});
```

### 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

	req := logger.GetReqInfo(ctx)
	if req != nil {
		req.Lock()
		defer req.Unlock()
		req.Objects = make([]logger.ObjectVersion, 0, len(objects))
		for _, ov := range objects {
			req.Objects = append(req.Objects, logger.ObjectVersion{
				ObjectName: ov.ObjectName,
				VersionID:  ov.VersionID,
			})
		}
		return logger.SetReqInfo(ctx, req)
	}
	return ctx
}
