1-2: Helpful overview!The introduction provides a clear and concise overview of the new metrics collection and export feature in the Java client. It sets the context for the changes introduced in this file.
9-40: LGTM!The
PrometheusApolloClientMetricsExporterclass structure and method signatures are well-defined. The class extends the appropriate base class and implements the required interface. The method names are descriptive and follow the naming conventions.
60-68: Initialization looks good!The
doInit()method correctly initializes theCollectorRegistryand the map to store metrics. The introduction of the Prometheus Java client dependency is justified and necessary for integrating with Prometheus.
84-120: Implementation looks solid!The
registerOrUpdateCounterSample(...)andregisterOrUpdateGaugeSample(...)methods are implemented correctly. The logic for registering and updating counters and gauges follows the best practices of checking for the existence of a metric before creating a new one. The code is readable and well-structured.
125-136: Response method looks good!The
response()method is implemented correctly and follows the expected format for Prometheus. The use ofStringWriteris appropriate for writing the metrics, and the error handling is adequate, logging an error message if the write operation fails.docs/en/extension/java-client-how-to-use-custom-monitor-system.md (1)
1-141: Excellent documentation for creating a custom metrics exporter!The documentation provides clear step-by-step instructions on how to create a custom metrics exporter for the Apollo Java client to integrate with Prometheus. The code examples are well-structured and cover key aspects such as initialization, metrics registration, and response generation.
This will greatly help users extend the Apollo Java client for monitoring purposes. Great work!

704-729: Comprehensive metrics data table!The metrics data table provides a good overview of the key metrics exported by the Apollo client. The metrics cover important aspects like configuration usage, thread pool performance, and exceptions. The naming convention for metrics and tags is consistent and descriptive.
1498-1507: Flexible MetricsExporter extension mechanism!The MetricsExporter extension provides a powerful way for users to integrate Apollo client metrics with their preferred monitoring systems. The SPI and abstract class offer flexibility and simplify the implementation of custom exporters. This extension aligns well with the enhanced observability features in version 2.4.0.
422-422: Skipping static analysis hints.The flagged punctuation marks are used appropriately in the configuration keys. Specifying a language for the code block and adding alternate text for images would be nice enhancements but are not critical in this context.

docs/zh/extension/java-client-how-to-use-custom-monitor-system.md (4)
44-69: LGTM: Clear explanation and proper initialization indoInit().The explanation of the
doInit()method is clear, and the implementation correctly initializes the PrometheusCollectorRegistryand a map for storing metrics.Consider adding a brief comment above the
doInit()method to explain its purpose, like this:/** * Initializes Prometheus-specific objects for metric collection. */ @Override public void doInit() { registry = new CollectorRegistry(); map = new HashMap<>(); }
71-80: LGTM: Clear explanation and correct implementation ofisSupport().The explanation of the
isSupport()method is clear, and the implementation correctly checks if the exporter supports the "prometheus" form.For improved clarity and maintainability, consider defining a constant for the "prometheus" string:
private static final String PROMETHEUS_FORM = "prometheus"; @Override public boolean isSupport(String form) { return PROMETHEUS_FORM.equals(form); }This makes it easier to update the supported form in the future if needed.
82-121: LGTM: Correct implementation of Counter and Gauge metric handling.The
registerOrUpdateCounterSample()andregisterOrUpdateGaugeSample()methods are implemented correctly, handling both new and existing metrics appropriately. The code follows Prometheus Java client conventions.For consistency, consider using the same pattern for both Counter and Gauge creation methods:
private Counter createCounter(String name, Map<String, String> tags) { return Counter.build() .name(name) .help("Apollo metric: " + name) // Add more descriptive help text .labelNames(tags.keySet().toArray(new String[0])) .register(registry); } private Gauge createGauge(String name, Map<String, String> tags) { return Gauge.build() .name(name) .help("Apollo metric: " + name) // Add more descriptive help text .labelNames(tags.keySet().toArray(new String[0])) .register(registry); }This change adds more descriptive help text for each metric, which can be useful for users of the monitoring system.
123-141: LGTM: Correct implementation ofresponse()method and helpful conclusion.The
response()method is implemented correctly, properly handling the export of metrics in Prometheus format and managing potential IOExceptions. The conclusion and link to the full code are helpful for users who want to see the complete implementation.To address the Markdownlint warning and improve the link's appearance, consider formatting the URL as a proper Markdown link:
完整代码：[PrometheusApolloClientMetricsExporter.java](https://github.com/apolloconfig/apollo-java/main/master/apollo-plugin/apollo-plugin-client-prometheus/src/main/java/com/ctrip/framework/apollo/monitor/internal/exporter/impl/PrometheusApolloClientMetricsExporter.java)This change will make the link more readable and comply with Markdown best practices.

