Starting from Spring Boot 3.2 (using micrometer-registry 1.12 [1]) counters now have exemplars per default (with no possibility outside code changes to disable). This change causes problems, when using Managed Prometheus, as counters with exemplars are not supported (preventing ingestion of metrics)[2]. Prometheus starting from version 2.43.0 provides support [1]. As of now, we have reverted micrometer-registry to 1.11.8 - however - this is not a correct solution.

We expect Manged Prometheus to ensure compatibility in storing data with Prometheus. Given the volume of users, esp. enterprise, using Spring Boot we expect this to become a significant cause of concern for users if not corrected. For our client, if this issue can't be corrected, we will revert from Managed Prometheus.

Hello! Sorry to bring up this issue after almost a year but I wanted to add that we have chosen metric identifier as

agent.googleapis.com/memory/percent_used but autoscaling didnt work out for us either. It would be appraciated if you can guide us.

Hi, at the moment we are using the cpu_utilization/target_utilization attribute (in app.yaml) for autoscaling in the app engine flexible environment, however it would be great if we can have the way to mention the memory_utilization metrics as well to decide on the auto scaling. It will give us more control of the auto scaling the instances than now.
