[INUG-Users] Proviso - OSPF formulas

[Henderson, James]

Technically speaking, you can run a collection formula at the device level (NULL subelement).  You'll need to use aggregation functions (IE sum/min/max/count/ave...) and some other trickery within the collection formula, but it is possible.

Have you created a discovery formula to create the resources you are going
to report on?  You can't run an OSPF collection against a device (NULL
subelement); you need a resource to collect against.  Just like interfaces
- you need to discover the interfaces, then collect interface statistics
against them.  The OSPF subelements you create should be indexed by the
same four indices that you have used in your collection formula.

Daniel, Michael,

OSPF is running.
Here is the test output from FormEdit:

End: End of Request



I just can't see why this should not work against Sub-Element~Devices~IP
Device group!?
