SAP Business Technology Platform, the in-memory Platform-as-a-Service offering from SAP, enables customers and developers to build, extend, and run applications on SAP HANA in the cloud. It provides access to a development environment in the cloud. The platform includes a comprehensive set of services for integration, enterprise mobility, collaboration, and analytics. 

For SAP Business Technology Platform the following integration scenarios are possible:

The different scenarios contain the following exceptions and point-to-point connections:

1. Integrating SAP Business Technology Platform via SAP Integration Suite - Cloud Integration: 1, 3
2. Integrating SAP Business Technology Platform via SAP Cloud Integration for data services: 1, 2
3. Integrating SAP Business Technology Platform via SAP Cloud Connector Integration: 1, 4 

*) Monitoring content was extended with later support packages (see monitoring template page for details)

The following technical prerequisites have to be met in order to monitor this scenario:

• Monitoring of Java Applications in SAP BTP (Neo): 
  • Is available starting from SAP Solution Manager 7.2 SP03
• Receive alerts from the Alert Notification Service for SAP BTP (Neo and Cloud Foundry):
  • Is available starting from SAP Solution Manager 7.2 SP08
• E2E Application Tracing:
  • Is supported for SAP Business Technology Platform from March 2018 onwards, and requires at least SAP Solution Manager 7.2 SP06

The following SAP Business Technology Platform scenarios are currently covered in public cloud operations with SAP Solution Manager:

• Monitoring of Java application errors in Java application developed on SAP Business Technology Platform in the Neo environment
• Alerts from the Alert Notification Service provided in SAP Business Technology Platform for both the Neo as well as the Cloud Foundry environment
• End-to-End Tracing capabilities for application running in SAP Business Technology Platform in the Neo environment

The collection of exceptions and alert notifications is performed using Exception Management. The metrics to monitor if there were any exceptions or alert notifications are available in a template in Interface and Connection Monitoring.

Monitoring Template: Cloud (SAP BTP) 

Tracing Capabilities

Trace Analysis, also allows you to trace end-user requests having excessive execution times, showing performance metrics, like application response time, interactions between UI and SAP Business Technology Platform, and outbound communications. 

The trace is collected from the backend system(s) as well as from the application running in SAP Business Technology Platform. The SAP passport allows SAP Solution Manager to correlate the related steps over all components and display the complete end-to-end in the End-to-End Trace Analysis application in Root Cause Analysis.

Please note that the SAP backend system and all other systems that are part of the trace must be capable to handle SAP passport. You can find information which system types are supported by E2E Trace Analysis in SAP note 2248724 - Root Cause Analysis in SAP Solution Manager 7.2

For SAP Business Technology Platform currently the following services are enabled for Trace Analysis. 

(*) Due some technical/feature decisions in SAP BTP for Runtime based on Tomcat8, the application developer need to take care for the SAP-PASSPORT update/forwarding by using a specific SapPassportHeaderProvider. You can find more information in the SAP Help documentation.

Preparations in SAP Business Technology Platform (Neo)

The following section described the preparation steps that have to be performed if you run SAP Business Technology Platform in the Neo environment. If you run SAP Business Technology Platform in the Cloud Foundry environment please go to the next section. 

Preparations for Java Application Error Monitoring

Determine Root URL

The API Root URL for SAP Business Technology Platform depends on the host on which your account is hosted on. The host depends on the region as described here:

• SAP Business Technology Platform (SAP BTP) → SAP BTP, Neo Environment → Regions in the Neo Environment → Regions and Hosts Available for the Neo Environment 
• e.g. If your host is us1.hana.ondemand.com, the Root URL to configure is https://publicapingplog.us1.hana.ondemand.com

Create User for Java Log Monitoring

To connect to SAP Business Technology Platform to collect Java application exceptions you need to provide SAP Solution Manager with a user that is allowed to read the default trace.

• The user needs at least the role 'Support User' in SAP Business Technology Platform

Write Java Errors into Default Trace

This last preparation step starts already during the development of the SAP Business Technology Platform application. To be able to collect application errors, these errors must exist in the default trace for the SAP Business Technology Platform java application. Hence developers must write meaningful errors in this trace. The quality of the monitored exceptions completely depends on the quality of the exceptions written by the developer.

• Please see this blog for more information on logging for SAP Business Technology Platform Java applications 

Preparations for Alert Notifications

Enable SAP Business Technology Platform Alert Notifications

Receiving alert notifications is done via the Alert Notification Service which can be enabled for your SAP Business Technology Platform account. 

Important: Please be aware that the use of this service is quota based (billable)!

To enable the service please follow the documentation:

• SAP Alert Notification service for SAP BTP → SAP Alert Notification service for SAP BTP, Neo Environment → Initial Setup

Gather Connection Information

To authenticate towards the service you have to create an OAuth client in SAP Business Technology Platform. Information how to do this you find here:

• SAP Alert Notification service for SAP BTP → SAP Alert Notification service for SAP BTP, Neo Environment → Administration → Credential Management

Please make sure to note down or copy the client secret, as it cannot be retrieved later on. 

You will need the following connection information to connect SAP Solution Manager.

1. In your Subaccount navigate to Services → Alert Notification → Security
2. Root URL: Use 'Consume Events' URL under Endpoints (up to .com)
3. OAuth URL: Use 'OAuth Token' under Endpoints (up to .com)
4. Client ID: Use 'Client ID' of the created OAuth client
5. Client Secret: Use client secret noted down during client creation

Import the SSL certificate for Cloud Foundry

Even if used in the SAP Business Technology Platform (Neo) the alert notification service technically runs in SAP Business Technology Platform (Cloud Foundry). To make sure that SAP Solution Manager can receive alert notifications successfully, you have to import the SSL certificate for Cloud Foundry additionally to the SSL certificate for Neo.

Preparations for E2E Application Tracing

Enable Automatic Trace Upload for SAPUI5 applications

You can enable the automatic upload of the client side trace data, which starts in the background when a trace is ended. Therefore, perform the following steps in your WebIDE or development platform for the SAPUI5 applications in focus.

Note: This operation has to be repeated for each relevant SAPUI5 application.

1. Load the SAPUI5 application in your WebIDE
2. Open the file: neo-app.json
3. Edit the file, adding a "routes" record, of type destination, as shown here:
   {
     "welcomeFile": "index.html",
     "routes": [
       {
          ...
       }
       {
           "path": "/sap/bc/sdf/E2E_Trace_upl",
           "target": {
               "type": "destination",
               "name": "solutionmanager",
               "entryPath": "/sap/bc/sdf/E2E_Trace_upl"
           },
           "destination": "SAP SolManUpload"
       }
     ]
   }
   
4. Save the file
5. Also maintain the above mentioned destination, within SAP Business Technology Platform and SAP Cloud Connector, specifying the SAP Solution Manager relevant gateway host and port.
6. Finally, deploy the SAP UI5 application again to the SAP Business Technology Platform 

Preparations in SAP Business Technology Platform (Cloud Foundry)

The following section described the preparation steps that have to be performed if you run SAP Business Technology Platform in the Cloud Foundry environment.

Preparations for Alert Notifications

   • User: Client ID
   • Password: Client secret
   • If necessary add proxy information to connect to SAP Business Technology Platform 

Step 1: Configure Exception Management

After the basic configuration you now have to configure Exception Management, as the exceptions collected via Exception Management and stored in the central exception store are the basis for the Integration Monitoring data collection.

Configuration for SAP Business Technology Platform Java Applications

This exception store will only exist if SAP Business Technology Platform runs in the Neo environment! 

To access the Exception Management setup please go to transaction SOLMAN_SETUP → Application Operations → Exception Management 

1. In the step 'Define Scope' select the tab 'Cloud Services' and your SAP BTP system. If you didn't configure the system before make sure to select 'All Cloud Services' in the view drop-down. Click on 'Configure' or click 'Next' two times. You will enter the step 'Exception Configuration'.
2. Click 'Add / Configure Log Store'. Select 'SAP BTP Java Application Logs'. Select the end-point you created for Application Exceptions.
3. Select the fields for filtering for your log store. Which fields are filled and what their content is, is determined by the developer of an application (it is somewhat comparable to the Application Log in ABAP). 
   The following filter fields are available:
   • application: Application Name
   • logger: This field usually contains the area and the application name to identify the origin of the logged problem. Supports wildcards (e.g. com.sap*)
   • message: Error text of the exception. Supports wildcards (e.g. Failed*cache)
   • passportId: The SAP Passport of the exceptions
   • severity: Comma separated list of the severity of the exceptions (e.g. ERROR, FATAL)
   • tenant: The account or sub-account ID for the exception
   • user: The user who triggered the exception
4. Maintain the filter values for the fields in the Filter Definition panel under the log stores table. You can also add, remove or change filter fields and values later on in the area. You can use different operators for your filter value. You can add more than one filter filed combination per log store. To add an additional filter field combination click on the button 'Add Filter' in the 'Configured Log Stores' panel.
5. You should not set up the monitoring for the exceptions in the Exception Management. If you activate the monitoring here, you will receive an alert (and if set up this way an email) for every single exception in the application log. Instead we will use Interface and Connection Monitoring to monitor the central exceptions store for exceptions.

Configuration for SAP Business Technology Platform Alert Notifications

To access the Exception Management setup please go to transaction SOLMAN_SETUP → Application Operations → Exception Management 

1. In the step 'Define Scope' select the tab 'Cloud Services' and your SAP BTP system. If you didn't configure the system before make sure to select 'All Cloud Services' in the view drop-down. Click on 'Configure' or click 'Next' two times. You will enter the step 'Exception Configuration'.
2. Click 'Add / Configure Log Store'. Select 'SAP BTP Alert Notifications'. Select the end-point you created for Alert Notification Service.
3. Select the fields for filtering for your log store.  
   The following filter fields are available:
   • category: ALERT
   • eventType: Event type of the alert (e.g. AverageResponseTime)
   • resourceName: The name of the source
   • severity: ERROR or WARNING
   • subject: <tags.monitoring:type> followed by the human readable form of the eventType property. (e.g. [PROBLEM]: OS MemoryUsage)
4. Maintain the filter values for the fields in the Filter Definition panel under the log stores table. You can also add, remove or change filter fields and values later on in the area. You can use different operators for your filter value. You can add more than one filter filed combination per log store. To add an additional filter field combination click on the button 'Add Filter' in the 'Configured Log Stores' panel.
5. You should not set up the monitoring for the exceptions in the Exception Management. If you activate the monitoring here, you will receive an alert (and if set up this way an email) for every single exception in the application log. Instead we will use Interface and Connection Monitoring to monitor the central exceptions store for exceptions. 

Step 2: Configure Interface and Connection Monitoring

The last step is the configuration of Interface and Connection Monitoring. The Interface and Connection Monitoring setup can be accessed via SAP Solution Manager Configuration (SOLMAN_SETUP).
