Hi Kalyan,
Streaming tab on StreamAnalytix web application is intentionally disabled. But if you want to view it, then you can go to "Data Pipeline" page. There you can see pipelines tiles. You can click on the 'i' icon of the running pipeline tile. It will flip and show "Application URL" link. Hit that link, which will redirect you to Spark UI, where you can see its Streaming tab. Also attached screen shots
