Oracle HTTP Server Monitoring

Overview

Oracle HTTP Server is a reliable and secure web server based on Apache HTTP Server. It is designed in a way to provide the user with a highly scalable platform for hosting web applications. Oracle HTTP Server can either be used as a Standalone server, or as a web server component for Fusion Middleware cover operating under WebLogic servers domain. Applications Manager's Oracle HTTP Server monitoring capabilities offer complete visibility into the performance of your Oracle HTTP Servers. It helps you to track various key metrics such as response time, cache usage, server utilization rates etc.

To create an Oracle HTTP monitor, follow the steps given below:

  1. Click on the New Monitor link. Choose Oracle HTTP Server from the Web Server/Services category.
  2. Specify the Display Name of the Oracle HTTP server.
  3. Enter the Host Name/IP Address of the host where Oracle HTTP Server is running.
  4. Provide the Port in which the Oracle HTTP Server is running. Default port number is 80.
  5. Enter the Username and Password if Authentication is enabled, else select the required credentials from the Credential Manager list after enabling the Select from credential list option.
  6. Check the SSL is enabled box if SSL is required for connecting to Oracle HTTP server.
  7. Check the Modify Server Status URL box if there is a need to modify the Server Status URL to connect to the Oracle HTTP Server. Upon enabling this option, you can modify the url using the Server Status URL option (Default value: /server-status?auto).
  8. Specify the Timeout value in seconds. Default value is 40 seconds.
  9. Enter the Polling Interval time in minutes.
  10. Choose the Monitor Group from the combo box with which you want to associate Oracle HTTP Monitor (optional). You can choose multiple groups to associate your monitor with.
  11. Click Add Monitor(s). This discovers the Oracle HTTP server from the network and starts monitoring them.
Note:
  • Security/Firewall Requirements: The Oracle 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.
