Streams

In Usage Engine, streams are created inside solutions. Once inside a solution, you can create a new stream. However, you can also import a stream using the JSON schema or simply drag and drop your JSON file. There are example streams curated by the team for you to import and start exploring Usage Engine.  In the following image, each row depicts a stream.

You can also click on Import Stream to open the stream import dialog box. Here, streams can be imported either by dragging a JSON file onto the upper part of the modal. The stream export file contents can alternatively be pasted in the input box. Click on the Import button to confirm the stream entry and add the stream. 

Clicking Create Stream takes you to the Stream Editor where you can create the stream of your choice using the Functions that are part of your subscription package. 

All streams you create in that solution are listed in a table. If you have several streams in the solution, you can search for streams, and by selecting the streams in the table, you can manage them using actions and create Stream Groups. 

Action Toolbar

Selecting a single stream enables the following actions for that stream. You can access the same options using the More menu that is available under the Actions column.

The following actions are available for a stream: 

Action	Action Toolbar Icon	Description
Start		Starts the selected stream.
Schedule		Shows the Schedule Settings dialog box.  Different scheduling options are available from this dialog box. Using one of the buttons the users can designate the desired frequency: Minute, Hour, Day, Week, and Month.  For each option, different scheduling rules can be selected:  Minute  – Run every 15, 20, or 30 minutes.  Hour – Run every 1 hour, 2 hours, 3 hours, 4 hours, 6 hours, or 12 hours.  Day – This option works by designating both a Start Time and defining the Timezone. Additional schedule rules can be added by clicking on the Add time button.  Week – The scheduling rules are defined by choosing the selected days of the week, the start time, and the timezone. Additional times can be entered by clicking on the Add time button.  Month – This is the most complex scheduling option. The scheduling rules allow for select days of the month to be entered in the designated field, the associated start time is entered below it, and the associated timezone is to be selected on the right.
Audit		This opens the Audit Dashboard.
Log		This opens the Logs screen.
Data Correction	—	This opens the Data Correction tab showing errors for the current stream.
Set Notifications		This opens the notifications screen. From here email notification options can be designated for each Notification Group. The following options can be toggled as needed:  Send an email when no file is found Send an email when the stream fails  Send an email when a stream executes successfully Send an email when there is a new error in Data Correction. Click on the Apply button to confirm the notifications setup and close the window.
Export		This will open up the Export Stream modal used to copy down the content of the given stream.  You can either copy the contents using the Copy to Clipboard button or download the stream content in a JSON file format.
Duplicate		This creates a copy of the selected stream. The duplicate will have "Copy" in its title to differentiate it from the original.
Delete		This will delete the selected stream.

Selecting two or more streams removes the actions mentioned above and gives you the choice to delete the streams together or create a stream group.
