IBM HTTP Server Monitoring
Overview
IBM HTTP Server is a web server designed to provide a highly scalable and secure platform for hosting web applications. It is often used with other IBM middleware products like WebSphere Application Server and WebSphere Portal. The server is split into modules, each providing a specific function or feature. The modules can be added or removed from the server configuration, allowing for greater flexibility and customization.

To create an IBM HTTP monitor, follow the steps given below:
- Click on the New Monitor link. Select the IBM HTTP Server under the Web Server/Services category.
- Specify the Display Name of the IBM HTTP server.
- Enter the Host Name/IP Address of the server where IBM HTTP Server is running.
- Provide the running Port number of the IBM HTTP server. Default port number is 80.
- Enter the Username and Password if is Authentication is enabled, else select the required credentials from the Credential Manager list after enabling the Select from credential list option.
- Check the SSL is enabled box if SSL is enabled in the IBM HTTP server.
- Ckeck the Modify Server Status URL box if there is a need to modify the Server Status URL to connect to the IBM HTTP Server. Upon enabling this option, you can modify the url using the Server Status URL option (Default value: /server-status?auto).
- Specify the Timeout value in seconds. Default timeout value is 40 seconds.
- Specify the Polling Interval time in minutes.
- Choose the Monitor Group from the combo box with which you want to associate IBM HTTP Monitor (optional). You can choose multiple groups to associate your monitor with.
- Click Add Monitor(s). This discovers the IBM HTTP server from the network and starts monitoring them.
Note:- Security/Firewall Requirements: The IBM HTTP server host and port should be accessible from the Applications manager installed machine.
- User Privilege: The required user credentials must be provided.
Monitored Parameters
- Availability tab gives the Availability history for the past 24 hours or 30 days.
- Performance tab gives the Health Status and events for the past 24 hours or 30 days.
- List view enables you to perform bulk admin configurations.
