------------------------------------------
Hi [~lansg], sorry for the slight offtopic question, I am just wondering about
the current relation between Yammer based metrics and Kafka Metrics. We have a
custom {{kafka.metrics.reporter}} integrated at work and recently I faced some
challenges when wanted to collect KRaft related metrics. It turned out those
are contained in Kafka Metrics which require an entirely different reporter
({{{}metrics.reporter{}}}). When I researched the topic I found. [this
answer|https://stackoverflow.com/questions/54401834/difference-between-metric-reporters-and-kafka-metrics-reporters-properties-i]
on SO. The answer is quite old so I am wondering about the current state of
affairs. Are Yammer based metrics considered deprecated? Should any new metrics
be added to exclusively Kafka Metrics? What is the direction set by the Kafka
community? Thanks in advance
