"info","message":"This message appears when log level set to Debug or Info"}
|
||||
{"time":1516387573,"level":"debug","foo":"bar","message":"some debug message"}
|
||||
```
|
||||
|
||||
#### Logging without Level or Message
|
||||
|
||||
You may choose to log without a specific level by using the `Log` method. You may also write without a message by setting an empty string in the `msg string` parameter of the `Msg` method. Both are demonstrated in the example below.
|
||||
|
||||
```go
|
||||
package main
|
||||
|
||||
import (
|
||||
"github.com/rs/zerolog"
|
||||
"github.com/rs/zerolog/log"
|
||||
)
|
||||
|
||||
func main() {
|
||||
zerolog.TimeFieldFormat = zerolog.TimeFormatUnix
|
||||
|
||||
log.Log().
|
||||
Str("foo", "bar").
|
||||
Msg("")
|
||||
}
|
||||
|
||||
// Output: {"time":1494567715,"foo":"bar"}
|
||||
```
|
||||
|
||||
### Error Logging
|
||||
|
||||
You can log errors using the `Err` method
|
||||
|
||||
```go
|
||||
package main
|
||||
|
||||
import (
|
||||
"errors"
|
||||
|
||||
"github.com/rs/zerolog"
|
||||
"github.com/rs/zerolog/log"
|
||||
)
|
||||
|
||||
func main() {
|
||||
zerolog.TimeFieldFormat = zerolog.TimeFormatUnix
|
||||
|
||||
err := errors.New("seems we have an error here")
|
||||
log.Error().Err(err).Msg("")
|
||||
}
|
||||
|
||||
// Output: {"level":"error","error":"seems we have an error here","time":1609085256}
|
||||
```
|
||||
|
||||
> The default field name for errors is `error`, you can change this by setting `zerolog.ErrorFieldName` to meet your needs.
|
||||
|
||||
#### Error Logging with Stacktrace
|
||||
|
||||
Using `github.com/pkg/errors`, you can add a formatted stacktrace to your errors.
|
||||
|
||||
```go
|
||||
package main
|
||||
|
||||
import (
|
||||
"github.com/pkg/errors"
|
||||
"github.com/rs/zerolog/pkgerrors"
|
||||
|
||||
"github.com/rs/zerolog"
|
||||
"github.com/rs/zerolog/log"
|
||||
)
|
||||
|
||||
func main() {
|
||||
zerolog.TimeFieldFormat = zerolog.TimeFormatUnix
|
||||
zerolog.ErrorStackMarshaler = pkgerrors.MarshalStack
|
||||
|
||||
err := outer()
|
||||
log.Error().Stack().Err(err).Msg("")
|
||||
}
|
||||
|
||||
func inner() error {
|
||||
return errors.New("seems we have an error here")
|
||||
}
|
||||
|
||||
func middle() error {
|
||||
err := inner()
|
||||
if err != nil {
|
||||
return err
|
||||
}
|
||||
return nil
|
||||
}
|
||||
|
||||
func outer() error {
|
||||
err := middle()
|
||||
if err != nil {
|
||||
return err
|
||||
}
|
||||
return nil
|
||||
}
|
||||
|
||||
// Output: {"level":"error","stack":[{"func":"inner","line":"20","source":"errors.go"},{"func":"middle","line":"24","source":"errors.go"},{"func":"outer","line":"32","source":"errors.go"},{"func":"main","line":"15","source":"errors.go"},{"func":"main","line":"204","source":"proc.go"},{"func":"goexit","line":"1374","source":"asm_amd64.s"}],"error":"seems we have an error here","time":1609086683}
|
||||
```
|
||||
|
||||
> zerolog.ErrorStackMarshaler must be set in order for the stack to output anything.
|
||||
|
||||
#### Logging Fatal Messages
|
||||
|
||||
```go
|
||||
package main
|
||||
|
||||
import (
|
||||
"errors"
|
||||
|
||||
"github.com/rs/zerolog"
|
||||
"github.com/rs/zerolog/log"
|
||||
)
|
||||
|
||||
func main() {
|
||||
err := errors.New("A repo man spends his life getting into tense situations")
|
||||
service := "myservice"
|
||||
|
||||
zerolog.TimeFieldFormat = zerolog.TimeFormatUnix
|
||||
|
||||
log.Fatal().
|
||||
Err(err).
|
||||
Str("service", service).
