CloudDBA provides the performance trends feature to monitor the basic performance metrics and corresponding performance trends of an ApsaraDB for MongoDB instance over a specified time range. These performance metrics include CPU utilization, memory usage, total number of connections, and network traffic. This topic describes how to view the performance trends of an ApsaraDB for MongoDB instance.

Prerequisites

The instance is a standalone, replica set, or sharded cluster instance.

Procedure

  1. Log on to the ApsaraDB for MongoDB console.
  2. In the upper-left corner of the page, select the resource group and the region of the target instance.
  3. In the left-side navigation pane, click Replica Set Instances, or Sharded Cluster Instances based on the instance type.
  4. Find the target instance and click its ID.
  5. In the left-side navigation pane, choose CloudDBA > Performance.

Nodes

On the page that appears, you can view the node ID, role, specifications, maximum number of connections, CPU utilization, and memory usage in the Nodes section.

Note If the instance is a standalone instance, the Nodes section is not displayed.

Performance trends

This section provides the Performance Trends, Performance Trend Comparison, and Custom Chart tabs.

  • Performance Trends: displays the trend charts of metrics over a specified time range. Each chart visualizes a metric. Performance Trends tab
  • Performance Trend Comparison: displays the trend charts of metrics over two specified time ranges. For example, the following figure shows the trend charts over the same time range on January 07, 2021 and January 08, 2021. The trend comparison charts help you identify drops in performance and further investigate the cause. Each chart visualizes a metric. Performance Trend Comparison
  • Custom Chart: You can present multiple metrics for a specified time range in a single trend chart. Each chart visualizes multiple metrics. For more information, see Customize a performance trend chart. Custom Chart tab
Note
  • By default, Correlation is enabled. When you move the pointer over a chart to view the performance data of the instance at 09:00:00, all charts display the corresponding performance data.
  • In the upper-right corner of the chart that you want to view, you can click Definition? to view the definitions of metrics and click Details to view a larger performance trend chart.
