This topic describes how to view the real-time performance of MongoDB databases.
Database Autonomy Service (DAS) allows you to view the global real-time performance of all the MongoDB instances. DAS also allows you to view the real-time performance of each MongoDB database instance. This helps you check the database performance in real time during stress testing or promotion activities.
You remain logged on to the DAS console.
The target database instance is connected to DAS, and the target database instance is in the Accessed state. For more information about the procedures, see Connect ApsaraDB for RDS database instances and Connect user-created database instances.
In the left-side navigation pane, click Instance Monitoring. On the page that appears, find the target database instance.
In the Actions column for the target instance, move the pointer over Performance. Then, select Real-time Monitoring from the Performance drop-down list.
On the Real-time Monitoring page, you can view the performance metrics of the MongoDB instance in real time. The performance metrics include the read/write latency, queries per second (QPS), operations, connections, cache usage, network throughput, and queued reads/writes.
Two types of views are available: real-time charts and real-time mongostat tables.
On the Real-time Monitoring Dashboard page, you can view the real-time performance of all the MongoDB instances.
