Difference in memory measure between top and cgtop
Issue
I've configured systemd to gather memory and cpu consumption for cgroups in /etc/systemd/system.conf
DefaultCPUAccounting=yes
DefaultMemoryAccounting=yes
Reloaded systemd and observed the systemd-cgtop output.
$ systemd-cgtop
Path Tasks %CPU Memory Input/s Output/s
/system.slice/firewalld.service 1 - 33.1M - -
The Memory value is different from the RSS column in top.
USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND
root 663 0.0 0.7 357860 28900 ? Ssl 09:21 0:00 /usr/bin/python -Es /usr/sbin/firewalld --nofork --nopid
What does systemd-cgtop account in for memory usage?
