CHANGELOGS:
CHANGELOG v4
* incorporate dhaval feedback:
* whitelist -> blacklist
* add cgroup_free_cgroup
CHANGELOG v3
* white/blacklist is cached
* incorporate jsafraneks feedback
CHANGELOG v2
* add whitelist which describe the set of variables which can be dealt
by
cgsnapshot without any problem (the values which with which have cgsnapshot
the problems are there with TODO comment and the reason) without -s option
the skipped variables are output with the warning text
* add the possibility to set the whitelist file
* add the possibility to redirect the output
CHANGELOG v1
* more verbose comments
* tune the variable names/description/usage in display_controller_data
function
* remove unnecesary .stat exception
SYNOPSIS:
cgsnapshot [-h] [-s] [-b] [--blacklist-file file] [-f output_file]
[controller] [...]
Generate the configuration file from the current hierarchie(s) of
control groups
-h, --help Display this help
-s, --silent Ignore all warnings
-b, --blacklist Display only variables from whitelist (default
/etc/cgsnapshot_blacklist.conf)
--blacklist-file file Set the whitelist configuration file
-f, --file Redirect the output to output_file
the output have the same format as cgconfig.conf file (the values are
in commas)
there is also whitelist, which contains all controllers which are dealt
without any problem (there are several TODOS like devices and so on) if
EXAMPLE:
$ /home/varekova/bg/libcgroup/20100719/libcg/src/tools/cgsnapshot -n
# Configuration file generated by cgsnapshot
mount {
cpuset = /cgroup/cpuset;
cpu = /cgroup/devices;
cpuacct = /cgroup/memoryd;
memory = /cgroup/memory;
devices = /cgroup/devices;
freezer = /cgroup/freezer;
net_cls = /cgroup/net_cls;
}
group daemons {
perm {
admin {
uid = root;
gid = root;
}
task {
uid = root;
gid = root;
}
}
cpuset {
cpuset.memory_spread_slab="0";
cpuset.memory_spread_page="0";
cpuset.memory_migrate="0";
cpuset.sched_relax_domain_level="-1";
cpuset.sched_load_balance="1";
cpuset.mem_hardwall="0";
cpuset.mem_exclusive="0";
cpuset.cpu_exclusive="0";
}
