Database Autonomy Service (DAS) lets you monitor database performance through interactive trend charts. DAS automatically detects events, runs diagnostics, and surfaces root cause analysis — so you can identify and resolve issues faster. You can also select any time range and trigger diagnostics manually.
Prerequisites
Before you begin, make sure that:
The database instance is connected to DAS and is in the Accessed state
Dashboard overview
The Dashboard page groups performance monitoring into five tabs, each covering a distinct analysis workflow:
| Tab | What it does |
|---|---|
| Performance Trends | View trend charts for metrics like transactions per second (TPS), queries per second (QPS), and throughput across a selected time range |
| Performance Trend Comparison | Compare how a metric behaves across different time ranges side by side |
| Custom Chart | Build monitoring dashboards with the specific metrics you want to track |
| Exception Detection | View anomaly detection results and predictions for core metrics |
| Instance Topology | View the topology of the instance |
Monitoring granularity: The sampling frequency shown in each chart adjusts automatically based on the time range you select. A longer time range results in coarser granularity.
View performance trends
Log on to the DAS console.
In the left-side navigation pane, choose Intelligent O&M Center > Instance Monitoring.
Find the instance and click its instance ID.
In the left-side navigation pane, click Dashboard.
On the Dashboard page, use the tabs to monitor performance as described below.
Performance Trends tab
On the Performance Trends tab, view trend charts for metrics within a selected time range.
Add metrics: Click More Metrics and select the metrics to display.
View metric details: Click the
icon next to a metric name.Diagnose a time range: Drag to select a time range in a trend chart, then click Diagnose to analyze performance within that range.
Expand a chart: Click Details in the upper-right corner of a trend chart. Change the time range to update the view.
Monitor events: Select one or more event levels. DAS displays detected events in the trend charts of main metrics. Click an event to view its diagnostic result.
Performance Trend Comparison tab
On the Performance Trend Comparison tab, compare the trend of a metric across different time ranges.
Click More Metrics to select the metrics for comparison.
Custom Chart tab
On the Custom Chart tab, create monitoring dashboards with the metrics you want to track. Adding multiple metrics to a single dashboard makes it easier to correlate data during troubleshooting and performance analysis.
Click Add Monitoring Dashboard. In the Create Monitoring Dashboard dialog box, enter a dashboard name and click OK.
Click Add Node and Metrics. In the Select Metrics of Monitoring Chart dialog box, select the nodes and metrics to include, then click the
icon.Click OK.
Exception Detection tab
On the Exception Detection tab, view anomaly detection results and predictions for core metrics. For more information, see Performance anomaly detection.
Click More Metrics to select which metrics to include in exception detection.
Instance Topology tab
On the Instance Topology tab, view the topology of the instance.
