You can check if epel-release is installed on CentOS by running the following command in the terminal:
rpm -qa | grep epel-release
This will check if the epel-release package is installed and will display the package name if it is installed. If the package is not installed, there will be no output.
Once installed you can use
apachetop with the default apche log file and show the last 30secs requests
If you need to choose a different log file or time
apachetop -T 60 -f /var/log/httpd/access_log
This is show data from the log access_log for last 60secs
Use the d key to switch between urls, referrers and hosts
up/down/left/right to show details of each request
