13 -Create within your flow an XSLT extension gateway setup as depicted above. The linking of the XSLT transformer to the XSLT extension gateway can be skipped in the exercise.
14 +Navigate to Manage -> Monitoring -> Event Streaming Statistics for the model you selected to execute this exercise. Here, analyze the partition size and consumer lag on at least one topic.

16 +{{info}}Given that the implementation of the prerequisites can differ, the results of what you see can also differ. We use example data that is part of our Sales Demo model to feed the Vehicle Event topic. An event processor subsequently determines whether a vehicle alert needs to be generated based on the type of event. This accounts for the difference in partition size between both topics. An event processor is a consumer group, and due to the high volume of messages placed on the Vehicle Event topic, we see that a consumer lag is reported.{{/info}}