9-42: Consider adding comments for empty method bodies.The class structure is well-defined. However, to improve readability and avoid confusion, consider adding comments in the empty method bodies to indicate that implementations will be provided later in the document.
For example:
@Override public void doInit() { // Implementation provided later in the document }
58-69: Consider explaining the purpose of the cache map.The Prometheus-specific initialization is well-explained, and the code snippet is clear. However, it would be helpful to briefly explain the purpose of the cache map (map). This would provide readers with a better understanding of its role in the metrics collection process.
For example, you could add:
// map is used to cache metric collectors for efficient lookup and updates private Map<String, Collector.Describable> map;
71-80: Add a note about the PROMETHEUS constant.The explanation of the isSupport method is clear, and the code snippet effectively demonstrates its implementation. However, the PROMETHEUS constant used in the isSupport method is not defined in the visible context.
Consider adding a note to explain where this constant is defined, or include its definition in the code snippet. For example:
private static final String PROMETHEUS = "prometheus"; @Override public boolean isSupport(String form) { return PROMETHEUS.equals(form); }This will provide readers with a complete understanding of the method's implementation.
123-141: LGTM: Clear implementation of the response method. Fix the link format.The explanation and implementation of the response method are clear and effective. The method correctly exports data in the Prometheus format and handles potential IOExceptions.

401-418: Improve configuration documentation formatting.Consider enhancing the readability of the configuration section by:
- Using a table format to present the configuration properties
- Adding example values for each property
- Including default values in the description
Example table format:

553-582: Enhance metrics documentation with descriptions.The metrics tables would be more helpful with detailed descriptions for each metric, including:
- What the metric measures
- Units of measurement
- Common troubleshooting scenarios
- Recommended thresholds if applicable
For example:
## Namespace Metrics | Metric Name | Labels | Description | Unit | |-------------|--------|-------------|------| | apollo_client_namespace_usage_total | namespace | Total number of times a namespace has been accessed | count | | apollo_client_namespace_item_num | namespace | Number of configuration items in a namespace | count |docs/en/client/java-sdk-user-guide.md (1)

1284-1285: Enhance the load balancer documentation section.While the documentation introduces the ConfigService load balancer feature, it could be improved by:
- Adding code examples showing how to implement a custom load balancer
- Including configuration steps to enable a custom implementation
- Explaining the SPI registration process
- Documenting the method(s) that need to be implemented
- Adding best practices and considerations when implementing a custom load balancer
Consider adding the following template for implementing a custom load balancer:
public class CustomConfigServiceLoadBalancer implements ConfigServiceLoadBalancerClient { @Override public ServiceDTO select(List<ServiceDTO> configServices) { // Custom load balancing logic here return configServices.get(0); // Example implementation } }

public class RoundRobinConfigServiceLoadBalancerClient implements ConfigServiceLoadBalancerClient { private AtomicInteger index = new AtomicInteger(0); @Override public ServiceDTO select(List<ServiceDTO> services) { if (services == null || services.isEmpty()) { return null; } return services.get(Math.abs(index.getAndIncrement() % services.size())); } }

401-418: Enhance the monitoring configuration documentation.Consider the following improvements:
- Add a table to better organize the configuration properties and their default values
- Include examples for each configuration property
- Add cross-references to related sections

1437-1575: Enhance the custom implementation example.The example could be improved with:
- Better error handling in the
response()method- Documentation for each method
- Configuration examples
- Testing guidelines
Add method documentation like this:
/** * Prometheus metrics exporter implementation for Apollo client monitoring. */ public class PrometheusApolloClientMetricsExporter extends AbstractApolloClientMetricsExporter { private static final String PROMETHEUS = "prometheus"; private static final Logger logger = LoggerFactory.getLogger(PrometheusApolloClientMetricsExporter.class); /** * Initialize the Prometheus registry and metrics cache. */ @Override public void doInit() { registry = new CollectorRegistry(); map = new HashMap<>(); } // Add similar documentation for other methods... }🧰 Tools

401-440: Improve properties format for better readability and usability.The configuration documentation is well structured, but the properties format can be improved by using a more copy-paste friendly format with comments.
Consider using this format for the properties:
# Enable Monitor mechanism, ConfigMonitor will be enabled, default is false apollo.client.monitor.enabled=true # Expose Monitor data via JMX, can be viewed through tools like J-console, default is false apollo.client.monitor.jmx.enabled=true # Maximum number of exceptions stored by Monitor, follows FIFO principle, default is 25 apollo.client.monitor.exception-queue-size=30 # Specify the Exporter type for exporting metrics data to monitoring systems # Available values depend on the MetricsExporter SPI implementations apollo.client.monitor.external.type=prometheus # Specify how often the Exporter exports state information as metrics data, default is 10 seconds apollo.client.monitor.external.export-period=20
1467-1615: Fix code indentation to use spaces instead of tabs.The custom monitoring integration documentation is comprehensive, but the code formatting should be consistent.
Replace tabs with spaces in the code examples to maintain consistent formatting throughout the documentation.
