### Debug Logging

Enable debug logging by adding to your logging configuration:

```xml
<logger name="org.codelibs.fess.crawler" level="DEBUG"/>
<logger name="org.codelibs.fess.crawler.client" level="DEBUG"/>
<logger name="org.codelibs.fess.crawler.extractor" level="DEBUG"/>
```

### Monitoring

```java
// Monitor crawling progress

			debug.PrintStack()
		}
		return b
	}

	m.mu.RUnlock()
	m.mu.Lock()
	defer m.mu.Unlock()
	// See if someone else fetched it while we waited for the lock.
	b, ok = m.buckets[bucket]
	if ok {
		if b.bucket != bucket {
			logger.Info("getBucket: newly cached bucket %s does not match this bucket %s", b.bucket, bucket)
			debug.PrintStack()
		}
		return b
	}
