One RRD with just one DS

[script
  counts number of instances in oid 1.3.6.1.2.1.10.12.3.3.1.9 on each
  of these devices: stjoe, paramus, artesia, cambridge

  stjoe and cambridge are summed into minn

  In one call do three updates to the same database:
      update $time:$minn
      update $time:$paramus
      update $time:$artesia
]

If you call this script a few times 300 seconds apart (!) then I expect
the following to happen:
 - the database is updated with the sum of stjoe and cambridge
 - the program gives an error because it cannot update again using
   the value from paramus
 - the program gives an error because it cannot update again using
   the value from artesia

So I guess it never worked at all and you are currently not doing
enough updates to actually see the $minn values appearing in the RRD.
