OpenTSDB Output Plugin

This plugin writes to a OpenTSDB instance using the "telnet" mode

Transfer "Protocol" in the telnet mode

The expected input from OpenTSDB is specified in the following way:

put <metric> <timestamp> <value> <tagk1=tagv1[ tagk2=tagv2 ...tagkN=tagvN]>

The telegraf output plugin adds an optional prefix to the metric keys so that a subamount can be selected.

put <[prefix.]metric> <timestamp> <value> <tagk1=tagv1[ tagk2=tagv2 ...tagkN=tagvN]>

The OpenTSDB interface can be simulated with this reader:

// opentsdb_telnet_mode_mock.go 
package main

import (
	"io"
	"log"
	"net"
	"os"
)

func main() {
	l, err := net.Listen("tcp", "localhost:4242")
	if err != nil {
		log.Fatal(err)
	}
	defer l.Close()
	for {
		conn, err := l.Accept()
		if err != nil {
			log.Fatal(err)
		}
		go func(c net.Conn) {
			defer c.Close()
			io.Copy(os.Stdout, c)
		}(conn)
	}
}

Allowed values for metrics

OpenTSDB allows integers and floats as input values
