# 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 |
