How can I check how much disk space is being used by Kafka

My disk space is running out, after syncing 2 millions message in one of my Kafka topic. I even deleted the topic but still the space is somehow seems consumed. Any help of link would be appreciated.

How much space does Kafka use?

Furthermore, Kafka uses heap space very carefully and does not require setting heap sizes more than 6 GB. This will result in a file system cache of up to 28-30 GB on a 32 GB machine. You need sufficient memory to buffer active readers and writers.

Does Kafka use disk?

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.

What happens if Kafka partition is full?

Often the data will stay there and get deleted once a specified retention period or max size/data limit has been reached.

Use the below command to know how much disk space consumed by each topic

du -sh /tmp/kafka-logs/*

Another way to determine the size of the topic to send metrics, such as graphite. Then the size can be found as follows: kafka.log.Log.<topic_name>-<partition_number>-Size.value
