Universal Event Templates
Universal Event Templates
Universal Events are administrator-defined events with administrator-defined attributes.
Universal Events can be defined:
Globally | In a Universal Event Template. |
Locally | As part of a Universal Extension-based Universal Template. |
Note
When publishing Universal Events through the Web Service API or an extension-based Universal Task Publisher, take into consideration both Universal Controller server and Database server sizings.
Global Universal Events
For any global Universal Event, you must define a Universal Event Template for it to allow the event to be monitored by a Universal Monitor.
Local Universal Events
If a Universal Template type is Extension, and the Universal Extension can generate a local Universal Event, you must identify the Event by using the Event Templates tab on the Universal Template Details to allow the event to be monitored by an Universal Monitor.
Global and Local Universal Events
Additionally, Extension-based Universal Templates can publish global Universal Events.
Creating a Universal Event Template
Step 1 | From the Automation Center navigation pane, select Configuration > Universal Event Templates. The Universal Event Templates list displays a list of all existing Universal Event Templates. Below the list, Universal Event Template Details for a new Universal Event Template displays.
|
---|---|
Step 2 | Enter / select Details for a new Universal Event Template, using the field descriptions below as a guide.
To display more of the Details fields on the screen, you can either:
|
Step 3 | Click a button. The task is added to the database, and all buttons and tabs in the Universal Task Details are enabled. |
Note
To open an existing record on the list, either:
- Click a record in the list to display its record Details below the list. (To clear record Details below the list, click the New button that displays above and below the Details.)
- Clicking the Details icon next to a record name in the list, or right-click a record in the list and then click Open in the Action menu that displays, to display a pop-up version of the record Details.
- Right-click a record in the a list, or open a record and right-click in the record Details, and then click Open In Tab in the Action menu that displays, to display the record Details under a new tab on the record list page (see Record Details as Tabs).
Universal Event Template Details
The following Universal Event Template Details is for a new Universal Event Template.
Depending on the values that you enter / select for these fields, more (or less) fields may display. See the field descriptions, below, for a description of all fields that may display in the Universal Event Template Details.
Universal Event Template Details Field Descriptions
The following table describes the fields, buttons, and tabs that display in the Universal Event Template Details.
Field Name | Description |
---|---|
Details | This section contains assorted detailed information about a Universal Event Template. |
Name | Name of this Universal Event. |
Label | User-friendly display name for this event, to be displayed within the client. The Label must be unique for Global Events and unique within Local Events. |
Description | Description of this event. |
Time To Live | Default value for the length of time, in minutes, that the Universal Event data is valid. This value can be unspecified (null). The Time To Live value can be overridden in the published event. If the Time To Live does not exist in the published event, then this value, if defined, will be used. If neither value exists, the Time To Live is 0, which means the event is deleted as soon as it is published. |
Unmapped Attributes Policy | Defines how unmapped/unknown attributes that are in the published event are handled.
|
Attributes | Name, Label, and Type of each attribute.
|
System Event | Indication if this type of event is a System Event. |
Metrics | This section contains information about configuring metrics for a Universal Event Template. To enable OpenTelemetry metrics, you must configure an Open Telemetry metrics exporter in uc.properties , otherwise, a noop meter provider is used. |
Metric Type | Specifies the type of metric to instrument. Options are:
|
Metric Name | Specifies the metric name. The metric name can be a maximum of 63 characters and should be universally unique, for example:
The universal event Description will be used as the metric description. The following namespaces (prefixes) are reserved and cannot be used for user-defined metric names.
|
Metric Value Attribute | Specifies the name of an Integer or Float universal event attribute to use for the metric value when incrementing the counter or recording a histogram value. If left unspecified, a counter will be incremented by 1, and a histogram will record a value of 1, for each published universal event. |
Metric Unit | Specifies an optional unit of measure. Maximum length of 63 ASCII characters. Units should follow the Unified Code for Units of Measure. |
Metric Label Attributes | Specifies a comma-delimited list of universal event attribute names to use for metric labels. For example, At most 8 label attributes can be specified. Do not specify attributes with high cardinality (many different attribute values) or attributes that may contain sensitive information. |
Optional Metric Labels | Specifies which system-supplied metric labels to include.
The Task Name value will be represented by the unresolved task name at launch time to avoid the high cardinality of resolved task instance names. If multiple business services are assigned to the universal event, the Business Services value will be represented as a comma-delimited list of business services in alphabetical order.Be mindful that the Business Services metric label could have high cardinality depending on how you assign business service membership. |
User-Defined Metric Name and Labels
If the OTEL metrics exporter is configured, for each Universal Event Template or Universal Template Event Template with a metrics designation, the following metric will be exported.
Name |
The metric name and labels may differ depending on the metric type and/or any normalization you are using, for example, Prometheus Normalization. |
---|---|
Type | Counter, UpDownCounter, or Histogram |
Description | The metric description is inherited from the Universal Event Template or Universal Template Event Template. |

Pre-Defined Global Universal Event
Universal Controller is pre-populated with global Universal Event system templates:
- System Property Changed
- Agent Changed
- Task Status Changed
(System Templates are read-only and cannot be deleted. During a new installation or a maintenance update, System Templates are imported.)
System Property Changed Universal Event
Whenever a Universal Controller system property is updated (from an active or passive node), a UAC - Property Changed Universal Event will be published.
The event attributes are shown below.
Agent Changed Universal Event
A UAC - Agent Changed Universal Event will be published if one of the following conditions is met.
Active - Agent becomes Active.
Decommissioned - Agent gets marked as Decommissioned.
Deleted - Agent is Deleted.
Offline - Agent goes Offline.
Suspended - Agent gets Suspended.
Registered - New Agent is Registered into the system.
Resumed - Agent is Resumed.

The event attributes are shown below.
Task Status Changed Universal Event
A UAC - Task Status Changed Universal Event will be published if the task instance status changes.
The event attributes are shown below.
