DBbrain's performance trends feature not only supports the selection of multiple performance metrics such as key metrics, all metrics, and custom metrics, but also supports multiple ways to view performance trends, such as fine-grained view of one single performance metric trend, as well as link comparison view and time comparison view of multiple performance metric trends.

Viewing performance trend metrics
1. Log in to the DBbrain console and select Performance Optimization on the left sidebar. On the displayed page, select a database type and an instance at the top, and select the Performance Trends tab.
2. On the Performance Trends tab, select specific performance metrics or select Key Metrics, Select All, or Deselect All in the top-right corner, and click Save.
Note:
Click Save to apply the selected metrics to the current database instance, or click Save and Apply to All Instances to apply the selected metrics to all database instances.
3. View metrics.
Chart interaction: Click Chart Interaction on the right to link and compare the monitoring views of multiple instances or metrics.
When you hover over a data point in any monitoring view, the data at the same time point will be displayed in other monitoring views. Click the data point to pin it for display. To unpin it, click Deselect the Time Point.
Switching between the one-column and two-column modes: Click the button on the right of Chart Interaction in the top-right corner to switch.
Dragging a monitoring view: Click the border of a monitoring view to drag it to the desired position.
Zooming in a monitoring view: Drag the icon in the bottom-right corner of a monitoring view to zoom it in for fine-grained display of the trend of one single performance metric.
Switching between the real-time and historical modes: Click Real-Time or Historical to view the real-time or historical performance trends.
The real-time performance trends view displays the performance trends of the instance and is automatically refreshed by default. You can click Disable refresh to stop refreshing the trends in real time.
In the historical performance trends view, you can select a time range (Last hour, Last 3 hours, Last 24 hours, Last 7 days, or a custom time range) to display the performance trends over the selected time range.
Click Add Time Comparison and select the desired time range for comparison to view the time comparison of multiple performance metric trends.
