I have a server running several docker containers. I wanted to know about network usage of individual and some specific docker containers. I wad able to get entire traffic using below api
http://<server-ip>:19999/api/v1/data?chart=net.docker0&after=-60&before=0&points=1&group=median>ime=0&format=json&options=seconds&options=jsonwrap
I goes through documentations and didn't find anything helpfull.
If you know the specific container name then you should i think just be able to pull the data direct from the container specific chart.
For example i have a container called airbyte-webapp and so i can get its network usage via its own specific chart at /api/v1/data?chart=cgroup_airbyte-webapp.net_eth0
Usually, the issue with such questions comes from Netdata not being granted the access required to identify the docker container.
I'd take a look at https://learn.netdata.cloud/docs/agent/packaging/docker/#docker-container-names-resolution and go through https://github.com/netdata/netdata/issues/6882 as well.
