通用型网络交换机监控系统设计与实现

Design and Implementation of General Network Switch Monitoring System

目的:实现医院三大独立局域网多个品牌、多种类型网络交换机的实时性能监控。方法:引用SnmpSharpNet标准动态链接库,利用简单网络管理协议服务,以大量内置对象标识符特征值为参数,定时自动轮询方式采集交换机的多种性能指标信息,通过Web方式展现采集数据并示意警告。结果:轮询周期为60秒,获取CPU利用率、不可达信息、内存利用率和风扇状态共4个关键性能指标的实时数据,监控软件操作简单,在实际网络维护和网络故障排查中起到重要作用。结论:网络交换机监控系统协助网络管理者准确及时发现交换机故障,是一种有效的网络管理工具。

Objective:To realize the real-time performance monitoring of three independent LAN network with multiple brands and types of switches in hospital.Methods:By quoting the standard dynamic link library named SnmpSharpNet and applying simple network management protocol service,multiple performance index information of the switch can be collected in automatic polling mode,with a large number of built-in object identifiers as parameters.The collected data is displayed through the Web with warning.Results:The polling cycle was set to 60 seconds,and the real-time data of 4 key performance indicators were obtained including CPU utilization,unreachable information,memory utilization and fan status.It contains a simple operation in the monitoring software,which plays an important role in the actual network maintenance and network troubleshooting.Conclusion:The network switch monitoring system is an effective network management tool,which helps our network managers to find switch fault precisely and timely.
