In one embodiment of the present invention, a content delivery network (CDN) monitoring system manages a CDN. The CDN monitoring system includes finite state machines (FSMs), and the current states of the FSMs reflect characteristics and/or behaviors associated with the CDN. In operation, the CDN monitoring system computes actions based on current states and/or metrics associated with the CDN. The actions may cause one or more of the FSMs execute state transitions. As part of a state transition, the current state of the FSM changes and an event is generated. The event triggers an event handler that may perform any type of management operations, such as generating performance reports and rerouting client requests. Notably, because each current state may be an aggregation of other current states, the CDN monitoring system may be configured to compute current states that accurately represent complex interactions between components within the CDN.
