# cgmanager(8)

a daemon to manage cgroups

## 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.

## EXAMPLES

To create a new memory cgroup called 'compute', you can use:\
 dbus-send --print-reply --address=unix:path=/sys/fs/cgroup/cgmanager/sock --type=method\_call /org/linuxcontainers/cgmanager org.linuxcontainers.cgmanager0\_0.Create string:'memory' string:"compute" \> /dev/null 2\>&1\
 To set a limit of 100000,\
 dbus-send --print-reply --address=unix:path=/sys/fs/cgroup/cgmanager/sock --type=method\_call /org/linuxcontainers/cgmanager org.linuxcontainers.cgmanager0\_0.SetValue string:'memory' string:"compute" string:memory.limit\_in\_bytes int32:100000 \> /dev/null 2\>&1
