Global latency metrics

Hi All,

Is there a method to get the global latency directly? Since I only find the
latency for each operator in the Flink Rest API.

Best,

Shimin

Hi shimin,

For some scenario, your requirement is necessary. And sometimes, we want to
know the total throughput, latency and the event processing rate
end-to-end. But currently, Flink can not support the global metrics.

To Chesnay,

I think it's a good feature the community can consider.

Thanks, vino.

No, you can only get the latency for each operator.

For starters, how would a global latency even account for multiple 
sources/sink?
