NAME¶
lssubsys - list hierarchies containing given subsystem
SYNOPSIS¶
lssubsys [
-m|--mount-points] [
-M|--all-mount-points] [
controller] [...]
lssubsys [
-m|--mount-points] [
-M|--all-mount-points] [
-i|--hierarchies] [
-a|--all]
lssubsys [
-h|--help]
DESCRIPTION¶
lssubsys list the hierarchies containing the given subsystem(s). If no
subsystem is defined, it displays all mounted hierarchies.
- controller
- defines the subsystem whose hierarchy is shown. If this parameter is not
used, the command will list all mounted subsystems.
- -m, --mount-points
- Display mount points. Only the first mount points of shown hierarchies are
displayed.
- -M, --all-mount-points
- Display mount points. All mount points of shown hierarchies are displayed,
each on separate line.
- -a, --all
- Display all subsystems (including unmounted ones).
- -i, --hierarchies
- Display the attached hierarchy number if the subsystem is in a hierarchy.
If the option -m is also used, the hierarchy number is shown only
for unmounted hierarchies.
- -h, --help
- Display help and exit.
EXAMPLE¶
The command
lssubsys -am lists all subsystems which are present in the
system, mounted ones will be shown with their mount point:
$ lssubsys -am
ns
cpuset
cpu,devices
cpuacct /cgroup/cpuacct
memory /cgroup/memory
freezer /cgroup/freezer
net_cls /cgroup/net_cls
The command
lssubsys -ami lists all subsystems which are present in the
system, mounted subsystems are listed with their mount points, unmounted ones
which are in a hierarchy are listed with their hierarchy number:
$ lssubsys -ami
ns
cpuset 5
cpu,devices 6
cpuacct /cgroup/cpuacct
memory /cgroup/memory
freezer /cgroup/freezer
net_cls /cgroup/net_cls
ENVIRONMENT VARIABLES¶
- CGROUP_LOGLEVEL
- controls verbosity of the tool. Allowed values are DEBUG,
