Your application could maybe also expose http_apdex_target_seconds with the correct label.

Okay, would not %g render +inf, Nan etc out of the box as we would expect?

> The advantage with using a numeric , instead of a hard coded label, is that I can use max/min to pick if two different versions of the same app...

I will ping @juliusv and @beorn7 for their opinion on this.

It feels like this is easily done (openmetrics -> text format): ``` metric_relabel_configs: - source_labels: [le] target_label: le regex: '([0-9]+)\.0' ``` The other way around (text format -> openmetrics): ```...

Thanks, I have updated my comment.

Saying that OM uses %g is incorrect. We are using %g in the text format too: https://github.com/prometheus/common/blob/main/expfmt/text_create.go#L449 Somehow %g does not add the .0 and we artificially add it in...

> On a side note, purely out of curiosity, would that le relabeling impact exemplar lookup? It should yes.

cc @GiedriusS Can you please address Julius' comment and rebase this pull request please? Thanks!

Yes, I am waiting for more details and a proper PR from alibaba.
