i have to create nagios plugin to monitor the apache web server ,particularly the number of active and passive connections from client and number of threads active at any instant. So how can get the needed datas from the apache web server... Suggest me way to get those datas

The following should give you the number of current connections:

netstat -anp | grep httpd | grep -c EST

This should give you the number of threads:

ps aux | grep -v grep | grep -c httpd

what is the difference "LISTEN,SYN_RECV,SYN_SENT,ESTABLISHED,ITMED_WAIT,TIME_WAIT...", "netstat -anp | grep httpd | grep -c EST" is the number of current connections, but I think currnet connections is not the number that how many people access apache same time (simultaneously)" ,if I want to know "how many people access apache on the same time (simultaneously)" , what should I do ?

Apache has it's own status URIs, maybe look into getting info out of those. Even better check the Nagios Plugin Exchange first. Maybe somebody already invented this wheel.
