How to get AssetName by ChannelName (ChannelRecord) [message #1832789]

Hi all,

I have created a bundle that iterates over all assets and channels using AssetService and starts the listeners for all channels. This bundle should handle all events of the channels.
When an event is triggered (onChannelEvent(ChannelEvenet event)), I only get the channel configuration from the ChannelRecord, but I also need information about the AssetName and DriverName. Does Kura offer a function to find out the AssetName based on the ChannelName?

Hi,
we don't have such feature at the moment. You have to track it when you proceed registering the listener.

Best regards

Thanks for your reply. When i activate the listener for a channel in the Kura UI, and wire it with the H2DBStore, how does kura handle this? The assetName is stored in the database. Is it a internal function?

The message coming out of the asset contains also a reference to the name of the asset itself. That is the reason why you are seeing it in the downstream database

Another idea: If I activate the listener via the Ui and connect the assets with the WireGraph to the MQTT-publisher, will there be any information about the asset?

The information will be in the message in the wires. Then it depends on the publisher that you'll use.

The asset name is the same as kura.service.pid. So I used the method assetService.getAssetPid(Asset) and got the asset name! This was my solution to my question.
