how to check current apache connections
Since apache will spawn a new process for each new connection you need to determine how many httpd processes are currently running
I would recommend checking the count from this command against the MaxClients setting in apache’s httpd.conf:
ps aux | grep -c httpd
To show the number of established connections using apache:
netstat -plnant | grep "httpd" | grep -ic established
Here’s something you can add to your .bashrc to make this easier:
alias connections='echo "processes: "; ps aux | grep -c httpd; echo "Established httpd connections: "; netstat -plnant | grep "httpd" | grep -ic established'
