Re: what's the meaning of latency indicator reported by flink metrics through prometheus?

1) correct
2) is the number of measurements; due to the random distribution of latency markers this value can be surprisingly low depending on the latency marker interval
3) I don't know, but it isn't exposed by Flink.

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:
for latency)
for latency_count)
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
for 3),latency_sum always equal to zero.

could you tell me what's the meaning of 2) and 3)?

Best regards & Thanks.
