Azure Stream Analytics is the ideal tool for processing data exported from Application Insights. You can input your data from your event hubs or blob storage into Azure Stream Analytics to transform and filter the data and then route it to various sinks. 

For event hub, you can configure your Azure Stream Analytics job to read from the event hub resource that you are exporting the data to from Application Insights just like another event hub input adapter.

For blob, Azure Stream Analytics allows you to configure your AppInsights input with a pre-defined path pattern that Application Insights uses to write to blob storage in the Azure Portal.
