How to obtain that since ulimit is a bash command(?). sudo -u vdsm bash 
ulimit -a returns permission denied

There is a /etc/security/limits.d/99-vdsm.conf which has limits for 4096 
proc and 3*4096 nofiles.

Found this:

return-limits(){

      for process in $@; do
           process_pids=`ps -C $process -o pid --no-headers | cut -d " " -f 2`

           if [ -z $@ ]; then
              echo "[no $process running]"
           else
              for pid in $process_pids; do
                    echo "[$process #$pid -- limits]"
                    cat /proc/$pid/limits
              done
           fi

      done

}

running that:
return-limits vdsm:
