Show HN: Kafkatop, top-like CLI for Kafka

https://github.com/sivann/kafkatop

Hey HN, for those of you tired of running kafka-consumer-groups.sh and similar tools, here's a small real-time monitoring CLI tool for Apache Kafka, that displays consumer lag and event rates in a clean, top-like interface. You can quickly assess which consumers are lagging and when they will catch up.

I've made this to quickly assess the health of remote on-premises clusters which most of the time lack proper monitoring.

The tool can be found here: https://github.com/sivann/kafkatop

I'd be very interested to hear your feedback or any features you think would add value to this tool!

This is nice. Will you also add the view of topics so I can replace kafdrop?

A better kafdrop and on the terminal... priceless!

Thanks

Thanks! you can list topics and also export ISR per partitions in json with kafkatop. As this is mostly a real-time monitor, what properties of topics would you be interested of monitoring? Would that be ISR % per topic perhaps?
