Disk Usage

The Disk Usage metric shows the percentage of disk space being used by Kafka. Kafka will gradually use more and more disk space in order to store messages for each topic. The two main aspects of Kafka disk usage are the replication factor of Kafka topics, and the broker log retention settings. While the disk usage of your cluster will be monitored by Instaclustr to ensure your cluster never runs out of disk space, you can reduce overall disk usage by changing the broker log retention settings. See here for more information regarding broker log retention settings and how to change them from the defaults.
