Re: KafkaSource metrics
Hi Ardhani, Thanks for your kindly reply. Our team use your provided metrics before, but the metrics disappear after migrate to new KafkaSource. We initialize KafkaSource in following code. ``` val consumer: KafkaSource[T] = KafkaSource.builder() .setProperties(properties) .setTopics(topic) .setValueOnlyDeserializer(deserializer) .setStartingOffsets(OffsetsInitializer.committedOffsets(OffsetResetStrategy.LATEST)) .build() env .fromSource(consumer, WatermarkStrategy.noWatermarks(), uid) .setParallelism(math.min(parallelism, env.getParallelism)) .setMaxParallelism(parallelism) .name(uid).uid(uid) .rebalance ``` Oscar Ardhani Narasimha 於 2021年5月25日 週二 上午12:08寫道: > Use below respectively > > flink_taskmanager_job_task_operator_KafkaConsumer_bytes_consumed_rate - > Consumer rate > flink_taskmanager_job_task_operator_KafkaConsumer_records_lag_max - > Consumer lag > flink_taskmanager_job_task_operator_KafkaConsumer_commit_latency_max - > commit latency > > unsure if reactive mode makes any difference. > On Mon, May 24, 2021 at 7:44 PM 陳樺威 wrote: > >> Hello, >> >> Our team tries to test reactive mode and replace FlinkKafkaConsumer with >> the new KafkaSource. >> But we can’t find the KafkaSource metrics list.

Re: KafkaSource metrics
Hi Oscar, Thanks for raising this problem! Currently metrics of KafkaConsumer are not registered in Flink as in FlinkKafkaConsumer. A ticket has been created on JIRA, and hopefully we can fix it in next release. https://issues.apache.org/jira/browse/FLINK-22766 -- Best Regards, Qingsheng Ren Email: renqs...@gmail.com On May 25, 2021, 2:35 PM +0800, 陳樺威 , wrote: > Hi Ardhani, > > Thanks for your kindly reply. > > Our team use your provided metrics before, but the metrics disappear after > migrate to new KafkaSource. > > We initialize KafkaSource in following code. > ``` val consumer: KafkaSource[T] = KafkaSource.builder() .setProperties(properties) .setTopics(topic) .setValueOnlyDeserializer(deserializer) .setStartingOffsets(OffsetsInitializer.committedOffsets(OffsetResetStrategy.LATEST)) .build() env .fromSource(consumer, WatermarkStrategy.noWatermarks(), uid) .setParallelism(math.min(parallelism, env.getParallelism)) .setMaxParallelism(parallelism) .name(uid).uid(uid) .rebalance > ``` > > Oscar > Ardhani Narasimha 於 2021年5月25日 週二 上午12:08寫道: > Use below respectively > > flink_taskmanager_job_task_operator_KafkaConsumer_bytes_consumed_rate - > Consumer rate > flink_taskmanager_job_task_operator_KafkaConsumer_records_lag_max - Consumer > lag > flink_taskmanager_job_task_operator_KafkaConsumer_commit_latency_max - commit > latency > > unsure if reactive mode makes any difference. > > On Mon, May 24, 2021 at 7:44 PM 陳樺威 wrote: > > > Hello, > > > > > > Our team tries to test reactive mode and replace FlinkKafkaConsumer with > > > the new KafkaSource. > > > But we can’t find the KafkaSource metrics list.

Re: KafkaSource metrics
Looks like when KafkaSource is used instead of FlinkKafkaConsumer, metrics listed below are not available. Bug? Work in progress?