|
||||
Msgf("Cannot start %s", service)
|
||||
}
|
||||
|
||||
// Output: {"time":1516133263,"level":"fatal","error":"A repo man spends his life getting into tense situations","service":"myservice","message":"Cannot start myservice"}
|
||||
// exit status 1
|
||||
```
|
||||
|
||||
> NOTE: Using `Msgf` generates one allocation even when the logger is disabled.
|
||||
|
||||
|
||||
### Create logger instance to manage different outputs
|
||||
|
||||
```go
|
||||
logger := zerolog.New(os.Stderr).With().Timestamp().Logger()
|
||||
|
||||
logger.Info().Str("foo", "bar").Msg("hello world")
|
||||
|
||||
// Output: {"level":"info","time":1494567715,"message":"hello world","foo":"bar"}
|
||||
```
|
||||
|
||||
### Sub-loggers let you chain loggers with additional context
|
||||
|
||||
```go
|
||||
sublogger := log.With().
|
||||
Str("component", "foo").
|
||||
Logger()
|
||||
sublogger.Info().Msg("hello world")
|
||||
|
||||
// Output: {"level":"info","time":1494567715,"message":"hello world","component":"foo"}
|
||||
```
|
||||
|
||||
### Pretty logging
|
||||
|
||||
To log a human-friendly, colorized output, use `zerolog.ConsoleWriter`:
|
||||
|
||||
```go
|
||||
log.Logger = log.Output(zerolog.ConsoleWriter{Out: os.Stderr})
|
||||
|
||||
log.Info().Str("foo", "bar").Msg("Hello world")
|
||||
|
||||
// Output: 3:04PM INF Hello World foo=bar
|
||||
```
|
||||
|
||||
To customize the configuration and formatting:
|
||||
|
||||
```go
|
||||
output := zerolog.ConsoleWriter{Out: os.Stdout, TimeFormat: time.RFC3339}
|
||||
output.FormatLevel = func(i interface{}) string {
|
||||
return strings.ToUpper(fmt.Sprintf("| %-6s|", i))
|
||||
}
|
||||
output.FormatMessage = func(i interface{}) string {
|
||||
return fmt.Sprintf("***%s****", i)
|
||||
}
|
||||
output.FormatFieldName = func(i interface{}) string {
|
||||
return fmt.Sprintf("%s:", i)
|
||||
}
|
||||
output.FormatFieldValue = func(i interface{}) string {
|
||||
return strings.ToUpper(fmt.Sprintf("%s", i))
|
||||
}
|
||||
|
||||
log := zerolog.New(output).With().Timestamp().Logger()
|
||||
|
||||
log.Info().Str("foo", "bar").Msg("Hello World")
|
||||
|
||||
// Output: 2006-01-02T15:04:05Z07:00 | INFO | ***Hello World**** foo:BAR
|
||||
```
|
||||
|
||||
### Sub dictionary
|
||||
|
||||
```go
|
||||
log.Info().
|
||||
Str("foo", "bar").
|
||||
Dict("dict", zerolog.Dict().
|
||||
Str("bar", "baz").
|
||||
Int("n", 1),
|
||||
).Msg("hello world")
|
||||
|
||||
// Output: {"level":"info","time":1494567715,"foo":"bar","dict":{"bar":"baz","n":1},"message":"hello world"}
|
||||
```
|
||||
|
||||
### Customize automatic field names
|
||||
|
||||
```go
|
||||
zerolog.TimestampFieldName = "t"
|
||||
zerolog.LevelFieldName = "l"
|
||||
zerolog.MessageFieldName = "m"
|
||||
|
||||
log.Info().Msg("hello world")
|
||||
|
||||
// Output: {"l":"info","t":1494567715,"m":"hello world"}
|
||||
```
|
||||
|
||||
### Add contextual fields to the global logger
|
||||
|
||||
```go
|
||||
log.Logger = log.With().Str("foo", "bar").Logger()
|
||||
```
|
||||
|
||||
### Add file and line number to log
|
||||
|
||||
```go
|
||||
log.Logger = log.With().Caller().Logger()
|
||||
log.Info().Msg("hello world")
|
||||
|
||||
// Output: {"level": "info", "message": "hello world", "caller": "/go/src/your_project/some_file:21"}
|
||||
```
|
||||
|
||||
|
||||
### Thread-safe, lock-free, non-blocking writer
|
||||
|
||||
If your writer might be slow or not thread-safe and you need your log producers to never get slowed down by a slow writer, you can use a `diode.Writer` as follow:
|
||||
|
||||
```go
|
||||
wr := diode.NewWriter(os.Stdout, 1000, 10*time.Millisecond, func(missed int) {
|
||||
fmt.Printf("Logger Dropped %d messages", missed)
|
||||
})
|
||||
log := zerolog.New(wr)
|
||||
log.Print("test")
|
||||
```
|
||||
|
||||
You will need to install `code.cloudfoundry.org/go-diodes` to use this feature.
