Metrics are not flushed to graphite

[ChristianKniep]

Hey there, I am using the following docker-compose file to run the stack.

services:
 gostatsd:
  image: atlassianlabs/gostatsd:39.1.12
  command:
   - --config-path
   - /etc/gostatsd/config.toml
   - --log-raw-metric
   - --flush-interval=30s
   - --verbose
  ports:
    - "8125:8125/udp"
    - "8126:8126"
    - "8181:8181"
  volumes:
   - ./config.toml:/etc/gostatsd/config.toml:ro
 graphite:
  image: sitespeedio/graphite
  ports:
    - "8080:80"
    - "8001:8000"
    - "2003:2003"
    - "2004:2004"
    - "7002:7002"
  volumes:
    - ./data/graphite:/opt/graphite/storage/whisper
 grafana:
  image: grafana/grafana
  ports:
    - "3000:3000"
#  volumes:
#    - ./data/grafana:/var/lib/grafana
  environment:
    - GF_SECURITY_ADMIN_PASSWORD=admin

The config is as follows:

server-mode='standalone'
statser-type='null'
flush-interval='1s'
backends=['graphite']
[graphite]
address = "graphite:2003"
dial_timeout = '3s'
write_timeout = '10s'
mode = 'tags'
global_prefix = 'd'
prefix_counter = 'counters'
prefix_timer = 'timers'
prefix_gauge = 'gauges'
prefix_sets = 'sets'

I can send metrics to statsd...

while [ true ];do sleep 2;echo "foo.gauge:${RANDOM}|g"   | nc -u -w0 localhost 8125;done

.. they'll show up in the logs

I even see statsd internal metrics that metrics are received in Graphite.

I am also able to send metrics to graphite from within the gostatsd container.

 docker exec -ti $(docker ps -ql) ash
/ # echo "local.random.diceroll2 4 `date +%s`" |nc graphite 2003

But I can not find any statsd metrics I send to statsd ( the foo.gauge).

Someone has an idea what I miss?
