请教大家一个路由器CPU飙高的问题:
内网采用PRTG收集流量,在每天上班开始的10-15分钟内,其中一台接用户数比较多的路由器,CPU会飙到99%,这时PRTG服务器就连接不上路由器因此红色报警。在CPU飙升至99%时,IP Input 和IP NAT Ager 两个进程使用率比较高,但也只是20-30%左右,没有网上故障案例中的90%以上。
我想了解下114个CPU进程的是对应的是什么作用?大家是否有这方面的文档介绍?以及路由器CPU飙高的原因?
1、路由器的型号为
cisco RSP4+ (R5000) processor with 262144K/2072K bytes of memory.
R5000 CPU at 200Mhz, Implementation 35, Rev 2.1, 512KB L2 Cache
路由器下有700个用户使用。
2、下面显示的不是99%的情况
