Hello !
I like to fire a rule when none of my facts match a certain attribute.
(deftemplate node (slot ip) (slot status)) ; status can be up or down
(defrule all-nodes-are-down
(not (exists (node (status up))))
=> (printout t "All nodes are down !" crlf))
....
(assert (node (ip "1.1.1.1") (status down)))
(assert (node (ip "2.2.2.2") (status down)))
(run)
.....
For some reason this does not work.
What am I doing wrong here ?
Thanx for your help !
Matthias
