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.
