I would like to know how I can start monitoring dead letter Kafka topics. Currently I am using a custom service to identify Kafka listeners. However, I am not able to see any dead letter topics.
I need help/guidance on how I can pull dead letter Kafka topics. Whether it be through custom service or any extension.
Thanks
@victor_balbuena Do you think the new Kafka extension could handle this use case? https://www.dynatrace.com/hub/detail/apache-kafka/#metrics
The new Kafka extension doesn't capture this metric out of the box, but there is a JMX metric under kafka.connect:type=task-error-metrics,connector=*,task=* that have the deadletterqueue-produce-requests attribute, which can be added to a custom-built JMX extension for Kafkfa. This metric refers to the Dead Letter queue though, not the topic. There is no JMX for any Dead Letter topic.
