On systemd-based systems, cgroup v2 can be enabled by adding systemd.unified_cgroup_hierarchy=1 Changing cgroup versionĬhanging cgroup version requires rebooting the entire system. See /sys/fs/cgroup/ntrollers to the available controllers. On cgroup v2 hosts, the content of /proc/cgroups isn’t meaningful.

Group, while /lxc/pumpkin indicates that the process is a member of a means the process has not been assigned to a The control group is shown as a path relative to the root of You can also look at /proc//cgroup to see which control groups a processīelongs to. Known to the system, the hierarchy they belong to, and how many groups they contain. You can look into /proc/cgroups to see the different control group subsystems Refer to the subsection that corresponds to your cgroup version.Ĭgroup v2 is used by default on the following distributions: If /sys/fs/cgroup/ntrollers is present on your system, you are using v2, The file layout of cgroups is significantly different between v1 and v2. To figure out where your control groups are mounted, you can run: You see a bunch of files in that directory, and possibly some directories In that case, instead of seeing the sub-directories, On older systems, the control groups might be mounted on /cgroup, withoutĭistinct hierarchies. each sub-directory actually corresponds to a different That directory, you see multiple sub-directories, called devices,įreezer, blkio, etc. In recentĭistros, you should find this filesystem under /sys/fs/cgroup.

This is relevant for “pure” LXCĬontainers, as well as for Docker containers.Ĭontrol groups are exposed through a pseudo-filesystem. Which not only track groups of processes, but also expose metrics aboutĬPU, memory, and block I/O usage. More details about the docker stats command.
