        // Fall back to direct server query
        return directory.performDirectEnumeration();
    }
}
```

## 10. Monitoring and Metrics

### 10.1 Directory Cache Statistics
```java
public class DirectoryCacheStatistics {
    private final AtomicLong cacheHits = new AtomicLong();

    
    // Should work even if RDMA provider is not available
    file.createNewFile();
    assertTrue(file.exists());
}
```

## 8. Performance Monitoring

### 8.1 RDMA Statistics
```java
public class RdmaStatistics {
    private final AtomicLong rdmaReads = new AtomicLong();
    private final AtomicLong rdmaWrites = new AtomicLong();

 * <h4>Frameworks</h4>

 * <p>When chaining together a graph of asynchronous operations, you will often find it easier to
 * use a framework. Frameworks automate the process, often adding features like monitoring,
 * debugging, and cancellation. Examples of frameworks include:

```java
public class HandleStatistics {
    private final AtomicLong handlesRequested = new AtomicLong();

You can use simple tools like `htop` to see the CPU and RAM used in your server or the amount used by each process. Or you can use more complex monitoring tools, which may be distributed across servers, etc.

## Recap { #recap }

You have been reading here some of the main concepts that you would probably need to keep in mind when deciding how to deploy your application:
