How to view real-time performance-ApsaraDB for MongoDB(MongoDB)-阿里云帮助中心

ApsaraDB for MongoDB provides real-time performance metrics, including read/write latency, QPS, operations, connections, and network traffic, so you can monitor instance health as it happens.

Prerequisites

The instance must be a replica set instance or a sharded cluster instance that uses the MongoDB protocol.

Procedure

Go to the Replica Set Instances or Sharded Cluster Instances page. In the top navigation bar, select the resource group and region, and then click the target instance ID.
In the navigation pane on the left, click CloudDBA > Real-time Performance.
Monitor real-time performance trends and view mongostat command output.
Note
Refreshing or revisiting the Real-time Monitoring page restarts data collection for the real-time charts and mongostat output and resets the Available Refreshes counter in the upper-right corner.
- Real-time Charts
  
  Real-time line charts refresh every 5 seconds, letting you track performance trends at a glance.
  
  Note
  Click the icon above a chart to view details about the metric.
- Mongostat
  
  A new row of real-time performance values appears every 5 seconds, up to 999 rows. ApsaraDB for MongoDB uses mongostat v0.1. For more information about the output fields, see the official MongoDB documentation.
