NAME

cgmanager - a daemon to manage cgroups  

SYNOPSIS

cgmanager [OPTION]...  

DESCRIPTION

cgmanager is a daemon to manage cgroups. Programs and users can make D-Bus requests to administer cgroups over which they have privilege. To ensure that users may not exceed their privilege in manipulating cgroups, the cgroup manager accepts regular D-Bus requests only from tasks within its own process-id and user namespaces. For tasks in private namespaces (such as containers), SCM-enhanced D-Bus calls are available. Using these manually is not recommended. Rather, each container is advised to run a cgproxy, which will forward plain D-Bus requests as SCM-enhanced D-Bus requests to the host cgmanager.
