AI-Powered Kafka Health Assistant

Kadeck 5.0 introduces a groundbreaking AI-powered Kafka Health Assistant. Whether you are new to Kafka or an experienced pro, the AI Assistant will help keep your Kafka infrastructure operating smoothly 24 x 7. It continuously assesses the health of your Kafka clusters, topics, consumers, and partitions and automatically recommends changes that will improve performance and avoid downtime.

Kafka monitoring section

Kadeck 5.0 also introduces a Kafka monitoring module. The Kafka monitoring module contains three new dashboards: Monitoring Overview, Broker monitoring and Topic monitoring that visualize real-time and historic Kafka key performance metrics such as:

  • I/O
  • Throughput
  • Storage
  • Replicas
  • Consumer group status
  • Partition and leader skew
  • And many more

The Kafka Monitoring module is the perfect complement to Kadeck. It makes Kadeck the industry’s most complete Kafka performance solution, allowing you to not only monitor, but also analyze and troubleshoot Kafka performance quickly and confidently from a single platform.

Consumer Monitoring Enhancements

Kadeck contains many features for analyzing and reconfiguring Kafka consumers and consumer groups. Kadeck 5.0 introduces a new ability to view consumers and consumer lag grouped by topic. In this view, the total lag of all consumer groups is aggregated for each topic, which makes it easy to see whether certain topics are experiencing lag problems.

The new Health Assistant monitors your consumer groups and notifies you, if, for example, a consumer group is not consuming from all partitions of a topic which can lead to data loss.

Kafka Connect auto-restart

To make it easier for infrastructure and operations teams to ensure higher uptime, the new Health Assistant can monitor and restart crashed Kafka Connect tasks. This helps ensure data streaming continuity 24x7 with less manual oversight.

Other Kadeck Enhancements

  • Navigate records in the data browser using the arrow keys
  • Topic details view no longer closes if you click a record twice
  • Protobuf Codec improvements
  • Table shows total items now
  • Security improvements
