Public bug reported:
I've been testing oomd and hoping it would just work out of the box.
>From what I can tell it doesn't seem to work at all for excess CPU (or memory
>for that matter) although I may be misunderstanding important matters but
>current documentation is insufficient for me to do better.
I've been trying to check the cpu related rules:
* User pressure above 60 for 30 s
* System pressure above 80 for 60 s
I disable oomd on the system using
$ systemctl stop oomd
I then run it using the command:
$ sudo /usr/bin/oomd --config /etc/oomd/oomd.json --cgroup-fs
/sys/fs/cgroup/unified
The oomd.json is the default for the Ubuntu 20.10 package.
I have previously changed my linux boot parameters on the command line
to include systemd.unified_cgroup_hierarchy=1.
I am running Ubuntu 20.10:
$ uname -a
Linux XPS-13-9360 5.8.0-33-generic #36-Ubuntu SMP Wed Dec 9 09:14:40 UTC 2020
x86_64 x86_64 x86_64 GNU/Linux
$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 20.10
Release: 20.10
Codename: groovy
I then test by doing a command like:
$ stress -c 150
and monitor the system pressure using something like:
$ cat /proc/pressure/cpu
some avg10=98.91 avg60=79.66 avg300=29.70 total=107155291
As far as I can tell oomd takes and tries to take no action.
I'd be happy to take some debugging suggestions or provide further information.
