docker - Network usage data between every two pairs of docker containers

Question

I have a few micro-services running in docker containers (One service in each container).

How do I find out the network usage between every two pair of docker containers? So that I can make a graph such that I have containers as vertices and on edges I have the amount of bytes transmitted/received.

I used cAdvisor, but it gives me the overall network usage of each container.

从 docker stats 开始：

$ docker stats
CONTAINER ID        NAME                CPU %               MEM USAGE / LIMIT     MEM %               NET I/O             BLOCK I/O           PIDS
