Can't get the metrics info by metrics_prometheus crate

[Ma1oneZhang]

I used to register the foyer crate metrics into my own prometheus registry like belowing code

metrics_prometheus::install();
// do something

But after the version update(0.10.1 => 0.11.1), i can't use it to access th metrics in foyer crate anymore.

How can i solve the problem?

Hi @Ma1oneZhang . Thank you for reporting.

Would you mind provide more information about the environment? Like metrics-prometheus version you are using, are you using non-default metrics registry, etc.

If you are using non-default registry, you can refer to the docs of metrics-prometheus, or sample usage in RisingWave.

I'm using default registry, i just repair some update changes and the metrics not working anymore.

BTW, the version of metrics-prometheus is 0.7.0, the foyer is the lastest version 0.11.1 with mtrace feature.

And the version of metrics and metrics-prometheus?

FYI: instrumentisto/metrics-prometheus-rs#10

Verified with @Ma1oneZhang offline. This is caused by they are using wrong registry. Close.
