Is there some commands to test memory subsystem of cgroup only?

[rameble]

I use ./runltp -f controllers to test cgroup function. It is very time-consuming.

I want to only test cgroup memory subsystem. Is there some commands to test only memory subsystem of cgroup?

Thanks.

The easiest way is probably to copy the controllers runtest file and delete everything you are not interested in from the copy.

I guess that it would make sense to split the cgroup runtest file into several based on the controllers it's testing.

+1 for split runtest files

If you want to try run the individual test of cgroup in your ltp environment. From path /opt/ltp/testcases/bin/ there are some cgroup invidual test cases, worth checking.

$ ./cgroup_core02 tst_test.c:1558: TINFO: Timeout per run is 0h 00m 30s cgroup_core02.c:84: TPASS: test_lesser_ns_open passed: ENOENT (2)

Summary: passed 1 failed 0 broken 0 skipped 0 warnings 0

$ ./cgroup_core01 tst_test.c:1558: TINFO: Timeout per run is 0h 00m 30s cgroup_core01.c:63: TPASS: test_lesser_euid_open passed: EACCES (13)

Summary: passed 1 failed 0 broken 0 skipped 0 warnings 0

FYI - There are few other tests in the same location which needs preconfig test data, which gets set as part of the complete run of cgroup controller tests I suppose

/opt/ltp/testcases/bin/

And also while running the tests, you can also use this systemd command to monitor cgroup memory controller stats on your system.

$ systemd-cgls memory

and

$ systemd-cgtop
