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.  

Preparations in SAP Business Technology Platform (Neo)

The following section describes 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 Business Technology Platform, 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 Focused Run 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 Cloud Platform Alert Notification → SAP Business Technology Platform AlertNotification, 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 Cloud Alert Notification → SAP Business Technology Platform AlertNotification, 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 Focused Run.

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 (full URL)
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 Focused Run can receive alert notifications successfully, you have to import the SSL certificate for Cloud Foundry additionally to the SSL certificate for Neo.

1. In your Subaccount navigate to Services → Alert Notification → Security
   
2. Click on the 'Consume Events' URL under Endpoints to open it in a browser
   
3. Import the SSL certificate for this website into SAP Focused Run STRUST as described above

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": "focusedrun",
               "entryPath": "/sap/bc/sdf/E2E_Trace_upl"
           },
           "destination": "SAP FRunUpload"
       }
     ]
   }
   
4. Save the file
5. Also maintain the above mentioned destination, within SAP Business Technology Platform and SAP Cloud Connector, specifying the gateway host and port used by your app.
   • Essentially you can copy the path for the odata services just replacing the path value.
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

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 Cloud Platform Alert Notification → Administration → 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 Cloud Platform Alert Notification → 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 Focused Run.

1. Select your sub-account and find the Alert Notification Service
2. Navigate to Service Keys → Create Service Key
3. Root URL: Use 'url' value of the service key (up to .com)
4. OAuth URL: Use 'oauth_url' of the service key
5. Client ID: Use 'client_id' of the service key
6. Client Secret: Use 'client_secret' of the service key

Create Custom Alerts

SAP Cloud Foundry doesn't have any available event that come out of the box. Hence to actually receive alerts from application in SAP Cloud Foundry you have to implement the alert creation in your application.

Find more information here:

• SAP Cloud Platform Alert Notification → Integration → Integrating with a Custom Application

Input Values for SAP Business Technology Platform

• Environment: Neo or Cloud Foundry
• Account: Your account ID
• Root Account URL:
  • Cloud Foundry: "url" value of the service key (up to .com)
  • Neo: Use the "Consume Events" field from the Endpoints (up to .com)

If you want to use ANS and Java Logs in Neo, you can use one the root URLs for Neo. The actual distinction happens in the end-point configuration. 

Input Values for SAP Business Technology Platform

For SAP Business Technology Platform the input values for the end-point depend on the environment and the data you want to collect. For SAP Business Technology Platform on Cloud Foundry, only Alert Notification Service events can be collected. For Neo, you can collect ANS events as well as java logs. Since the root URL between ANS and java log differs, you have to create two endpoints if you want to collect both types of data in Neo.

End-point for Cloud Foundry

• Global:
  • API Type: Alert Notifications
  • API Root URL: "url" value of the service key (up to .com)
• Authentication:
  • Type: OAUTH
  • OAuth URL: "oauth_url" of the service key