|
||||
|
||||
### Log Sampling
|
||||
|
||||
```go
|
||||
sampled := log.Sample(&zerolog.BasicSampler{N: 10})
|
||||
sampled.Info().Msg("will be logged every 10 messages")
|
||||
|
||||
// Output: {"time":1494567715,"level":"info","message":"will be logged every 10 messages"}
|
||||
```
|
||||
|
||||
More advanced sampling:
|
||||
|
||||
```go
|
||||
// Will let 5 debug messages per period of 1 second.
|
||||
// Over 5 debug message, 1 every 100 debug messages are logged.
|
||||
// Other levels are not sampled.
|
||||
sampled := log.Sample(zerolog.LevelSampler{
|
||||
DebugSampler: &zerolog.BurstSampler{
|
||||
Burst: 5,
|
||||
Period: 1*time.Second,
|
||||
NextSampler: &zerolog.BasicSampler{N: 100},
|
||||
},
|
||||
})
|
||||
sampled.Debug().Msg("hello world")
|
||||
|
||||
// Output: {"time":1494567715,"level":"debug","message":"hello world"}
|
||||
```
|
||||
|
||||
### Hooks
|
||||
|
||||
```go
|
||||
type SeverityHook struct{}
|
||||
|
||||
func (h SeverityHook) Run(e *zerolog.Event, level zerolog.Level, msg string) {
|
||||
if level != zerolog.NoLevel {
|
||||
e.Str("severity", level.String())
|
||||
}
|
||||
}
|
||||
|
||||
hooked := log.Hook(SeverityHook{})
|
||||
hooked.Warn().Msg("")
|
||||
|
||||
// Output: {"level":"warn","severity":"warn"}
|
||||
```
|
||||
|
||||
### Pass a sub-logger by context
|
||||
|
||||
```go
|
||||
ctx := log.With().Str("component", "module").Logger().WithContext(ctx)
|
||||
|
||||
log.Ctx(ctx).Info().Msg("hello world")
|
||||
|
||||
// Output: {"component":"module","level":"info","message":"hello world"}
|
||||
```
|
||||
|
||||
### Set as standard logger output
|
||||
|
||||
```go
|
||||
log := zerolog.New(os.Stdout).With().
|
||||
Str("foo", "bar").
|
||||
Logger()
|
||||
|
||||
stdlog.SetFlags(0)
|
||||
stdlog.SetOutput(log)
|
||||
|
||||
stdlog.Print("hello world")
|
||||
|
||||
// Output: {"foo":"bar","message":"hello world"}
|
||||
```
|
||||
|
||||
### Integration with `net/http`
|
||||
|
||||
The `github.com/rs/zerolog/hlog` package provides some helpers to integrate zerolog with `http.Handler`.
|
||||
|
||||
In this example we use [alice](https://github.com/justinas/alice) to install logger for better readability.
|
||||
|
||||
```go
|
||||
log := zerolog.New(os.Stdout).With().
|
||||
Timestamp().
|
||||
Str("role", "my-service").
|
||||
Str("host", host).
|
||||
Logger()
|
||||
|
||||
c := alice.New()
|
||||
|
||||
// Install the logger handler with default output on the console
|
||||
c = c.Append(hlog.NewHandler(log))
|
||||
|
||||
// Install some provided extra handler to set some request's context fields.
|
||||
// Thanks to that handler, all our logs will come with some prepopulated fields.
|
||||
c = c.Append(hlog.AccessHandler(func(r *http.Request, status, size int, duration time.Duration) {
|
||||
hlog.FromRequest(r).Info().
|
||||
Str("method", r.Method).
|
||||
Stringer("url", r.URL).
|
||||
Int("status", status).
|
||||
Int("size", size).
|
||||
Dur("duration", duration).
