Abstract: A method for monitoring performance of an application system which is distributed across a plurality of network connected nodes, comprising: generating a hierarchical model for the application system, the hierarchical model having a plurality of levels, each level including components of a span specific to that level; mapping the application system onto the hierarchical model according to a network topology of the application system; monitoring network traffic between the plurality of network connected nodes of the application system to gather network traffic data; assembling the network traffic data into application messages; correlating the application messages into sets of one or more application messages that are causally associated in accordance with the hierarchical model, wherein the sets of causally associated application messages constitute transactions corresponding to a lowest level of the hierarchical model; and, generating records of individual transactions occurring within the application system

Abstract: A method for executing an application, comprising: receiving data associated with the application; storing the data in a data buffer in a data store; selecting one or more module instances to define a function of the application, each module instance for independently performing a respective aspect of the function, each module instance independently accessing the data buffer directly from the data store to process data contained therein to perform its aspect of the function; and, using a processor, initiating operation of the one or more module instances in accordance with a schedule defined by one or more routing rules, the one or more routing rules for routing a pointer to the data, as stored in the data buffer, between the one or more module instances to thereby perform the function without passing the data itself between the one or more module instances.
