Abstract: A system and method of using metrics to control throttling and swapping in a message processing system is provided. A workload status of a message processing system is determined, and the system polls for a new message according to the workload status. The message processing system identifies a blocked instance and calculates an expected idle time for the blocked instance. The system dehydrates the blocked instance if the expected idle time exceeds a predetermined threshold.

Abstract: Method and system for performance monitoring of distributed applications. A sensor intercepts every request of service for a server that is generated on a client. If the request meets a filtering condition (for example, defined by the address of the server, the web page from which the request is originated and/or the selected link) the measuring of a corresponding transaction on the client is enabled; at the same time, the request is updated by inserting a correlator. The request is then transmitted to the server. If the request includes the correlator, the measuring of a sub-transaction originating from the request is also enabled on the server. The parameters measured on the client and on the server are then associated with the correlator.

Abstract: A method and apparatus for scalable inquiries in a network of communicating peers are provided. The method and apparatus of the present invention make use of communal filters and randomization to determine which client devices will output a message that is to be broadcast to a community of client devices. Each message is assigned a probability value that is determined based on various criteria or may be determined randomly. The message is then transmitted to the client devices who apply their own respective display criteria to the message parameters to determine if the message is one that is of interest to the user of the client device. If the message is not of interest to the user of the client device, the message is discarded. If the message is of interest to the user, logic is applied to the parameters of the message to determine whether the message should be displayed to the user or not.
