Abstract:
After analyzing the levels of large-scale parallel database monitor system, this paper realizes the dynamic monitor module in the middleware layer. This module adopts centralized monitor technology to get control information, and uses the subscribe and publish mechanism of ICE Storm to realize the publication and treatment of monitor message, and enables user to obtain real-time monitor information through Ajax and Web technologies, thereby ensuring the efficient services of database system and greatly facilitating the management in the complex database system.
