Abstract

An apparatus includes at least one port to exchange packets of data with one or more networks and a user interface circuit that allows a user to input a plurality of event classification rules. Each of the event classification rules describes at least one event characteristic for an event in the apparatus. At least one of the event classification rules describes a plurality of the event characteristics. At least two of the event characteristics are selected from a group including a reboot of the apparatus, a change in state of a processor of the apparatus, a change in state of a memory of the apparatus, a change in state of the at least one port of the apparatus, a change in an attribute of a network interface of the apparatus, a user login, and a user logout. The change in state of the at least one port is generated by a change in spanning tree mode. The apparatus further includes an event classifier to identify events having the at least one event characteristic described by any of the event classification rules. The apparatus further includes a plurality of event counters each to count the events identified by the event classifier for a respective one of the event classification rules.
