See active connection on apache web server

Question

I need a command or something to see live web viewer in Apache2 web server, in other word i want see the ip address of active connection and i found some commands like :

netstat -plan|grep :80|awk {'print $5'}|cut -d: -f 1|sort|uniq -c|sort -nk 1

netstat -plan|grep :80 | wc -l

netstat -an | grep ESTABLISHED | awk '{print $5}' | awk -F: '{print $1}' | sort | uniq -c | awk '{ printf("%s\t%s\t",$2,$1) ; for (i = 0; i < $1; i++) {printf("*")}; print "" }'

But i can't understand it completely . My questions are :

1 - Is there any other command to server this purpose ?

2 - What is the the state of live visitors in netstat (Establish or Connected) ?

Answer 1

Check out Apache mod_status, this gives an overview of activity at the HTTP level and might be what you're looking for.

Sample output of mod_status

Answer 2

TCP sessions with respect to HTTP are very short lived. Unless I'm viewing a large file, the TCP sessions change to FIN_WAIT_2 and TIME_WAIT within 5 or 10 seconds, so for stateful HTTP connections, web server utilities such as mod_status and apachectl will need to be used. In other words, there isn't a relationship between TCP session state, and an HTTP session state.

1. I think for seeing current ip connectivity only this is the command there . You can refer this for advacned usage http://www.thegeekstuff.com/2010/03/netstat-command-examples/

2. It shows all type of connections time_out , Time_wait , and connected and established in state .

For the above commands, you can do google
