I just updated our Flink install from 1.4.0 to 1.4.2, but our Prometheus monitoring is not getting the current Kafka lag.
After updating to 1.4.2 and making the symlink between opt/flink-metrics-prometheus-1.4.2.jar to lib/, I got the metrics back on Prometheus, but the most important one, flink_taskmanager_job_task_operator_records_lag_max is now returning -Inf.
Did I miss something?
