Logs

Logs allow you to see detailed information about how a stream execution went, search for errors, and form an understanding of the timeline of events. The Logs view provides you with the details of the events generated every time you run a stream.

Note!

There can be some cases where no logs will be displayed, for example, HTTP Functions where only errors will be shown.  

Accessing the Logs view

You can access the Logs view by clicking View logs from the Stream Editor.
