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.
