Let's run this in a LXD container:
container# cat /dev/urandom|gzip - >/dev/null
Then see what CPU usage "ps auxf" shows (3rd column):
container# ps auxf
USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND
root 18177 0.0 0.0 4632 1584 pts/0 R+ 16:47 11:33 |
\_ gzip -
(...)
Then, the same in the host:
host# ps auxf
USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND
100000 14878 99.7 0.0 4632 1584 pts/0 R+ 16:47 11:47 |
| \_ gzip -
(...)
Why does the container show it incorrectly as 0.0?
