Jie Yu created MESOS-1989:
-----------------------------
Summary: Container network stats reported by the port mapping
isolator is the reverse of the actual network stats.
Key: MESOS-1989
URL: https://issues.apache.org/jira/browse/MESOS-1989
Project: Mesos
Issue Type: Bug
Reporter: Jie Yu
Looks like the TX/RX network stats reported is the reverse of the actual
network stats. The reason is because on simply get TX/RX data from veth on the
host.
Since veth pair is a tunnel, the ingress of veth on host is the egress of eth0
in container (and vice versa). Therefore, we need to flip the data we got from
veth.
