> Exposing Go runtime metrics is extremely useful to enhance supportability and it makes it easier to reason about the performance of YK (memory usage, GC usage, etc).
> Possible approaches:
> * Use direct Go API calls to {{ReadMemStats()}} [1] and {{ReadGCStats()}} [2]
> * Use the more generics metrics under {{runtime/metrics}} [3]
> * Combination of these
> [1] https://pkg.go.dev/runtime#ReadMemStats
> [2] https://pkg.go.dev/runtime/debug#ReadGCStats
> [3] https://pkg.go.dev/runtime/metrics
