logstasher
logstasher is a Martini middleware that prints logstash-compatible JSON to an io.Writer
for each HTTP request.
Here's an example from one of the Go microservices we have at @bikeexchange :
{
"@timestamp":"2014-03-01T19:08:06+11:00","@version":1,"method":"GET",
"path":"/locations/slugs/VIC/Williams-Landing","status":200,"size":238,
"duration":14.059902000000001,"params":{"country":["au"]}
}
Used in conjunction with the rotating file writer it allows for rotatable logs ready to feed directly into logstash with no parsing.
Example
package main
import (
"log"
"github.com/codegangsta/martini"
"github.com/mipearson/logstasher"
"github.com/mipearson/rfw"
)
func main() {
m := martini.Classic()
logstashLogFile, err := rfw.Open("hello.log", 0644)
if err != nil {
log.Fatalln(err)
}
defer logstashLogFile.Close()
m.Use(logstasher.Logger(logstashLogFile))
m.Get("/", func() string {
return "Hello world!"
})
m.Run()
}
## logstash.conf
input {
file {
path => ["hello.log"]
codec => "json"
}
}
