Check Swap in/out rate instead of percentage free?

I am new to the list, so sorry if this is out of order...you should be able to
write a plugin using mostly what you have above, without outputting to a file...I
think this would do it (replace 100 with the number of pages you want as a
threshold):

-----
#!/bin/bash

PAGES=`grep pswpout /proc/vmstat | cut -d " " -f2`

  if [ $PAGES -gt 100 ]; then
     echo "Swapping $PAGES pages ALERT"
     exit 1
  fi

echo "Swapping $PAGES pages OK"
exit 0

Now if anybody has any clue as to my LDAP/xinetd question, I would be very
grateful! :)
