3.5.3 Alive monitoring
With your system operation, you need to consider whether to adopt the alive monitoring mechanism which monitors for a continuous operation of the JP1/DH - Server server. Note the following points when performing alive monitoring:
-
To perform the alive monitoring of JP1/DH - Server over the network, send HTTP GET requests to the login window (https://servername/index.jspx) of JP1/DH - Server at regular intervals, and check for responses. If the system does not respond to successive requests, or if server error responses (HTTP status code 5xx) are continuously returned, contact your operational administrator.
-
Sending an HTTP GET request to the login window of JP1/DH - Server causes access from the web server to the database. Thus, this approach allows you to detect whether the JP1/DH - Server database has a failure or is down.
-
Perform the alive monitoring over the network on a different machine from the JP1/DH - Server machine. Also, use the same network path as the one that users actually use for access to JP1/DH - Server. In this way, you must monitor whether the service is down because of a failure in the network infrastructure or a device before JP1/DH - Server is reached.
