| Popis: | 93 As the related technologies of internet, hardware, and software progress rapidly, some developments of the medical information system have been distributed, complex, huge, and diverse. In such environment, a little problem will cause the whole system to fail and the system manager can not find the problem immediately. We hope that there is a system which can help system manager to solve the problem correctly and quickly. Furthermore, we integrate the fault tolerance into the medical information system. Our laboratory develops a picture management system and a simulation system for teaching. The main function of the picture management system is to manage the collection and distribution. The simulation system for teaching is an online learning system. By means of interaction with the system, the users study and discuss the medical knowledge. The users also can be tested in the system. However, because these two systems are distributed in the whole hospital, we can not perceive and deal with the problem immediately when the systems fail. In this thesis, we monitor each node in the system. Vertically, the system is divided into network layer, operating system layer, and application layer by logic. Horizontally, the monitor of each layer is divided into master monitoring module and slave monitoring module. Not only the resource usage of each server and the performance of each object, but also the Log files of each server and application are collected. Therefore, monitoring the operating situation of each node in the whole network is achieved. |
