Lxc-info: How is "Memory use" calculated?


#1

Hello,

For the command lxc-info, I’m trying to find out how is Memory use entry calculated or what’s the source it takes from?
I compared with /proc/meminfo, and none of the numbers match.

Any help is appreciated. Thanks.

Hi!

You would need a tool that understands containers or understands control groups (which relate to containers).
Therefore, use

systemd-cgtop

You can hit ? for help, p to sort by path, etc.
If your container is called mycontainer, then look at the memory for /lxc.payload/mycontainer.
