JDBCAppendTableSink Metric

I need to monitor the latency and other similar metric for the Mysql Sink
that Flink writes to. I'm using  JDBCAppendTableSink. Any way how I can
check these. Thanks!

Hi anil,

It seems that there are no dedicated metrics for jdbc sink.
For latency, Flink allows to track the latency of records traveling through
the system[1].
For other metics, I think you can make use of the system metrics. For
example, the metric of numRecordsInPerSecond[2] may be helpful for you.
If these metrics can not meet your requirements, you can report metrics by
yourself, Flink exposes a metric system that allows gathering and exposing
metrics to external systems[3].

Best, Hequn
