Performance trends
CloudDBA performance trends monitors key metrics and running trends of an ApsaraDB for MongoDB instance over a specified time period, including CPU utilization, memory usage, total connections, and network traffic.
Prerequisites
The instance must be a standalone instance, a replica set instance, or a sharded cluster instance that uses the MongoDB protocol.
Procedure
Log on to the ApsaraDB for MongoDB console.
In the left-side navigation pane, click Replica Set Instances or Sharded Cluster Instance based on the instance type.
In the upper-left corner of the page, select the resource group and region to which the instance belongs.
On the page that appears, find the instance that you want to manage and click its ID.
- In the left-side navigation pane, choose Performance.
Node list
The Performance Trend page displays a Nodes section that shows basic information and key metric trends for each node in the instance.
Performance trends
Three viewing modes are available: Performance Trend, Performance Trend Comparison, and Custom Charts.
- Performance Trend: Displays trend charts for each metric over a specified time period. Each chart represents a single metric.

- Performance Trend Comparison: Compares metric trends across two time periods to help identify performance differences and locate root causes. Each chart represents a single metric. Select a target node, specify two time ranges, and click View. Use the Chart Layout drop-down list to adjust the number of charts displayed per row. Enable the chart linking switch to synchronize timelines across all charts. The page displays trend comparison line charts for metrics such as MongoDB CPU Utilization (%) and Opcounters.
- Custom Charts: Analyzes trends for selected metrics. For detailed instructions, see Custom performance trend charts.Note By default, Correlation Chart is enabled. When you hover over a point on one chart, all other charts synchronize to the same point in time.
