Netstat-n|grep 80 A large number of time_wait

Running the Netstat-n|grep 80 | awk '/^tcp/{++s[$NF]} END {for (A-in S) print A, S[a]} ' was found to have a large number of time_wait, which would require viewing the interface log for blocking behavior, or modify the Linux configuration to reduce its time_ Wait value.

The number of server visitors can be by command: netstat-pnt | grep:80 list, such as the request server on the previous page, through the command to view the results, the following established indicates that the server is being accessed, you can add wc-l statistics by the number , the final command is: netstat-pnt | grep:80 | wc-l This command can count the number of server all URLs requested
