@wineman3 As described in the doc, the library provides either a histogram or the summary. So what you see are not just single metrics - but parts of the histogram, see https://prometheus.io/docs/concepts/metric_types/#histogram
I don't see, how the parts you're not interested in are so bad that you'd add any code or complexity to remove them. You may reduce the buckets by providing just one bucket. But that's max effort I would put into it.
Also I wonder, how is the sum
alone of any use for you at all? Actually the division of sum
by count
gives you the average latency. I thought that's the whole point of the histogram. Average latency and corresponding count of hits all delivered with just 2 values. Isn't that cool?

Yeah sorry, my mistake. We use sum and count but the bucket/histogram metrics not as much. I can definitely see the value in them, it's more so an effort to reduce cardinality on our organization's Prometheus server.

well, as I said my solution would be to provide buckets: []
. This will result in exactly one bucket (+Inf), which will be the same as count. So you get 3 values instead of 2 you need.
But hey, for an edge case of a guy, who isn't interested in the fact that some of requests are REALLLY slow but are missed because of the averages (this is the point of buckets), it should be good enough.
I'm really reluctant of going away form histogram, cause it's indeed a good practice.

@wineman3 please forgive my tone in the previous comment. It was an unjustified arrogance on my side.
Closing the issue, hopefully you came to an adequate solution.

@disjunction no worries! I really appreciate your help. Itβs honestly given me insight to utilize the histogram metrics some more, and I may go that route now, this was just direction from leadership on my team but I may push back to utilize the histogram approach more extensively. Thanks again!
