4. Agenda Dashboards vs Real-Time (near) Dashboards
Real-Time Dashboards in Power BI
Power BI REST APIs
Using Power BI REST API in your applications
Using streaming data source
Using non-streaming data source

5. Dashboards vs Real-Time Dashboards
Static Dashboard VS

6. Real-Time Monitoring Cases
Fraud detection
Connected car scenario
Click-stream analysis
Financial portfolio alerts
Smart grid
CRM alerting sales with customer scenario
Data and identity protection services
Sales tracking

7. Real-Time Dashboards in Power BI

8. Power BI REST API
Use REST API for pushing data to Power BI from application
Native Client
Web application
Allows to interact and manage almost all Power BI objects
Datasets
Tables
Dashboards
Groups
Allows to create (near) real-time dashboards with automatic update

9. Power BI REST API: Objects Model
/DataSets
GET DataSets - List DataSets
POST DataSet – Create DataSet
POST Table Rows – Add Rows
DELETE Table Rows – Delete Rows
PUT Table – Update Schema
/Groups
GET Groups – List groups
/Reports (Preview)
GET Reports - List reports
/Dashboards (Preview)
GET Dashboards - List dashboards
GET Tiles – list tiles
GET Tile -get tile
Uses Standard technologies
REST
JSON
OAuth
Cross-Platform
Easy to use

10. Power BI REST API: Not supported (not yet)
Push data into existed dataset
Excel, PowerBI Desktop,…
Create relations between tables
Delete range of rows
Delete existed dataset
Get data from existed dataset

11. Demo http://docs.powerbi.apiary.io

12. Power BI REST API: Workflow

13. Power BI REST API: Authentication
Authenticate application in Azure Active Directory using OAuth2
Create a new user account in Azure AD
Add new application on Azure Management Portal
Grant application access to Power BI Service and set permissions
Get Client ID

14. Power BI REST API: Authentication process

15. Power BI REST API: Web authentication process

16. Power BI REST API: Using in application
Authentication in Azure AD
Use Microsoft.IdentityModel.Clients.ActiveDirectory Library
Install from NuGet
Get the token (new or refresh one)
Call REST API method specifying the Bearer token in the header
Receive JSON answer

17. Demo Power BI console app

18. Power BI REST API: Capacity Limits
Max number of rows per one request - 10К
Total number of rows per hour
Power BI free: 10K rows/hour per dataset
Power BI Pro ($9.99): 1М rows/hour per dataset
Max number of rows per table 5М
Depends from retention policy for dataset
None – insert up to limit 5М rows, then error
basicFIFO – insert up to 200К rows and then start deleting old one
Max number of POST requests is 5 per dataset

19. Streaming data: Event Hub & Azure Stream Analytics
Scalable system for processing and visualizing data from devices
Azure Event Hub allows to ingest up to millions events per second
Has own REST API
Azure Stream Analytics allows to run query on top of streaming data.
Like StreamInsight or Apache Storm
Allows to use Event Hub as source
Allows to aggregate data per time periods
Allows to send result to outputs. For example Power BI

20. Demo Azure EventHub & Stream Analytics

21. Non-streaming data sources
Use DirectQuery in Power BI for getting data from
Azure SQL/DW
On-Premise SSAS
Spark on Azure HDInsight
You can’t see dynamic updates on charts, but don’t need refresh data source

22. Summary Real-Time (near) Dashboards on Power BI – it’s possible
Power BI REST API – easy and convenience way to do it
Get data from Native/Web applications and streaming sources
Get data from non-streamed sources
