Learn about the known issues in Streams Messaging Manager (SMM), the impact or changes to the functionality, and the workaround.

CDPD-17361: Consumer Group metrics does not appear in SMM

SMM emits consumer metrics to Cloudera Manager and reads the consumer metrics back from Cloudera Manager. For SMM to work correctly, you must configure the Cloudera Manager Service Monitor Host property. This property is also know as cm.metrics.service.monitor.host.

To resolve:

1. Go to the Configuration tab for SMM.
2. Search for cm.metrics.service.monitor.host.

   

3. In the Cloudera Manager Service Monitor Host field, specify the host name of the Service Monitor host.
4. Save the update.

CDPD-19495: SMM UI does not show producer data on topics page

In the SMM UI, the topics page, the topic profile pages, and the broker profile pages consistently show 0 for producer messages.

Workaround: For the real producer metrics, please check the aggregated REST API responses. The real producer metrics are within the producerIdToOutMessagesCount field.
