Agent host is none when running in ECS Fargate #12406

Open eddycharly opened 2 years ago

eddycharly commented 2 years ago

I'm running the DD agent in a task container on ECS Fargate, however the agent shows with host none in the infrastructure list.

Is there a configuration option to get an host for each running agent in my tasks ?

iniinikoski commented 2 years ago

Hmm - is this even possible... As there are no hosts in Fargate...

eddycharly commented 2 years ago

I guess it appears in the list because it sends traces and the host label is not set ?

FWIW, I followed the doc here https://docs.datadoghq.com/fr/integrations/ecs_fargate

I see the same thing. Would be nice if there was a value. Looking at logs you can see that there is no host set.

I'm busy debugging an issue where my Datadog APM on ECS Fargate randomly stopped working with no changes on my side. Only change was the 7.40.0 release, but sadly reverting back to 7.39.x isn't working either.

In my logs I can see Trace agent running on host and it is empty.

Seeing the same issue. The agent logs shows this:
