Monitor Kudu with Pulse Alerts
Pulse alerts help you monitor the health and availability of Kudu services by continuously checking key metrics and triggering notifications when issues are detected.
You can:
- Enable built-in stock alerts to automatically track when Kudu Master or Tablet Server services become unreachable.
- Enable predefined alerts that run multiple queries to detect more complex issues.
- Create custom alerts to monitor specific Kudu metrics, such as slow scans, failed RPCs, memory usage, etc., with defined threshold conditions.
These alerts allow you to detect failures early, respond faster to service degradation, and maintain system reliability.

You can enable built-in stock and predefined alerts, customize and enable stock and predefined ones, or create your own to track specific metrics with conditions.
