Monitoring Kafka

[lirop kaykov]

Hi, I have a question about monitoring kafka.
When using jmx exporter and kafka exporter, you get key metrics like topic
metrics (bytes in per second, messages in per second etc).
Is there a way to get bytes/messages per second per message key?
Meaning, getting the distribution of messages by key.
If not, what is the best way to know how many messages with a specific key
got inside a topic?
