GO: GELF implements Because of performance, I recommender to build your own TCP or UDP connection to send GELF data:

Quick use

import "github.com/duythinht/gelf"

Create message JSON

func main() {
  message := gelf.Create("Short message content")
              .SetTimestamp(time.Now().Unix())
              .SetFullMessage("This is full message")
              .SetLevel(3)
              .SetHost("chat Server")
              .ToJSON()
}

Zip message

import "github.com/duythinht/gelf/chunk"

func main() {
  // message := ... # JSON message
  buffer := chunk.ZipMessage(message)
}

Chunking message

import "github.com/duythinht/gelf/chunk"

func main() {
  // ZippedMessage := ... # type []byte
  if len(ZippedMessage) > MaxChunkSize) {
    buffers := chunk.GetGelfChunks(ZippedMessage, MaxChunkSize)
  }
}

BTW, I offer a UDP clients pool to send message to graylog (workers by goroutine):

import "github.com/duythinht/gelf/client"

c := client.New(client.Config{
  GraylogHost: "10.60.6.48",
  GraylogPort: 13000,
})

message := gelf.Create("...").ToJSON()

c.Send(message)
