DogStatsd client stops sending metrics after Datadog agent restarts

[fhervieux]

DogStatsd client version: 5.0.2
Datadog agent version: 7.21.1
Datadog helm chart version: 2.4.14

We are encountering an issue with a Kubernetes setup. Datadog agent is deployed as a Helm chart, containers using the Dogstatsd client are based on the mcr.microsoft.com/dotnet/core/aspnet:3.1 image. The containers are sending gauge metrics using the Dogstatsd client. Every time the agent restarts, metrics stop being sent. A restart of the client container is needed. No error or exception seem to indicate any problem.

This seems to be related to the PR #125 but we are using the version 5.0.2 so it could also be unrelated.

If you need more information I can get it. Thanks!

Hi @fhervieux ,

Sorry for my late answer.
This issue was reported to our support team and the solution is to use Unix Domain Socket instead of UDP. See Unix domain socket support to enable Unix domain socket.

Using Unix Domain Socket seems to fix the problem. It does not occur anymore. Thank you!

Closed as the issue is fixed.
