this.settings = Objects.requireNonNull(settings, "settings must not be null");
}
```

**Logging with Context:**
```java
if (logger.isInfoEnabled()) {
    logger.info("Creating suggest index: index={}, searchAlias={}, updateAlias={}",
                indexName, getSearchAlias(index), getUpdateAlias(index));
}
```

**Exception Handling:**
```java
try {

import javax.security.auth.callback.UnsupportedCallbackException;
import javax.security.auth.login.Configuration;
import javax.security.auth.login.LoginContext;
import javax.security.auth.login.LoginException;

import org.slf4j.Logger;

### 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

import org.opensearch.transport.client.ClusterAdminClient;

/**
 * Test class for FesenClient to verify improvements made to the implementation.
 */
public class FesenClientTest {

    private static final Logger logger = LogManager.getLogger(FesenClientTest.class);

    private FesenClient fesenClient;
    private Client mockClient;

    @Before
    public void setUp() {
        fesenClient = new FesenClient();

	}

		return
	}

	// Tags XML will not be bigger than 1MiB in size, fail if its bigger.
	tags, err := tags.ParseObjectXML(io.LimitReader(r.Body, 1<<20))
	if err != nil {
		writeErrorResponse(ctx, w, toAPIError(ctx, err), r.URL)