|
||||
Msg("")
|
||||
}))
|
||||
c = c.Append(hlog.RemoteAddrHandler("ip"))
|
||||
c = c.Append(hlog.UserAgentHandler("user_agent"))
|
||||
c = c.Append(hlog.RefererHandler("referer"))
|
||||
c = c.Append(hlog.RequestIDHandler("req_id", "Request-Id"))
|
||||
|
||||
// Here is your final handler
|
||||
h := c.Then(http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
|
||||
// Get the logger from the request's context. You can safely assume it
|
||||
// will be always there: if the handler is removed, hlog.FromRequest
|
||||
// will return a no-op logger.
|
||||
hlog.FromRequest(r).Info().
|
||||
Str("user", "current user").
|
||||
Str("status", "ok").
|
||||
Msg("Something happened")
|
||||
|
||||
// Output: {"level":"info","time":"2001-02-03T04:05:06Z","role":"my-service","host":"local-hostname","req_id":"b4g0l5t6tfid6dtrapu0","user":"current user","status":"ok","message":"Something happened"}
|
||||
}))
|
||||
http.Handle("/", h)
|
||||
|
||||
if err := http.ListenAndServe(":8080", nil); err != nil {
|
||||
log.Fatal().Err(err).Msg("Startup failed")
|
||||
}
|
||||
```
|
||||
|
||||
## Multiple Log Output
|
||||
`zerolog.MultiLevelWriter` may be used to send the log message to multiple outputs.
|
||||
In this example, we send the log message to both `os.Stdout` and the in-built ConsoleWriter.
|
||||
```go
|
||||
func main() {
|
||||
consoleWriter := zerolog.ConsoleWriter{Out: os.Stdout}
|
||||
|
||||
multi := zerolog.MultiLevelWriter(consoleWriter, os.Stdout)
|
||||
|
||||
logger := zerolog.New(multi).With().Timestamp().Logger()
|
||||
|
||||
logger.Info().Msg("Hello World!")
|
||||
}
|
||||
|
||||
// Output (Line 1: Console; Line 2: Stdout)
|
||||
// 12:36PM INF Hello World!
|
||||
// {"level":"info","time":"2019-11-07T12:36:38+03:00","message":"Hello World!"}
|
||||
```
|
||||
|
||||
## Global Settings
|
||||
|
||||
Some settings can be changed and will by applied to all loggers:
|
||||
|
||||
* `log.Logger`: You can set this value to customize the global logger (the one used by package level methods).
|
||||
* `zerolog.SetGlobalLevel`: Can raise the minimum level of all loggers. Call this with `zerolog.Disabled` to disable logging altogether (quiet mode).
|
||||
* `zerolog.DisableSampling`: If argument is `true`, all sampled loggers will stop sampling and issue 100% of their log events.
|
||||
* `zerolog.TimestampFieldName`: Can be set to customize `Timestamp` field name.
|
||||
* `zerolog.LevelFieldName`: Can be set to customize level field name.
|
||||
* `zerolog.MessageFieldName`: Can be set to customize message field name.
|
||||
* `zerolog.ErrorFieldName`: Can be set to customize `Err` field name.
|
||||
* `zerolog.TimeFieldFormat`: Can be set to customize `Time` field value formatting. If set with `zerolog.TimeFormatUnix`, `zerolog.TimeFormatUnixMs` or `zerolog.TimeFormatUnixMicro`, times are formated as UNIX timestamp.
|
||||
* `zerolog.DurationFieldUnit`: Can be set to customize the unit for time.Duration type fields added by `Dur` (default: `time.Millisecond`).
|
||||
* `zerolog.DurationFieldInteger`: If set to `true`, `Dur` fields are formatted as integers instead of floats (default: `false`).
|
||||
* `zerolog.ErrorHandler`: Called whenever zerolog fails to write an event on its output. If not set, an error is printed on the stderr. This handler must be thread safe and non-blocking.
|
||||
|
||||
## Field Types
|
||||
|
||||
### Standard Types
|
||||
|
||||
* `Str`
|
||||
* `Bool`
|
||||
* `Int`, `Int8`, `Int16`, `Int32`, `Int64`
|
||||
* `Uint`, `Uint8`, `Uint16`, `Uint32`, `Uint64`
|
||||
* `Float32`, `Float64`
|
||||
|
||||
### Advanced Fields
|
||||
|
||||
* `Err`: Takes an `error` and renders it as a string using the `zerolog.ErrorFieldName` field name.
|
||||
* `Func`: Run a `func` only if the level is enabled.
|
||||
* `Timestamp`: Inserts a timestamp field with `zerolog.TimestampFieldName` field name, formatted using `zerolog.TimeFieldFormat`.
