9.6.4.1 Using Fine-Grained Metrics
Traditionally, Exadata metric collections occur at 1-minute intervals. However, real-time monitoring requires more timely metrics. Commencing with Oracle Exadata System Software 22.1.0, you can configure fine-grained metric collection.
Fine-grained metric collection is the foundation for the Real-Time Insight feature. Fine-grained metric collection works in conjunction with an external metric collection platform, where the fine-grained metric observations are collected and processed for visualization. Fine-grained metric observations reside only in server memory and are not persisted on the server. Consequently, no fine-grained metric history is maintained on each server.
