massive network activity reported for cAdvisor #3439

Open s0170071 opened 10 months ago

Hi all, I am running cAdvisor 0.47.2 on a n RPI4 in docker . The network bandwidth reported for just the cAdvisor container is massive:

Thats 10MBytes per second sent data. Is the measurement false or is it actually sending data somewhere ?

Edit: the traffic stops if I close the browser window. If I open it again, the network traffic resumes:

Done some more digging: on my pi there is a docker system. The traffic appears as tx in network eth0 and br0 and appears as RX in the network pi_default. That would mean that external traffic is going into the docker network, and yet docker stats lists cAdvisor as sender of that traffic.
