Hi,
I'm afraid you're correct, this is currently not exposed and you would
have to hack around some things and/or use reflection.
AbstractStreamOperator has a field latencyStats [1], which is what holds
the metrics. This is being updated from method
reportOrUpdateLatencyMarker [2].
I hope that helps somewhat.
Best,
Aljoscha

Hi community,
where from the Dlink code I can get the value of 99th percentile latency
(flink_taskmanager_job_latency_source_id_operator_id_operator_subtask_index_latency{operator_id="93352199ce18d8917f20fdf82cedb1b4",quantile="0.99"})?
Probably I will have to hack the Flink source code to export those values
to my own operator. Nevertheless, it is what I need.
Kind Regards,
Felipe
