Bug ID: 1096286
           Summary: "docker top all" doesn't show processes when
                    --tty=false
           Product: Red Hat Enterprise Linux 7
           Version: 7.1
         Component: docker

+++ This bug was initially created as a clone of Bug #1088259 +++
After using the same magic required for the upstream docker 0.10 this behaves
the same on RHEL docker-0.10.0-8.el7.x86_64
Description of problem:
Hi guys, when I run docker with --tty=false, the `docker top $NAME all` doesn't
show any processes (just headers). When using only `docker top $NAME` it shows
them...
Also the `ps` command inside container works, but `ps all` does not.
Version-Release number of selected component (if applicable):
docker-0.10.0-8.el7.x86_64
docker-io-0.9.0-3.fc20.x86_64
How reproducible:
always
Steps to Reproduce:
1. docker run -i --tty=false fedora bash
2. docker logs $NAME
Actual results:
F                   UID                 PID                 PPID               
PRI                 NI                  VSZ                 RSS                
WCHAN               STAT                TTY                 TIME               
COMMAND
Expected results:
F                   UID                 PID                 PPID               
PRI                 NI                  VSZ                 RSS                
WCHAN               STAT                TTY                 TIME               
COMMAND
1                   0                   24006               23954

Can't reproduce with the upstream Docker version 0.10.0, build dc9c28f/0.10.0
top doesn't work at all (due of
https://bugzilla.redhat.com/show_bug.cgi?id=1088125 )

OK I moved it to the old cgroup location and the results are the same. So
booth, fedora docker-io-0.9.0-3.fc20.x86_64 and upstream dc9c28f/0.10.0 are
unable to list processes using `all` argument in non-tty mode.