|
||||
* `Time`: Adds a field with time formatted with `zerolog.TimeFieldFormat`.
|
||||
* `Dur`: Adds a field with `time.Duration`.
|
||||
* `Dict`: Adds a sub-key/value as a field of the event.
|
||||
* `RawJSON`: Adds a field with an already encoded JSON (`[]byte`)
|
||||
* `Hex`: Adds a field with value formatted as a hexadecimal string (`[]byte`)
|
||||
* `Interface`: Uses reflection to marshal the type.
|
||||
|
||||
Most fields are also available in the slice format (`Strs` for `[]string`, `Errs` for `[]error` etc.)
|
||||
|
||||
## Binary Encoding
|
||||
|
||||
In addition to the default JSON encoding, `zerolog` can produce binary logs using [CBOR](http://cbor.io) encoding. The choice of encoding can be decided at compile time using the build tag `binary_log` as follows:
|
||||
|
||||
```bash
|
||||
go build -tags binary_log .
|
||||
```
|
||||
|
||||
To Decode binary encoded log files you can use any CBOR decoder. One has been tested to work
|
||||
with zerolog library is [CSD](https://github.com/toravir/csd/).

|
||||
|
||||
## Caveats
|
||||
|
||||
Note that zerolog does no de-duplication of fields. Using the same key multiple times creates multiple keys in final JSON:
|
||||
|
||||
```go
|
||||
logger := zerolog.New(os.Stderr).With().Timestamp().Logger()
|
||||
logger.Info().
|
||||
Timestamp().
|
||||
Msg("dup")
|
||||
// Output: {"level":"info","time":1494567715,"time":1494567715,"message":"dup"}
|
||||
```
|
||||
|
||||
In this case, many consumers will take the last value, but this is not guaranteed; check yours if in doubt.

## Reference:
|
||||
CBOR Encoding is described in [RFC7049](https://tools.ietf.org/html/rfc7049)
|
||||
|
||||
## Comparison of JSON vs CBOR
|
||||
|
||||
Two main areas of reduction are:
|
||||
|
||||
1. CPU usage to write a log msg
|
||||
2. Size (in bytes) of log messages.
|
||||
|
||||
|
||||
CPU Usage savings are below:
|
||||
```

||||

|
||||
```
|
||||
|
||||
Log message size savings is greatly dependent on the number and type of fields in the log message.
|
||||
Assuming this log message (with an Integer, timestamp and string, in addition to level).
|
||||
|
||||
`{"level":"error","Fault":41650,"time":"2018-04-01T15:18:19-07:00","message":"Some Message"}`
|
||||
|
||||
Two measurements were done for the log file sizes - one without any compression, second
|
||||
using [compress/zlib](https://golang.org/pkg/compress/zlib/).
|
||||
|
||||
Results for 10,000 log messages:
|
||||
|
||||
| Log Format | Plain File Size (in KB) | Compressed File Size (in KB) |
|
||||
| :--- | :---: | :---: |
|
||||
| JSON | 920 | 28 |
|
||||
| CBOR | 550 | 28 |
|
||||
|
||||
The example used to calculate the above data is available in [Examples](examples).

// Package zerolog provides a lightweight logging library dedicated to JSON logging.
|

|

//
|

// import "github.com/rs/zerolog/log"
|
||||
//
|
||||
// log.Info().Msg("hello world")
|

// // Output: {"time":1494567715,"level":"info","message":"hello world"}
|

//
|
||||
// NOTE: To import the global logger, import the "log" subpackage "github.com/rs/zerolog/log".
|
||||
//
|
||||
// Fields can be added to log messages:
|
||||
//
|
||||
// log.Info().Str("foo", "bar").Msg("hello world")
|
||||
// // Output: {"time":1494567715,"level":"info","message":"hello world","foo":"bar"}
|
||||
//
|
||||
// Create logger instance to manage different outputs:
|
||||
//
|
||||
// logger := zerolog.New(os.Stderr).With().Timestamp().Logger()
|
||||
// logger.Info().
|
||||
// Str("foo", "bar").
|

// Msg("hello world")
|
||||
// // Output: {"time":1494567715,"level":"info","message":"hello world","foo":"bar"}
|
||||
//
|
||||
// Sub-loggers let you chain loggers with additional context:
|
||||
//
|
||||
// sublogger := log.With().Str("component": "foo").Logger()
|
||||
// sublogger.Info().Msg("hello world")

|
