Abstract
A new event forwarding discriminator (EFD) EFD named the persistent/impervious event forwarding discriminator (PI EFD) is described herein. The PI EFD is monitored by the agent infrastructure in such a way that if the agent goes down, and thus the PI EFD goes down, the agent rebuilds or restores the PI EFD with all its attributes. The PI EFD immediately creates an event notification indicating a create PI EFD event has occurred. This event notification is of the type passed by the PI EFD to the manager. The manager then knows the poll its other EFDs at the agent and recreate them as necessary. To foil rogue managers, the PI EFD can not be deleted by other managers. Also, the PI EFD has limited attributes that can be changed. A rogue manager can only add himself to the destination list; it can not otherwise change the attributes of the PI EFD.
