Application response monitor

A computer-based method of monitoring networked application responsiveness, the method comprising:

• detecting an application instance that has a stream of application events;
• instantiating a finite state machine to recognize transactions in the stream of application events for the application instance, the finite state machine including a collection of states and a collection of transitions, each such transition having criteria for events that qualify to transition between a source state for the transition and a destination state for the transition, the source state and the destination state being among the collection of states;
• associating a first token with an initial state in the collection of states;
• processing the stream of application events sequentially, including, for each such event, comparing the event to a processed transition in the collection of transitions and associating an event token with the destination state of the processed transition if the event satisfies the criteria of the processed transition;
• and
• recognizing a transaction if a final state in the collection of states is associated with the event token for a candidate event in the stream of application events.

A computer-based method of monitoring networked application responsiveness, the method comprising:

• receiving a message that specifies a measure of responsiveness, a client, a server, and a networked service;
• selecting from a database a path corresponding to the client and the server, and a client set corresponding to the client;
• and
• adding the measure of responsiveness to an aggregate measure of responsiveness for a plurality of clients, the aggregate measure of responsiveness selected according to the client set, the path, and the networked service.
