GKE/Micometer/Managed Prometheus - Custom metrics do not show up

[OlafTh]

Hi,

We have developed our own custom metrics, but even six hours after we upgraded the application, the metrics do not show up in the list for "Manage Metrics". We can see them when we curl the endpoint.

Will they show up by themselves? When? Or do we need to do something, and if so: what?

Thanks,

Olaf

Hi @OlafTh!

Welcome to the Google Cloud Community!

Several factors can prevent custom metrics from appearing as expected, making it challenging to pinpoint the exact issue without reviewing your specific setup. A common cause of such problems often lies in the scrape configuration. If the Prometheus sidecar or agent isn't correctly configured to discover and scrape metrics from your application, it won't collect any data. Additionally, issues with the metric exporters themselves can lead to collection problems.

I hope this helps. Please don't hesitate to contact Google Cloud Support if you're still having the issue. Thank you.
