You can use SAP Monitoring service for SAP BTP to receive states and metrics of Java applications and the applications' processes. These Java applications can be in different subaccounts or even on different regions. For more information about the currently supported regions and their hosts, see Regions and Hosts Available for the Neo Environment.
The only requirement for this scenario to work is that your user is a member of the subaccounts the Java applications are located in. For more information about how to check subaccount memberships, see Managing Member Authorizations in the Neo Environment.
The communication between your dashboard application and SAP Monitoring service works as follows:
-
An operator accesses a dashboard application in the web browser.
-
The dashboard application requests metrics of a Java application from SAP Monitoring service with a REST API call. For more information about the REST call, see Metrics API.
-
The monitoring service sends back a JSON response with a status code 200 OK. The response contains the state and metrics of the requested application.
-
The dashboard application parses the JSON response and places the metrics in a list.
-
The dashboard application requests the metrics of other Java applications by repeating steps 1 to 5.
-
The dashboard application's UI uses the list with metrics to display those metrics in the browser.
This cloud-metrics-dashboard application is implemented to retrieve the state of two Java applications and the state and metrics of all the processes running on the two Java applications. However, you can change or extend this dashboard application to match your scenario.
