NAME

       ctop - Command line / text based Linux Containers monitoring tool

SYNOPSIS

       ctop [options]

DESCRIPTION

       ctop will help you see what's going on at the container level.  Basically, containers are a logical group
       of  processes  isolated  using  kernel's cgroups and namespaces. Recently, they have been made popular by
       Docker and they are also heavily used under the hood by systemd and a load of container tools  like  lxc,
       rocket, lmctfy and many others.

       Under  the  hood,  ctop  will  collect  all  metrics  it  can from cgroups in realtime and render them to
       instantly give you an overview of the global system health.

       It currently collects metrics related to cpu, memory and block IO usage  as  well  as  metadata  such  as
       owning  user  (mostly  for systemd based containers), uptime and attempts to guess the container managing
       technology behind.
