To create an Apache monitor, follow the steps given below:

Click on New Monitor link. Choose Apache Server.
Enter the hostname or IP Address (IPv4/IPv6) of the host in which the monitor is running.
Enter the Subnet Maskof the network.
Provide the port number in which the monitor is running.
Choose SSL option, if SSL is enabled in Apache Server.
Enter the polling interval time in minutes.
If you are adding a new monitor from a Central Server, select a Probe Server.
Enter the Apache User Name and Password if the Apache Server is authenticated.
Modify the Apache Server Status URL if required. The default Server Status URL through which the data transfer details, access details, etc., are collected is http://<host-name:portNumber>server-status?auto. You can now modify the server status URL using this option, if the server status URL is different.
Choose the Monitor Group from the combo box with which you want to associate Apache Monitor (optional). You can choose multiple groups to associate your monitor.
Click Add Monitor(s). This discovers the Apache from the network and starts monitoring them.

Note:

Security/Firewall Requirements: The Apache server host and port should be accessible from the Applications manager installed machine.
User Privilege: The required user credentials should be provided.
