> When moving from micrometer to otel for metrics, we lost metrics for system
> memory. It is a useful metric and we should re-introduce total and free
> values.
> Since java do not (yet) have a full public api for this, we can use
> com.sun.management.OperatingSystemMXBean which is supported on the most used
> JVMs. On unsupported JVMs the metric should not be reported.
>
> Naming suggestion: jvm_system_memory_total_bytes and
> jvm_system_memory_free_bytes
