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.

  8. Specify the Timeout value in seconds. Default timeout value is 40 seconds.
  9. Specify the Polling Interval time in minutes.
  10. 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.
