telegraf problem

[metal3d]

Hi,
First: thanks for that nice package !

I wanted to try telegraf and that's what I've got:

./telegraf -config telegraf.conf 
2017-10-06T18:14:38Z I! Starting Telegraf v1.5.0~59bb31e7
2017-10-06T18:14:38Z I! Loaded outputs: influxdb
2017-10-06T18:14:38Z I! Loaded inputs: inputs.influxdb
2017-10-06T18:14:38Z I! Tags enabled: host=iidor.dhcp.lyon.intranet
2017-10-06T18:14:38Z I! Agent Config: Interval:10s, Quiet:false, Hostname:"iidor.dhcp.lyon.intranet", Flush Interval:10s 
2017-10-06T18:14:40Z E! Error in plugin [inputs.influxdb]: [url=http://127.0.0.1:9090/debug/vars]: invalid character '<' looking for beginning of value

And yes, http://127.0.0.1:9090/debug/vars returns a 404 while graph are correctly displayed in grafana at http://127.0.0.1:9090

This is the config I've got:

# Global tags can be specified here in key="value" format.
[global_tags]
  # dc = "us-east-1" # will tag all metrics with dc=us-east-1
  # rack = "1a"
  ## Environment variables can be used as tags, and throughout the config file
  # user = "$USER"


# Configuration for telegraf agent
[agent]
  interval = "10s"
  round_interval = true

  metric_batch_size = 1000

  metric_buffer_limit = 10000

  collection_jitter = "0s"

  flush_interval = "10s"
  flush_jitter = "0s"

  precision = ""

  debug = false
  quiet = false
  logfile = ""

  hostname = ""
  omit_hostname = false

[[inputs.influxdb]]
  urls = ["http://127.0.0.1:9090/debug/vars"]

[[outputs.influxdb]]
  urls = ["http://127.0.0.1:8086"] # required
  database = "stats" # required
  timeout = "5s"

My package includes everything at startup:

package ogle

import (
	"fmt"
	"time"

	metrics "github.com/tevjef/go-runtime-metrics"
	_ "github.com/tevjef/go-runtime-metrics/expvar"
)

func init() {
	metrics.DefaultConfig.CollectionInterval = time.Second
	if err := metrics.RunCollector(metrics.DefaultConfig); err != nil {
		fmt.Println(err)
	}
}

One more time, graphs are ok.

Can you tell me what I'm doing wrong ?

[metal3d]

I forget to say that I'm starting grafana and influxdb with a docker-compose file:

version: "2"
services:
  grafana:
    image: grafana/grafana:4.1.0
    ports:
      - 9090:3000
  influxdb:
    image: influxdb
    ports:
      - 8086:8086

[metal3d]

Ok, I just understand that the input in example is wrong. 6060 (or 9090 in my own install) should be 8086, that is the port for influxdb and not graphana. I didn't checked (because the lack of knowledge about telegraf).

Now... the only problem is that I really dont understand what does telegraf and how to configure grafana to use it :)

Could you please make precision in you example ?

Thanks a lot
