exclude a container check

[xueshanf]

I have a container controlled by a timer unit. It runs every 30 seconds and I want to exclude it from the datadog agent check. The image is tagged as 'example.com/itlab/s3sync:latest'. I tried the following config:

conf.d/docker.yaml
....

include all, except s3sync

  include: []
  exclude:
     - "image:example.com/itlab/s3sync:latest"
     - "example.com/itlab/s3sync:llatest"
     - ".*s3sync*"

...

The exclude does not seem to work. I still see the events for this container that comes and go.
What's the correct format to exclude a container check?

Hi @xueshanf,
Thanks for this report! It's definitively a bug: the filter doesn't apply to events. It only applies to metrics.

Can you check if the Agent reports Docker metrics relative to this container? (you can for example, in the Metric Explorer, look at docker.cpu.user tagged by this container name).

Then I'll open another issue on the Docker Check (https://github.com/DataDog/dd-agent) since it's not related to the container version of the Agent.

Thanks for the screenshot! It's making this easier.
However we are reporting metrics per host / per container. So maybe this specific container wasn't reporting.
Can you display the graph with the option "One graph per" then you pick "name" (or "container_name", depending on your Agent version). Then you will see one graph per container, running on this host.
If the one filtered isn't there, it means that it got properly filtered!

@LotharSee,

Here is a screenshot with cpu per container metrics. It looks like the s3sync container was filtered out, but I am still seeing events data in datadog, they are not filtered out.

I have done some changes, here is the recap of the platform info:

1. CoreOS

2. docker-dd-agent: latest

3. Conf.d:

   # include all, except awscli
   include: []
   exclude:
     - "name:s3sync"
     - "image:.*awscli"
   #

Thanks for this detailed explanation.
This way I was able to open an issue on the Agent project: DataDog/dd-agent#1234

I'll close this one, you can follow this issue and I'll notify you there once it's fixed!
