As we all know, there are many factors that affect the network, including latency, conflict, and blocking. Next, let's take a look at the specific Network situation under Linux performance monitoring, and add some of our previous articles. We hope to provide more help to you in terms of

different IP address to run multiple httpd servers, it is necessary to use virtual address, so that the same IP address, if you open two httpd server, you want to specify the port number.Virtual network interface refers to a network interface to specify multiple IP addresses, the virtual interface is such eth0:0, Eth0:1, Eth0:2 ... eth1n. Of course you specify multiple IP addresses for eth1, i.e. eth1:0, e

would like to see the system process accounted for 20% or 30%, user processes accounted for 70% or 80%.If the%usr>80 for a long time indicates that CPU resources are basically consumed by user processes, there is a noticeable bottleneck in the CPU.If the%USR value is rarely >80, the system's possible bottlenecks exist in the middle of the CPU, memory, or I/O.If the%wio value is >15, this is a signal that the disk has a bottleneck.Eight,netstat – Network
