systemd-cgls - Recursively show control group contents SYNOPSIS
systemd-cgls [OPTIONS...] [CGROUP...] systemd-cgls [OPTIONS...] --unit|--user-unit [UNIT...] DESCRIPTION
systemd-cgls recursively shows the contents of the selected Linux control group hierarchy in a tree. If arguments are specified, shows all member processes of the specified control groups plus all their subgroups and their members. The control groups may either be specified by their full file paths or are assumed in the systemd control group hierarchy. If no argument is specified and the current working directory is beneath the control group mount point /sys/fs/cgroup, shows the contents of the control group the working directory refers to. Otherwise, the full systemd control group hierarchy is shown. By default, empty control groups are not shown. OPTIONS
The following options are understood: --all Do not hide empty control groups in the output. -l, --full Do not ellipsize process tree members. -u, --unit Show cgroup subtrees for the specified units. --user-unit Show cgroup subtrees for the specified user units. -k Include kernel threads in output. -M MACHINE, --machine=MACHINE Limit control groups shown to the part corresponding to the container MACHINE. -h, --help Print a short help text and exit. --version Print a short version string and exit. --no-pager Do not pipe output into a pager. EXIT STATUS
On success, 0 is returned, a non-zero failure code otherwise. SEE ALSO

systemd-cgtop - Show top control groups by their resource usage SYNOPSIS
systemd-cgtop [OPTIONS...] DESCRIPTION
systemd-cgtop shows the top control groups of the local Linux control group hierarchy, ordered by their CPU, memory and disk I/O load. The display is refreshed in regular intervals (by default every 1s), similar in style to top(1). Resource usage is only accounted for control groups in the relevant hierarchy, i.e. CPU usage is only accounted for control groups in the cpuacct hierarchy, memory usage only for those in memory and disk I/O usage for those in blkio. systemd(1) by default places all services in their own control group in the cpuacct hierarchy, but not in memory nor blkio. If resource monitoring for these resources is required it is recommended to add blkio and memory to the DefaultControllers= setting in /etc/systemd/system.conf (see systemd.conf(5) for details). Alternatively, it is possible to enable resource accounting individually for services, by making use of the ControlGroup= option in the unit files (See systemd.exec(5) for details). To emphasize this: unless blkio and memory are enabled for the services in question with either of the options suggested above no resource accounting will be available for system services and the data shown by systemd-cgtop will be incomplete. OPTIONS
The following options are understood: -h, --help Prints a short help text and exits. -p Order by control group path name. -t Order by number of tasks in control group (i.e. threads and processes). -c Order by CPU load. -m Order by memory usage. -i Order by disk I/O load. -d, --delay= Specify refresh delay in seconds (or if one of ms, us, min is specified as unit in this time unit). --depth= Maximum control group tree traversal depth. Specifies how deep systemd-cgtop shall traverse the control group hierarchies. If 0 is specified only the root group is monitored, for 1 only the first level of control groups is monitored, and so on. Defaults to 2. KEYS
systemd-cgtop is an interactive tool and may be controlled via user input using the following keys: h Shows a short help text. SPACE Immediately refresh output. q Terminate the program. p, t, c, m, i Change ordering of control groups by path, number of tasks, CPU load, memory usage resp. IO load. +, - Increase, resp. decrease refresh delay. EXIT STATUS
On success 0 is returned, a non-zero failure code otherwise. SEE ALSO
