To display the value of a subsystem parameter, use the
cgget command. The following example shows how
to display the memory statistics for the cgroup
hipri
.
# cgget -r memory.stat hipri
rss 168132608
mapped_file 57577472
.
.
.
You can use the cgset command to change the
value of subsystem parameters for a cgroup. The next example
removes input throttling from the device
/dev/sda1
for the cgroup
iocap1
by setting the value of
blkio.throttle.read_bps_device
to 0.
# cgset -r blkio.throttle.read_bps_device="8:1 0" iocap1
Any change that you make to a parameter is effective only while
the cgconfig service continues to run. The
cgset command does not write the new value to
the configuration file, /etc/cgconfig.conf
. You
can use the cgsnapshot command to display the
current cgroup configuration in a form that you can use as the
basis for a new /etc/cgconfig.conf
file.
# cgsnapshot -s > current_cgconfig.conf

,
cgset(1)
, and cgsnapshot(1)
manual pages.
