Logrus Mate
Logrus mate is a tool for Logrus, it will help you to initial logger by config, including Formatter
, Hook
,Level
and Output
.
If you more prefer old version, you could checkout tag v1.0.0
Example
Example 1:
Hijack logrus.StandardLogger()
package main
import (
"github.com/sirupsen/logrus"
"github.com/gogap/logrus_mate"
)
func main() {
logrus_mate.Hijack(
logrus.StandardLogger(),
logrus_mate.ConfigString(
`{formatter.name = "json"}`,
),
)
logrus.WithField("Field", "A").Debugln("Hello JSON")
}
Example 2:
Create new logger from mate:
package main
import (
"github.com/gogap/logrus_mate"
)
func main() {
mate, _ := logrus_mate.NewLogrusMate(
logrus_mate.ConfigString(
`{ mike {formatter.name = "json"} }`,
),
)
mikeLoger := mate.Logger("mike")
mikeLoger.Errorln("Hello Error Level from Mike and my formatter is json")
}
Example 3:
Hi jack logger by mate
package main
import (
"github.com/sirupsen/logrus"
"github.com/gogap/logrus_mate"
)
func main() {
mate, _ := logrus_mate.NewLogrusMate(
logrus_mate.ConfigString(
`{ mike {formatter.name = "json"} }`,
),
)
mate.Hijack(
logrus.StandardLogger(),
"mike",
)
logrus.Println("hello std logger is hijack by mike")
}
Example 4:
Fallback the ConfigString
package main
import (
"github.com/sirupsen/logrus"
"github.com/gogap/logrus_mate"
)
func main() {
mate, _ := logrus_mate.NewLogrusMate(
logrus_mate.ConfigString(
`{ mike {formatter.name = "json"} }`,
),
logrus_mate.ConfigFile(
"mate.conf", // { mike {formatter.name = "text"} }
),
)
mate.Hijack(
logrus.StandardLogger(),
"mike",
)
logrus.Println("hello std logger is hijack by mike")
}
the json
formatter is used
Example 5:
Fallback config while hijack
package main
import (
"github.com/sirupsen/logrus"
"github.com/gogap/logrus_mate"
)
func main() {
mate, _ := logrus_mate.NewLogrusMate(
logrus_mate.ConfigFile(
"mate.conf", // { mike {formatter.name = "text"} }
),
)
mate.Hijack(logrus.StandardLogger(),
"mike",
logrus_mate.ConfigString(
`{formatter.name = "json"}`,
),
)
logrus.Errorln("hello std logger is hijack by mike")
}
the json
formatter is used
currently we are using https://github.com/go-akka/configuration for logger config, it will more powerful config format for human read, you also could set your own config provider
Hooks
Hook | Options |
---|---|
Airbrake | project-id api-key env |
Syslog | network address priority tag |
BugSnag | api-key |
Slackrus | url levels channel emoji username |
Graylog | address facility extra |
app-name host port from to username password |
|
File | filename max-lines max-size daily max-days rotate level |
BearyChat | url levels channel user markdown async |
LFSHook | path-map { error = "logs/error.log" ... } |
When we need use above hooks, we need import these package as follow:
import _ "github.com/gogap/logrus_mate/hooks/syslog"
import _ "github.com/gogap/logrus_mate/hooks/mail"
If you want write your own hook, you just need todo as follow:
package myhook
import (
"github.com/gogap/logrus_mate"
)
type MyHookConfig struct {
Address string
}
func init() {
logrus_mate.RegisterHook("myhook", NewMyHook)
}
func NewMyHook(config logrus_mate.Configuration) (hook logrus.Hook, err error) {
conf := MyHookConfig{}
if config!=nil {
conf.Address = config.GetString("address")
}
// write your hook logic code here
return
}
Formatters
internal formatters:
Formatter | Options | Output Example |
---|---|---|
null | ||
text | force-colors disable-colors disable-timestamp full-timestamp timestamp-format disable-sorting |
DEBU[0000] Hello Default Logrus Mate |
json | timestamp-format |
{"level":"info","msg":"Hello, I am A Logger from jack","time":"2015-10-18T21:24:19+08:00"} |
3rd formatters:
Formatter | Output Example |
---|---|
logstash [Removed] |
When we need use 3rd formatter, we need import these package as follow:
import _ "github.com/gogap/logrus_mate/formatters/xxx"
If you want write your own formatter, you just need todo as follow:
package myformatter
import (
"github.com/gogap/logrus_mate"
)
type MyFormatterConfig struct {
Address string `json:"address"`
}
func init() {
logrus_mate.RegisterFormatter("myformatter", NewMyFormatter)
}
func NewMyFormatter(config logrus_mate.Configuration) (formatter logrus.Formatter, err error) {
conf := MyFormatterConfig{}
if config!=nil {
conf.Address=config.GetString("address")
}
// write your formatter logic code here
return
}
Writers
internal writers (output):
- stdout
- stderr
- null
3rd writers:
Writer | Description |
---|---|
redisio | just for demo, it will output into redis, the key type is list |
rotatelogs | write log to file , configs: clock location link-name rotation-time max-age |
When we need use 3rd writer, we need import these package as follow:
import _ "github.com/gogap/logrus_mate/writers/redisio"
If you want write your own writer, you just need todo as follow:
package mywriter
import (
"io"
"github.com/gogap/logrus_mate"
)
type MyWriterConfig struct {
Address string `json:"address"`
}
func init() {
logrus_mate.RegisterWriter("mywriter", NewMyWriter)
}
func NewMyWriter(config logrus_mate.Configuration) (writer io.Writer, err error) {
conf := MyWriterConfig{}
if config!=nil {
conf.Address=config.GetString("address")
}
// write your writer logic code here
return
}
Config Provider
The default config provider is HOCON
, you could use your own config provider, just implement the following interface{}
type ConfigurationProvider interface {
LoadConfig(filename string) Configuration
ParseString(cfgStr string) Configuration
}
type Configuration interface {
GetBoolean(path string, defaultVal ...bool) bool
GetByteSize(path string) *big.Int
GetInt32(path string, defaultVal ...int32) int32
GetInt64(path string, defaultVal ...int64) int64
GetString(path string, defaultVal ...string) string
GetFloat32(path string, defaultVal ...float32) float32
GetFloat64(path string, defaultVal ...float64) float64
GetTimeDuration(path string, defaultVal ...time.Duration) time.Duration
GetTimeDurationInfiniteNotAllowed(path string, defaultVal ...time.Duration) time.Duration
GetBooleanList(path string) []bool
GetFloat32List(path string) []float32
GetFloat64List(path string) []float64
GetInt32List(path string) []int32
GetInt64List(path string) []int64
GetByteList(path string) []byte
GetStringList(path string) []string
GetConfig(path string) Configuration
WithFallback(fallback Configuration)
HasPath(path string) bool
Keys() []string
}
set your own config provider
package main
import (
"github.com/gogap/config"
"github.com/gogap/logrus_mate"
"github.com/sirupsen/logrus"
)
func main() {
mate, _ := logrus_mate.NewLogrusMate(
logrus_mate.ConfigString(
`{ mike {formatter.name = "json"} }`,
),
logrus_mate.ConfigFile(
"mate.conf", // { mike {formatter.name = "text"} }
),
logrus_mate.ConfigProvider(
&config.HOCONConfigProvider{}, // this is defualt provider if you did not configurate
),
)
mate.Hijack(
logrus.StandardLogger(),
"mike",
)
logrus.Println("hello std logger is hijack by mike")
}
