Abstract: A method, apparatus, and article of manufacture for computer-implemented creation of customized tree. A customized tree is created in a computer from an original tree. The original tree contains objects from a data storage device connected to the computer. One or more objects are selected from the original tree to be contained in the customized tree in response to user input. The selected objects are linked in a user-specified manner.

Abstract: The present invention discloses a method, apparatus, and article of manufacture for monitoring performance of a parallel database in a computer. In accordance with the present invention, the parallel database is stored on a data storage device in the computer. Groups of database nodes are identified. Collection time periods for collecting performance statistics from the identified group of database nodes are determined. Performance statistics are periodically collected from a subset of each identified group of nodes during the collection time periods. The collected performance statistics are stored in a memory connected to the computer and re-used when collecting performance statistics from one or more groups of database nodes in a succeeding collection time period.

Abstract: A dynamic monitoring system for monitoring a computer system. The monitoring system is based on an optimized distributed policies or rules evaluation knowledge-base for monitoring the current state and conditions of the computer system in real-time. The monitoring system is further designed to monitor and dynamically reconfigure itself in real-time, based on the changing state and conditions of the computer system being monitored. The dynamic monitoring system continuously changes and adjusts to the present state of the computer system.

Abstract: A method and apparatus of monitoring a computer system having two or more managed systems, by utilizing an optimized distributed policies or rules evaluation knowledge-base. The computer systems includes a subsystem designated as the central point of control and one or more subsystems designated as managed systems. Each of the subsystems include a monitoring agent that is fully-automated and optimized to improve performance of the computer system. A monitoring agent includes watchdog agents, rule evaluator modules and action modules for monitoring various characteristics of the computer system. The monitoring agents are optimized by evaluating policies or rules locally when possible and globally when required.
