Someone pass along the top incantation to limit output to all processes in 1x container

I think this is a simple as…

  1. Finding the pid of 1x [lxc monitor] process.

  2. Then passing some arg to top to track this ppid + all children pids, as they… come + go…

I can’t seem to figure out how to do this.

If someone has the top incantation, pass it along.

I’m running Ubuntu Focal at machine level.
