Some JVM signals updates due to otel semantic convention update:

  1. Otel semconv v.1.22 version introduced breaking change in jvm runtime metrics. (just like windows-exporter)
  2. so
  3. New metrics are defined in observ-lib as described here in the latest spec https://opentelemetry.io/docs/specs/semconv/runtime/jvm-metrics/ in "otel_with_suffixes"
  4. previous otel metrics are moved to "otel_old" and "otel_old_with_suffixes"

P.S. _with_suffixes means with_suffixes is enabled as remote remotewrite option, which is default OTEL to prometheus translation suffixes in alloy and otel-collector.
More on this: https://opentelemetry.io/docs/specs/otel/compatibility/prometheus_and_openmetrics/#otlp-metric-points-to-prometheus
