There are many ways to do this. I think the easiest way would be to create
a database field (see the files under the /usr/OV/fields/C directory for
reference and the Netview documentation). If you create the field with the
capability flag and locate flags, then either the Netview GUI (or a simple C
program) can update that field. Then you could use a query database field
node in your ruleset to forward the event to the next node (your action) if
that field has a certain value. If you have to add additional servers, it
is pretty easy. You could also use the field to make a collection which can
be monitored visually.
For example your field could be "Critical Servers" and it can be a boolean
field or string field. Set it to "TRUE" for those servers you want to take
your actions on. Make your ruleset such that if you get a node down event,
the event will be forwarded to a "Query Database Field" node. The event
attribute you will want to use for the object will be "2" (for the node down
event this is the object name in the database). Use the dialog box to see
if your field "Critical Servers" is set to "TRUE" for that object. If it
is, pass it to the next node (page or whatever node you want).
