Re: monitoring message latency for flink sql app
Hi, mete. As Feng Jin said, I think you could make use of the metric ` currentEmitEventTimeLag`. Besides that, if you develop your job with the DataStream API, you could add a new operator to handle it by yourself.

Hi Mete You can refer to the metrics provided by the Kafka source connector. https://nightlies.apache.org/flink/flink-docs-release-1.19/docs/connectors/datastream/kafka//#monitoring Best, Feng On Thu, May 16, 2024 at 7:55 PM mete wrote: > Hello, > > For an sql application using kafka as source (and kafka as sink) what > would be the recommended way to monitor for processing delay?

RE: monitoring message latency for flink sql app
Hello mete. I found this SO article https://stackoverflow.com/questions/54293808/measuring-event-time-latency-with-flink-cep If I'm not mistake, you can use Flink metrics system for operators and get time of processing event in operator.

monitoring message latency for flink sql app
Hello, For an sql application using kafka as source (and kafka as sink) what would be the recommended way to monitor for processing delay? For example, i want to be able to alert if the app has a certain delay compared to some event time field in the message. Best, Mete
