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.
