The Inspect tab in the Data aggregator function allows you to manage individual aggregation sessions, including viewing, inspecting, and deleting them. There are a few ways to access the Inspect tab, via the Data aggregator function as documented below, and via the Aggregation tab, see Aggregation tab for more details.
Note!
The Inspect tab of the Data aggregator function is only accessible after the stream has been executed at least once.
To open the Inspect tab, double-click the Data aggregator function icon from the stream editor canvas, then click on the Inspect tab at the top right of the page.
