Log Stash

Push json formatted log to local file system

Usage

1. go get github.com/vonlippmann/logstash
2. import "github.com/vonlippmann/logstash" in your code
3. make a new instance of Logger:

logger := NewLogStash(&Config{
        LogPath:     "<your specified path>",
        LogKeepDays: 0,
        FileName:    "<your specified file name>",
        CleanLog:    false,
})

4. then you can use logger in anywhere you need to sink log to the specified path:

logger.Sink(Massage{
    "auth": "pep-pig",
    "age":  "18",
    })

Hooks

• you can use hook to postprocess the massage you sinked, such as add some other fields. You can do this simply by register a hook function:

logger.RegisterHook(func(msg Massage)(err error){
    mas["email"]="###@example.com"
    return
})

Example

package main

var logger *Logger

func main(){
    for{
         logger.Sink(Massage{
            "auth": "pep-pig",
            "age":  "18",
        })
    }
}

func addField(massage Massage) (err error) {
    massage["email"] = "###@example.com"
    return
}

func init() {
    logger = NewLogStash(&Config{
        LogPath:     "/var/log/logstash",
        LogKeepDays: 0,
        FileName:    "elk",
        CleanLog:    false,
    })
    logger.RegisterHook(addField)
}
