NOTE: when using image datadog/docker-dd-agent:latest no errors such as the error above

using node.js with library node-statsd

Hi @dror-ventura thanks for the feedback. Can you give us more details about your setup? Maybe how you run the agent container, and a snippet that gives this failure message.

Thanks

from my docker-compose:

dd-agent:
    image: datadog/docker-dd-agent:latest-alpine

    environment:
      - API_KEY=<MY_API_KEY>

    volumes:
       - /var/run/docker.sock:/var/run/docker.sock
       - /proc/mounts:/host/proc/mounts:ro
       - /sys/fs/cgroup:/host/sys/fs/cgroup:ro

I tried it in my staging environment for some time and unfortunately I don't have a specific call stack of my application when the errors occur, I can say that I'm using mostly increment metrics, and error events while using node-statsd library.

i'm running datadog/docker-dd-agent:latest on production along with the same code and configuration and i haven't received such errors

Thanks, and how does the code calling node-statsd look like? I'm trying to understand how your code tries to reach the agent.
