We could expose the metrics by adding these methods to the
`KeyValueStorageRocksDB` class.
```java
public long cacheMisses() throws IOException {
return statistics.getTickerCount(TickerType.BLOCK_CACHE_MISS);
}
public long cacheHits() throws IOException {
return statistics.getTickerCount(TickerType.BLOCK_CACHE_HIT);
}
```
We might have trouble integrating them with the current `StatsLogger`
because there is no way to register counters. If you look at the
`EntryLocationIndexStats`, you'll see that it relies on registering a gauge.
These metrics are not gauges though, so it could lead to some minor confusion
when interpreting the metrics output.
