1. A method for setting expressions at an agent, the method comprising:
- receiving a Simple Network Management Protocol (SNMP) message from a management station specifying objects for a notification supported by the agent and expressions based on said objects, said objects comprising management information and said notification corresponding to an event;
setting said expressions of variables contained in a management information base at the agent;
evaluating at least one of said expressions when the agent generates the notification containing the object on which the expression is based; and
performing an action based on the evaluated expression.
