+|---|---|---|
+| `ProviderName` | string | The event provider that will produce the specified event. |
+| `EventName` | string | The name of the event, which is a concatenation of the task name and opcode name, if any. The task and opcode names are separated by a '/'. If the event has no opcode, then the event name is just the task name. |
+| `PayloadFilter` | map (of string) | (Optional) A mapping of event payload field names to their expected value. A subset of the payload fields may be specified. |
