面向生物医学影像e-Science平台的审计监控系统

摘要

During Research in biomedical imaging and clinical applications for major diseases, it is often necessary to involve scientist of basic medicine, clinical medicine, physics and biomedical engineering for collaborative research. To do this, we built a grid-based biomedical image e-Science platform, providing data sharing and exchange between the different institutions. Due to the distribution of system and node heterogeneity, it is difficult to avoid the system hardware and software failures. Therefore, this paper designed an XMPP-based audit and monitoring system, which supports both real-time monitoring of each host, and auditing of the data business happening in e-Science. The system is running with e-Science platform, showing good convenient and soundness.%在面向重大疾病的生物医学成像与临床应用等研究中，常常需要包括基础医学、临床医学、物理学和生物医学工程多学科的科研工作者进行协同交互。为此采用网格技术构建了生物医学影像e-Science平台，实现了跨机构之间大数据的快速共享与交换。由于系统的分布性和节点的异构性，难以避免会碰到系统的软硬件故障。因此，设计了一种基于XMPP协议的审计监控系统，既对e-Science的各个主机系统资源进行实时监测，又对平台中数据业务进行审计跟踪。系统最终被部署应用在e-Science平台，具有良好的便捷性和稳健性。
