Metrics in Flink UI
Hi,
I'm running a job on a local flink cluster but metrics are showing as Bytes
received,records received,bytes sent,backpressure all 0 in the flink UI
even though I'm receiving data in the sink.
Do I need to additionally configure something to see these metrics work in
real time?

Hi Zain
Do you have only one operator or all of the operators are chained together? Maybe you can break the operator chain and check it out.

Hi, if the operator is a source, the amount of bytes received is 0. And if the operator is a sink, the amount of bytes sent is 0.
In your job, the source operator and sink operator is chained as one, so the amounts of bytes received and sent are all 0.
You can archive more details if you set the config with "pipeline.operator-chaining" in Flink SQL or use "StreamExecutionEnvironment.disableOperatorChaining() " in Datastream api.
