Abstract: The invention facilitates improved configuration of computer network data collection. In one respect, the invention is a method for determining a network data collection configuration for an entity utilizing a computer network. The method determines which nodes in the network are associated with the entity, reads a view definition associated with the entity and determines which network variables are components of the health score, selects from the nodes associated with the entity those nodes that are components of the view, and produces a configuration file that specifies the network variables for each corresponding selected node. The data collection preferably utilizes the SNMP protocol. The determining step preferably queries a database that stores entity-node associations. The view definition is preferably an XML file and refers to all nodes of a particular device type, so that the selecting step can filter network nodes by device type.

Abstract: Apparatus and methods facilitate customizable and extensible performance monitoring of a computer network. One method accepts a composite score definition in terms of N system variables, wherein N?2; determines N raw data values, each raw data value corresponding to one of the N system variables; computes the composite score in accordance with the definition using the N raw data values as inputs; and outputs the composite score. The composite score definition is preferably in the form of a markup language, such as XML. The composite score definition preferably comprises, for each of the N system variables, a mapping and a weight. Preferably the composite score is displayed in at least one graphic form, such as a dial gauge, a bar indicator or a number, on a hypertext page. The hypertext page preferably contains one or more links to hypertext pages containing information regarding the scores and/or raw data values from which the composite score is derived.

Abstract: A system and method synchronizes multiple data stores and achieves data consistency in a non-transactional multiprocessing computer system. Processes are paused and later resumed according to their position in a dependency tree of the system. The data input sources of the system are in effect disabled and any data flow currently in progress in the system is flushed out the various data flow paths to the different data stores. When this process is complete, each of the multiple data stores is synchronized and the data is in a consistent state.
