  • Configure and deploy your IoT or machine learning models on the SAP Leonardo platform as required for integration with Grafana.

    •  

  • Generate the necessary API keys for accessing SAP Leonardo services.

 

Install Grafana

 

  • Download and install Grafana using a package manager or the official Grafana website.

    •  

  • Start the Grafana server using the following command:

 

systemctl start grafana-server

 

  • Ensure Grafana starts automatically at boot by enabling it:

 

systemctl enable grafana-server

 

Configure SAP Leonardo Data Source in Grafana

 

  • Log in to your Grafana dashboard using your browser. The default URL is usually http://localhost:3000.

    •  

  • Navigate to the 'Data Sources' section and click on 'Add data source'.

    •  

  • Choose 'HTTP' as the data source type since SAP Leonardo can expose data through RESTful APIs.

    •  

  • Under the URL section, insert the endpoint URL of your SAP Leonardo API.

    •  

  • Set the authentication type according to your SAP Leonardo setup (e.g., API Key, OAuth, etc.). Enter the required credentials or API key.

 

Create a Dashboard in Grafana

 

  • Start by clicking on the '+' icon on the sidebar and choose 'Dashboard'.

    •  

  • Select 'Add New Panel' to create a new visualization for your SAP Leonardo data.

    •  

  • Choose a suitable visualization type based on the nature of the data (e.g., graph, table, heatmap).

    •  

  • In the Query section, construct a query to fetch the necessary data from SAP Leonardo API. Example:

 

GET /iot/data HTTP/1.1
Host: your-sap-leonardo-api-endpoint
Authorization: Bearer your-api-token

 

  • Use transformation functions provided by Grafana if you need to process data before visualization.

 

Test and Validate Integration

 

  • Review the initial data visualizations on your Grafana dashboard to ensure data is being correctly reflected from SAP Leonardo.

    •  

  • If any data discrepancies or errors are found, recheck connections, API endpoints, and authentication details.

    •  

  • Iterate over dashboard improvements by customizing panels, using different queries, and applying alerts if necessary.

 

Enhance with Advanced Features

 

  • Utilize Grafana's alerting feature to receive notifications based on data thresholds from SAP Leonardo services.

    •  

  • Configure additional data sources, if required, to combine SAP Leonardo data with other sources for a comprehensive dashboard.

    •  

  • Use filters and variables to create dynamic dashboards that are easy to navigate and tailor to different use cases.

Troubleshooting SAP Leonardo and Grafana Integration

How to connect SAP Leonardo data to Grafana?

 

Setup SAP Leonardo Connectivity

 

  • Ensure SAP Leonardo IoT environment is operational and generate API keys for access.

    •  

  • Utilize SAP IoT APIs to fetch data, ensuring endpoint URLs and credentials are correct.

 

Install and Configure a Data Source Plugin in Grafana

 

  • In Grafana, install a generic REST API data source plugin for interfacing with SAP Leonardo.

    •  

  • Navigate to 'Configuration' > 'Data Sources' in Grafana and add a new data source.

 

Fetch Data into Grafana

 

  • Configure the data source with SAP Leonardo IoT API details, setting authentication and necessary headers.

    •  

  • Develop a query to extract data from SAP Leonardo using Grafana’s JSONPath or other query languages.

 

Create a Dashboard

 

  • Use the data source to create panels and visualize IoT data. Adjust variables and queries as needed for real-time insights.

    •  

  • Customize panels to best represent the specific data metrics imported from SAP Leonardo.

 

{
  "api_key": "your_generated_api_key",
  "base_url": "https://your.sap.leonardo.api"
}

 

Why is SAP Leonardo data not appearing in Grafana dashboards?

 

Check Data Source Configuration

 

  • Ensure that the SAP Leonardo data source is correctly configured in Grafana. Verify that the API endpoints, authentication details, and data mapping are properly set up.

    •  

  • Test the connection between Grafana and SAP Leonardo using a test query to confirm connectivity.

 

Verify Data Retrieval

 

  • Check if data is being retrieved from SAP Leonardo into Grafana. You can use Grafana's query inspector to debug data queries and inspect the response from SAP Leonardo.

    •  

  • Use the following command to test data retrieval:

 


curl -X GET "https://leonardo.api.your-instance/sap/data" -H "Authorization: Bearer YOUR_ACCESS_TOKEN"

 

Dashboard Configuration

 

  • Make sure your Grafana panels are configured correctly to display the data. Confirm the correct queries, time range, and visualization settings.

    •  

  • Review any transformations or variables applied to ensure they don't filter out data inadvertently.

How to troubleshoot authentication issues between SAP Leonardo and Grafana?

 

Check Network Connectivity

 

  • Verify network connections between SAP Leonardo and Grafana to ensure endpoints are reachable.

 

Review Authentication Configuration

 

  • Ensure authorization credentials in Grafana and SAP Leonardo match the configurations, such as keys and tokens.
  • Check allowed origins or IPs within SAP Leonardo settings to ensure Grafana addresses are permitted.

 

Verify User Permissions

 

  • Confirm user accounts have appropriate permissions within both systems to establish a secure connection.

 

Logs Analysis

 

  • Analyze SAP Leonardo and Grafana logs for any authentication-related errors or warnings.

 

Test Authentication Manually

 

  • Use curl or Postman to manually test API calls from Grafana to SAP Leonardo to isolate the issue.

 

curl -X GET "https://leonardo_api_endpoint" -H "Authorization: Bearer YOUR_TOKEN"

 

Check System Time Synchronization

 

  • Ensure both systems have synchronized time settings to avoid token expiration or validity issues.
