This paper describes a monitoring tool for grid computing[5], called visPerf. It is difficult to see the status of a working production grid system without a customized monitoring system. The status includes many details of the system such as system running information, performance changes, system/software failures, security issues and so forth. Most grid middleware provide a simple monitoring tool for their systems, or provide simple tools for checking the status of the system. visPerf is a general purpose grid monitoring tool for visualizing, investigating, and controlling the system in a distributed manner. visPerf is a system based on a distributed monitoring sensor (visSensor) in which the sensor uses methods to monitor the grid middleware’s status with little or no modifications to the underlying system. visSensor uses two methods to capture the status: indirect and direct interfaces. The indirect interface uses the log information generated in the run-time of the middleware...
