Displays a list of all noteworthy events that have occurred or that are still active.
When placed in a page, you must choose whether to show events that are finished and therefore historical or show events that are still active.
The widget requires the READ_EVENT userās permission, and it is aware of the page context and so can load events over multiple customers, locations, and machines.
Active or Historical Events
By setting the āEvent Statusā widget property, you can select whether active or historical events must be displayed.
If the āEvent Statusā property is left blank, the widget will allow DPS users to switch between active and historical events.
Details Navigation
Clicking on a row opens the event details pop-up. Optionally, the event details can be opened in a full page (see Details Mode option).
The header of the event details popup contains the event name, description, and a breadcrumb that provides the context of the event, and whose tokens can be clicked to quickly jump to related objects (e.g. Customer, Location, Thing).
The event details body is generated through a template, which by default reports the event's main information (e.g. timeline, technical description), but in the alternative, you can redefine the template within the event definition page.
On the event list rows, you can also click directly on specific information to jump to the event-related objects:
Customer Name / Code ā Customer details page
Location name ā Location details page
Thing Name / Serial Number ā Thing details page
In all other cases, the event details pop-up/page is opened.
Search for Events
On the top right part of the widget, a search control bar allows filtering events by a text key.

Optionally, by pressing the Advanced Search icon, a dedicated panel allows the DPS user to specify multiple conditions based on properties.

The provided inputs are preserved during navigation, also across pages in case the same widget āIdā is used.
Optionally, by using the āQueryā property, a set of conditions for pre-filtering events can be defined in the template (e.g. failures only).
In the template, you can specify the āSearch Fieldsā used to filter events by text key.
In case the āQuery Variableā property has been defined (the list is filtered from a Search Field placed in the page), the search control bar is automatically hidden and thus not visible to the user.
The advanced search allows filtering events by:
Text Key: text that is searched in the name, title, and description of each event.
Customer: a customer can be selected, in the case of a user belonging to an organization or partner.
Severity: the severity of the event, one of Failure, Major Anomaly, Minor Anomaly, and Operation.
Period: the time period used to filter events by start timestamp.
Thing Definition or Product Model: one or more thing definitions or product models.
Type: type of event, choosing one or more definitions.
By clicking the Export button, all events that meet the search criteria can be downloaded as a CSV file.
User Reported Events
DPS users can manually report events by clicking on the 3-dots icon and the āReport Eventā action.
A pop-up requests the user to select the event to register, and optionally provide some additional notes for technicians.
