Description

Historically the SDP has been provisioning the JMX exporter to expose metrics in products, but Java products increasingly expose Prometheus metrics natively.

HBase and Spark are such examples.
We want to switch from the JMX exporter to the native integration while ensuring a smooth migration path for all users.

Value

Removing the JMX exporter will get rid of metric inconsistencies, reduce complexity and increase security by removing a dependency.

Tasks

We will split this into multiple epics because it'll span multiple SDP releases:

• Part 1 for SDP 25.7: Enable native Prometheus endpoints where available #735
• Part 2 for later

Acceptance Criteria

• All reference to the JMX Exporter have been removed for products that natively support Prometheus
• All demos and tests have been migrated to potential new metrics endpoints and labels => ttps://github.com/Update monitoring stack to SDP 25.7 and scrape all products demos#284
• Especially the monitoring stack "just works" for all products. Update monitoring stack to SDP 25.7 and scrape all products demos#284 initially already did this. This task is about checking that nothing broke!
• Users had at least one release to migrate from the old to the new metrics
