Non-Prometheus Micrometer implementations only expose few C8 metrics #26078
Description
Describe the bug
I would like to use a different backend than Prometheus for metrics with my C8 deployment. Unfortunately, when I configure one (e.g. Dynatrace), I only see a handful of C8 metrics. I would like to have access to the same metrics as the Prometheus backend.
To Reproduce
- Enable the metrics endpoint via
management.endpoint.metrics.enabled=true - Enable the simple metrics backend via
management.simple.metrics.export.enabled=true - Query
http://localhost:9600/actuator/metrics
You will only see the few metrics from Zeebe which are registered via Micrometer, instead of via Prometheus.
Expected behavior
All metrics are emitted by C8 are visible in every Micrometer backend (except for those who do not support certain types).
Environment:
- Zeebe Version: >= 8.6.+
