Use the parameter modification history to audit configuration changes and investigate performance issues. The Modification History tab shows what changed, the values before and after the change, modification status, and modification time.
Prerequisites
Before you begin, ensure that you have:
An ApsaraDB for MongoDB replica set instance or sharded cluster instance
Access to the ApsaraDB for MongoDB console
View modification history
Go to the Replica Set Instances or Sharded Cluster Instances page. In the top navigation bar, select the region where the instance resides, then find the instance and click its ID.
In the left-side navigation pane, click Parameters.
Click the Modification History tab.
The page shows modification records for the last 24 hours by default. To query a different time range, specify a custom start and end time.
