摘要
【目的】帮助系统管理员从复杂的结构中寻找系统故障的根源,以进一步提高电网管理信息系统的可靠性。【方法】将配置管理数据库(Configuration management database,CMDB)结合故障树分析法(Fault tree analysis,FTA)进行故障规则推理,再通过CMDB确定故障设备之间的关系,从而通过监控告警结合故障规则分析定位到故障根源,并进行实例验证。【结果】基于CMDB的规则推理的故障定位技术可以有效地梳理信息系统各功能组件和故障表征之间的关系,实现快速故障定位。【结论】该技术可有效提高系统的可用率和运行率。
【Objective】Helping the system administrator to locate the source of system failure from complex system architecture,we can improve the reliability of information system in power grid corporation.【Methods】The configuration management database（CMDB）is combined with the fault tree analysis method to analyze the fault rules,and then the relationship between the faulty devices is determined by the CMDB.Finally the fault location is achieved and the instance is verified by monitoring warnings and fault analysis.【Results】This method can effectively sort out the relationship between the functional components and fault representation of the information system.We apply it in the core information system of Power Grid Corp.【Conclusion】The fault location can be done in a short time,which can effectively improve the system’s availability and operating efficiency.
