You can select multiple performance metrics for Redis performance trends. Specifically, you can switch instances (Redis database instances), Redis nodes (between nodes, such as between node A and node B), and proxy nodes (middleware cluster nodes). You can also select performance metrics, such as real-time/historical views, monitoring granularities, single metric view/comparison view, and multiple views and comparison views of instances, Redis nodes, and proxy nodes.

Viewing performance trends
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. Set monitoring metrics.
Metric categories: Include CPU, memory, network, latency, request, and response.
Select performance metrics: You can select all metrics, custom metrics, and various views.
Filter global metrics
Filter one single metric
Switch between chart views
3. Set the monitoring dimension.
You can set the monitoring dimension to Instance, Redis Node, or Proxy Node.
Instance: It displays the monitoring view of the entire instance.
Redis Node: It displays the comparison trend views of relevant metrics on each Redis node.
Proxy Node: It displays the comparison trend views of relevant metrics on each proxy node.If you select Proxy Node, you can select the Aggregate view or Node view.
In Aggregate view mode, the information of all proxy nodes is displayed. You need to select a metric in the top-left corner to display the single-metric information of all nodes. Click Details next to each metric to enter the Node view.
In Node view mode, the information of all monitoring metrics of a node is displayed.
4. Switch between the Real-Time and Historical views.
DBbrain allows you to switch between real-time and historical data. According to the selected time view, different granularities are provided. Single metric view and comparison view are also available.
5. Enable chart interaction.For one single instance, node, or proxy, you can view relevant metric trend comparison, add custom metrics, and view the performance metric trend comparison by time.
After you enable chart interaction, 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.
6. Show statistics.
Metric monitoring charts support displaying specific monitoring data simultaneously. After Show Statistics is enabled, the table data will be displayed below each monitoring chart.
7. Switch between the one-column and two-column modes, drag a monitoring view, or zoom in a monitoring view.
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.
