Forwarders
Forwarders can stream points and processed events to
sinks
.
The configuration of the forwarders determines which data to forward, along with possible extra forwarder specific settings for the sink.
To create a forwarder:
- navigate to
configuration>forwarders - click
Create forwarderin the top-right corner
This will take you to a screen to configure a new forwarder.
- Enter a unique name
- Optionally enter a description
- Enable/disable the forwarder
- Select a sink type

Event Publishing
Events are published once once they get the state Processed.
When configuring the event publishing, you can specify the MQTT topic where these events will be sent. The topic can be customized using template variables to dynamically generate the topic name based on the event data. This allows for more flexible and organized event management.
For example, you might use a topic structure like events/{assetId}/{eventType} to categorize events by asset and type, making it easier to subscribe to specific types of events in your MQTT client.
Additionally, you can control which events are forwarded by selecting specific assets or event types, providing fine-grained control over the event data that is published.
