I try integrate flink application metrics with graphite/grafana.
Currently, I have 3 flink application, 2 jobs just consume kafka message and do some business logic, another jobs use flink sql over window with watermark, out of orderness time set to 10 seconds
When I send 3 application metrics to graphite. The previous 2 job shows all metrics with complete curve
but the job with sql and wm’s metrics show in UI is on and off
Has anyone ever met this issue?
