None

No metrics are published.

Memory

Metrics are published to a queue in memory.

File

Metrics are published to a file on disk located in the AppData/Metrics/  folder (i.e., c:\streamsserverdata\Metrics).

 

To add other Kafka publishers in the drop-down list, ensure their configuration file are available in the AppData/Metrics/Config  folder.

The ID of the new configuration files are displayed in the Publisher drop-down list.

 

Selecting any of these specific Kafka data sources means that this is only place where metrics will be published to.
