```
current: {metadata: {units: {name: "bytes", type: "numeric"}}}

proposed: {metadata: {unit: "bytes", type: "numeric"}}
```

proposed feels more accurate

also, it seems like there may be value in specifying type based on the types added by Gary with the statsd changes, rather than saying numeric for everything. Understanding that something is a counter/timer/histogram/etc seems like it has value.
