Listening on ip 0.0.0.0

[guyisra]

Currently when using the role, (and then using netstat -uln) it seems that 127.0.0.1 is listening to 8125

is there a configuration to change it so the agent will listen on 0.0.0.0 instead?

Hi @guyisra,

The port 8125 is used by DogStatsD to receive custom metrics from external sources: https://docs.datadoghq.com/developers/dogstatsd/

Typically DogStatsD receives metrics from other local software. If you want to send them from other box beware that it uses UDP and this might increase your packet drop at high throughput.
If you install the agent on the same box as the software sending DogStatsD metrics, you can also use a Unix socket with the agent version 6.

To bind 8125 on all interfaces (ie: 0.0.0.0) you can use the non_local_traffic option in agent5 and dogstatsd_non_local_traffic with agent6

example of playbook:

- hosts: servers
  roles:
    - { role: Datadog.datadog, become: yes } 
  vars:
    datadog_api_key: "123456"
    datadog_config:
      tags: "mytag0, mytag1"
      log_level: INFO
      non_local_traffic: true           # agent version 5
      dogstatsd_non_local_traffic: true # agent version 6

If you want to bind a specific interface (for example a non-loopback interface), you can use instead the bind_host option:

example of playbook:

- hosts: servers
  roles:
    - { role: Datadog.datadog, become: yes } 
  vars:
    datadog_api_key: "123456"
    datadog_config:
      tags: "mytag0, mytag1"
      log_level: INFO
      bind_host: 0.0.0.0 # agent version 5 and 6

Hope this answer your question.
