Memory graph always at 0 under raspberry pi

[Enissay]

Describe the bug
I am running an instance of Dozzle on RPI 4B, Debian 11 x64. While the CPU graph shows some usage, the MEM is always nul

Expected behavior
Clearly the MEM graph is not properly working

I went and investigated the reasons and it seems to be an issue with docker on arm64: docker/for-linux#1112

Which is confirmed when testing on my RPI4:

$ docker stats CONTAINER_ID
CONTAINER ID   NAME                                       CPU %     MEM USAGE / LIMIT   MEM %     NET I/O        BLOCK I/O    PIDS
2daa465456f1   blah_app.1.wsel6v0x                        0.01%     0B / 0B             0.00%     274kB / 44kB   120MB / 0B   33

I simply fixed it by adding cgroup_memory=1 cgroup_enable=memory to the end of line in /boot/cmdline.txt followed by a reboot... If anyone had issues still, please refer to the link for more details...

Okay, I just found out it is a duplicate of #1965... Grrrr...

Yep. It is also in the README at the bottom in the FAQ section.
