Try running etop, this helped me find a CPU Spin of my own.

My end result looked a little different but given the two examples it
should help you get started.

Also keep in mind this is apart of my init script. I attached an ARG
to run this etop command.

etop ()
    echo "--------------------------------------------------------------------"
    echo ""
    echo "IMPORTANT: we will attempt to attach a running ejabberd node"
    echo "If an ERROR is printed, it means the connection was not succesful."
    echo ""
    echo "To detach this shell from ejabberd, press:"
    echo "  control+c, control+c"
    echo ""
    echo "--------------------------------------------------------------------"
    echo ""
    /sbin/runuser -s /bin/bash - ejabberd -c \
    "$ERL \
      $NAME ${NODE}etop \
      -hidden \
      -s etop \
      -s erlang halt \
      -output text \
      -tracing off \
      -node $ERLANG_NODE"
