[JOduMonT]

which show docker stats with name.

If you use it, then I just merge it.

But wouldn't it be good to have stats, just from the current docker-compose?

[JOduMonT]

you means something like that ?
# docker-compose ps | grep Up | awk '{print $1}' | tr "\\n" " " | xargs --no-run-if-empty sudo docker stats

this one is good if you want to know for a specific set of dockers

but with \ # libre stats
you could see all of them

But, if you have, I'm always welling to learn a better way to do ;)
