Subject [jira] [Commented] (KAFKA-6040) Expose topic size for monitoring
Date Tue, 10 Oct 2017 09:11:00 GMT

    [ https://issues.apache.org/jira/browse/KAFKA-6040?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16198397#comment-16198397

Ismael Juma commented on KAFKA-6040:

Retention is done on a partition, not topic, so the broker doesn't need to maintain a topic
size at the moment. The partition size is exposed via a Log size metric

>          Issue Type: New Feature
>            Reporter: Michael Andre Pearce
> Currently it seems there is no monitoring endpoint of topic size, even though the cluster
must calculate such estimation to maintain retention.size
> This is useful operationally to get understanding of actual topic usages, based on what
the broker believes.
> As interim it seems some scripts exist to get this, but it would be ideal to get the
value the broker believes/calculates.
