Chapter 7 Monitor resource details Understanding HTTP monitor resources 664 HTTP monitor resources monitor HTTP services that run on the server. HTTP monitor resources monitor HTTP protocol but they are not intended for monitoring specific applications. HTTP monitor resources monitor various applications that implement HTTP protocol. HTTP monitor resources Note 1 For monitoring target resources, specify service resources or script resources that start HTTP services. Monitoring starts after a target resource is activated. However, if HTTP service cannot be started immediately after the target resource is activated, adjust the time using Wait Time to Start Monitoring. Note 2 HTTP service may produce operation logs for each monitoring operation. Configure HTTP settings if this needs to be adjusted. Monitoring by HTTP monitor resources HTTP monitor resources connect to the HTTP server and execute the command for acquiring HTTP header. As a result of monitoring, the following is considered as an error: (1) When connection to the HTTP service fails. (2) When an error is notified as a response to the command. Displaying and changing the HTTP monitor resource details 1. Click Monitors on the tree view displayed on the left side of the Builder window. 2. List of the monitor resources is displayed in the table view on the right side of the screen. Right click the target HTTP monitor resource, and click the Parameter tab in the Monitor Resource Property window. 3. On the Parameter tab, you can display and/or change the detailed settings by following the description below. ExpressCluster X 2.0 for Windows Reference Guide
