    第一步:首先我们需要强大的SNMP信息收集和整理工具,网络中这类工具比较多,如果我们只是监控的话建议使用小巧的monomon即可,当然如果企业内部要自定义建立流量监控站点或服务中心的话可以使用其他支持SNMP的MRTG,PRTG等工具。我们可以到http://monomom.matf.de/download.php地址下载该程序,整个程序只有一个文件(Step one: First of all, we need strong SNMP information to collect and organize tools, network tools such as more, if we only recommend the use of surveillance, then compact monomon can, of course, if the custom-house to set up traffic monitoring site or service center If you can use other support SNMP-MRTG, PRTG, such as instrument. We can http://monomom.matf.de/download.php address to download the program, the whole process only one document)
