Kudu

Apache Kudu is a real-time storage engine in the Hadoop ecosystem, designed for fast analytics on columnar data. It combines HDFS’s high throughput with HBase’s low latency to support both high-speed ingest and low-latency queries—ideal for time-series analytics, operational dashboards, and interactive applications.

Kudu Monitoring with Pulse

Pulse provides deep visibility into Kudu’s performance and health through intuitive dashboards and detailed metrics:

• Cluster Health: Track master/tablet server status, Raft leadership, and storage directories
• System Usage: Monitor CPU and memory for master and tablet servers
• Storage Insights: View block cache activity and storage utilization
• Row Operations: Analyzes inserts, updates, deletes, and compactions
• Latency and Throughput: Monitor RPC rates, latency, and slow scans

Key Benefits

Some of the benefits of using Pulse include:

• Faster Issue Detection: Spot endpoint failures, resource bottlenecks, and latency spikes early
• Optimized Resource Use: Monitor system metrics to ensure efficient use of hardware
• Improved Reliability: Get alerts for service interruptions or slowdowns to prevent downtime
• Better Troubleshooting: Use detailed insights from metrics and logs for faster root-cause analysis
• Actionable Dashboards: Build custom views with DashPlot to focus on what matters most

Kudu Logs and Node Health

In the Pulse UI, navigate to the Logs and Nodes pages to monitor Kudu operations and infrastructure:

• Logs Page: View detailed Kudu logs (info, warning, error) to troubleshoot failures and track service behavior. For more details, see Logs.
• Nodes Page: View real-time metrics like CPU, memory, and disk usage, and application status for each node running Kudu. For more details, see Nodes.

These pages provide operational insights to ensure performance, identify degradation, and maintain uptime.

Kudu Alerts

Pulse continuously monitors the health of the Kudu service and raises alerts when endpoints become unavailable. Also, you can create custom alerts for the metrics you want to monitor closely with specific conditions. For more information, see Monitor Kudu with Pulse Alerts.

Kudu Metrics in Pulse UI

In the Pulse UI, select Kudu from the left navigation panel. Key metrics and charts appear instantly. This gives you a complete picture of service behavior.

Explore the subpage for detailed insights into compaction activity, block cache usage, rowset patterns, and other performance metrics.

Pulse shows Kudu metrics in the form of summary panels and charts covering Master and Tablet Server health, Block Cache and RPC performance, and RowSet activity and transaction summary.

This helps you understand service status and operational activity. For more information, see Kudu Dashboard.
