Re: Java API to read metrics via JMX

Its actually quite simple, unfortunately you have to read, and then write to TSDB.Enclosed is an example doing this and dumping to InfluxDB JMXCollector.scala Description: Binary data Boris LublinskyFDP Architectboris.lublin...@lightbend.comhttps://www.lightbend.com/ On Aug 8, 2018, at 8:46

Java API to read metrics via JMX

Hi Is there any Java API available so that I can enable our Kafka cluster's JMX port, and consume metrics via JMX api, and dump to a time series database. I checked out jmxtrans, but currently it does not dump to TSDB (time series database). Thanks. R

Re: python-kafka does not work

Do you use auto commit or you commit messages directly? Do you have another node in the same consumer group? On Wed, 8 Aug 2018 at 16:18, 随风 <401580...@qq.com> wrote: > hi，i use python-kafka to consumer message，but a few days later，it is does > not work ，it can not to poll message.i can not deal

Re: Kafka flow

Include Keys in FileStreamSink connector

Hi all, I'm trying to backup the whole content of an avro topic into a file, and later restoring the Kafka topic from the file using Kafka Connect. I'm using avroconverters from both key and value, but key is not included in the dump file. Somebody knows how to include keys using Kafka Connect?
