This is just my idea how to extend visualization capabilities of NPM. The virtual managed object, created by a NPM admin, could be controlled programmatically by an alert action to e. g. change its status. Then it could be added to a group that would reflect its status.
The problem I'd like to solve is to create a high level NOC view that would visualize the presence of a Syslog message. The Syslog message is the only way that a custom developed application would report its status.
I believe that such virtual managed object could be useful in other cases, too.
