Hi, I have an on-premise docker swarm cluster monitored by Dynatrace. I need to gather network metrics from the containers. I know nettracer metrics should be available if we have this option enabled (host level):

But they are not. What do I do wrong? (agent has a proper version)

Yes, it might be the reason. Thank you 😞

Hi,

You are welcome. Maybe that is reason. Anyway, if you are using kernel 4.15 or higher, I would try to restart OneAgent or host or both. Just in case.

Best regards

Hi,

I also have this problem, but in this case the server meets the requirements:
