Database Autonomy Service (DAS) provides the Performance Trend feature. This feature offers a wide range of performance monitoring metrics, supports custom charts, and includes powerful diagnostics capabilities that allow you to run diagnostics for a specific time range. This helps you better understand the operational status of your database instance.
Prerequisites
The target database instance is connected to DAS, and its connection status is Normal. For more information, see Connect an instance.
Features
The Performance Trend feature includes metrics such as Transaction Per Second (TPS), queries per second (QPS), and throughput.
The monitoring granularity, or frequency, of metrics depends on the query time range. A wider time range results in a coarser granularity.
Procedure
