Rancher not showing statistic of container

I install rancher server and host (on same machine), but it don’t show usage statistic on any container (just show “connecting…”, on host statistic everything is good).

Server started with command:

docker run --name rancher -p 8080:8080 rancher/server

And agent:

docker run -d --privileged -e  CATTLE_AGENT_IP=<IP>...

I checked logs on server and agent, but no error into them.

Docker version 1.8.3
Rancher server version 0.44.0
Rancher OS version 0.4.0

What I do wrong?

This is a known issue.
