+
+ Generic Kafka Authentication Configuration
+ Failed +
+ Checks if unauthenticated access is enabled. For AWS MSK: Checks if SASL or SSL is configured. For Confluent Cloud/Aiven: Built-in authentication prevents unauthenticated access. For others: Checks if SASL or SSL is configured. Healthy: Authentication is enabled (no unauthenticated access). Failed: Unauthenticated access is enabled (security risk).
+
+
+
+
+
+ š” Recommendation: Enable SASL or SSL authentication in server.properties for better security
+
+
+
+
+

+
+ 
+
+
+ Rack Awareness
+ Warning +
+ Checks if rack awareness is configured in the cluster. Healthy: Rack awareness is configured. Warning: Rack awareness is not configured.
+
+
+
+
+
+ š” Recommendation: Consider enabling rack awareness for better availability and fault tolerance
+
+
+
+
+
+
+
+
+
+
+ Metrics Configuration
+ Warning +
+ Checks if monitoring metrics are properly configured. For AWS MSK: Checks Open Monitoring with Prometheus JMX exporter. For others: Checks JMX metrics configuration. Healthy: Metrics are enabled and accessible. Warning: Metrics are not configured or partially configured.
+
+
+
+
+
+ š” Recommendation: Enable JMX metrics on brokers for better monitoring, alerting, and performance analysis
+
+
+
+
+
+
+
+
+
+
+ Generic Kafka Quotas Configuration
+ Warning +
+ Checks if Kafka quotas are configured and being used. For AWS MSK: Checks quota configuration via AWS console/CLI. For Confluent Cloud/Aiven: Built-in quota management is available. For others: Checks server.properties and kafka-configs.sh for quota settings. Healthy: Quotas are configured and managed. Info: Quotas configuration check available.
+
+
+
+
+
+ š” Recommendation: Configure quotas in server.properties or use kafka-configs.sh to set client quotas for better resource management

+ Checks if payload compression is enabled on user topics. Analyzes compression.type, compression, and producer.compression.type configurations. Healthy: All user topics have compression enabled (100%). Warning: Some or no topics have compression enabled (<100%). Info: No user topics to analyze.
+
+
+
+
+
+ š” Recommendation: Enable compression on topics to reduce storage usage and improve network performance

+
+
+
+
+
+
+
+
+
+
+
+
+
+ Topic Partition Distribution

+
+
+
+
+
+
+
+
+
+ Internal Topics Health
