Application Streaming
Application Notifiers allow data from an Application’s entire Device population to be securely forwarded to third parties; typically data-processing platforms that provide tailored aggregation, analysis and visualization services. The Notifier configuration provisions the third party’s end-point communication requirements, enabling the Network Server to establish and maintain the northbound data stream.
Note
- Only Application Provider Administrators can create, edit and delete Notifiers.
To add a Notification Target from the Applications view: first select an Application row from the table; next click the "Modify Notification Target" toolbar button; and lastly select "Add Target" from the dropdown menu. Additional options to Edit and Delete will be present for existing Notification Targets.
Each Notification Target type has a set of common configuration options and a set of additional options that are unique to that target. Some target types do not support all of the common options, so these options may not always be visible.
Additionally, Notification Targets may be edited from the Application Details view by clicking the gear icon in the upper right corner of the Application Details Information panel:
Configuration Options
The following options, displayed as checkboxes in the Notification Target configuration dialog, toggle inclusion of the fields shown below in the data streamed to the Notification Target:
| Option | Description |
