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
