Jie Yu updated MESOS-1989:
--------------------------
Sprint: Twitter Mesos Q4 Sprint 2
Affects Version/s: 0.20.1
> 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
> Affects Versions: 0.20.1
> 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.
