There's not currently anything more detaild than what is included in http://kafka.apache.org/documentation/#monitoring There's some work trying to automate the generation of that documentation ( https://issues.apache.org/jira/browse/KAFKA-3480). That combined with some addition to give longer descriptions for metrics could potentially help this situation.
That said, for the example you mentioned, this is just what the description says: when a log segment gets flushed to disk (including the index and time index files), this tracks how long that flush takes. -Ewen On Thu, Jan 5, 2017 at 7:21 AM, Robert Quinlivan <rquinli...@signal.co> wrote: > Hello, > > Are there more detailed descriptions available for the metrics exposed by > Kafka via JMX?
