This doesn't do the graph, but it will give you the status you want:

  #!/bin/sh

  # Change this command to the one you use to collect the data
  getthestatus >$BBTMP/corestat.$$

  OUTCOUNT=`grep -c " out " $BBTMP/corestat.$$`
  if test "$OUTCOUNT" = "4"
  then
     COLOR=red
  elif test "$OUTCOUNT" -gt 0
  then
     COLOR=yellow
  else
     COLOR=green
  fi

  # Note: This command spans multiple lines
  $BB $BBDISP "status $MACHINE.cores $COLOR `date`

  $OUTCOUNT cores out

  `cat $BBTMP/corestat.$$
  "

  rm $BBTMP/corestat.$$
  exit 0
