AgiMonitor: a remote database monitoring tool for main memory database

摘要

Database monitoring and analysis tools play an important role in the database system performance analysis, optimization, and fault tracking. In recent years, main memory database technology has become one of the important topics in the database research field. A suitable database performance analysis, optimizing tool is also needed in memory database development and use. Additionally for the specific problems encountered in the process of main memory database's development, a memory database monitoring tool, named AgiMonitor, is designed and implemented. It implements the database's real-time monitoring remotely and feedback control with several techniques, such as the active-passive mode based on message processing management, local message storage and asynchronous message handling scheme, variable monitoring based on address replication, and an information feedback mechanism in which variable values can be written back. Finally, AgiMonitor's functions are demonstrated through the prototype system.
