Hello!
Can you help me?
I have a summary metric
http_server_requests_seconds{instance="", quantile="", uri=""}
http_server_requests_seconds_count{instance="", uri=""}
http_server_requests_seconds_sum{instance="", uri=""}
and I'm trying to figure out how to calculate the 95 quantile across all
instances.
I know that there is no way to aggregate the quantile of Summary, but I
want to try to implement the formula:
(quantile95_instance_1 * count_instance_1 + ... + quantile95_instance_N *
count_instance_N ) / (count_instance_1 + ... + count_instance_N)
However, when I multiply http_server_requests_seconds *
http_server_requests_seconds_count, there is no data in the response
Do I understand correctly that:
1. In the Summary type, mathematical operations can only be applied to the
_sum and _count metrics?
2. This is because the _sum and _count metrics are consistent in time with
each other, while the metric with quantile is not?
3. And if point 1 is correct, is it possible mathematically or in some
other way for this metric to calculate the 95 quantile across all instances.
