Hi there, I have integrated kafka with flink1.5, also with the help of prometheus and Granada to display metrics of flink 1.5, now i get three indicator about latency as below: 1)flink_taskmanager_job_latency_source_id_source_subtask_index_operator_id_operator_subtask_index_latency(short for latency) 2)flink_taskmanager_job_latency_source_id_source_subtask_index_operator_id_operator_subtask_index_latency_count(short for latency_count) 3)flink_taskmanager_job_latency_source_id_source_subtask_index_operator_id_operator_subtask_index_latency_sum(short for latency_sum)
it seems 1) to be the latency value of one real subtask, for 2),latency_count always equal to one const, in my example the value is 128, for 3),latency_sum always equal to zero. could you tell me what's the meaning of 2) and 3)? Best regards & Thanks.
