You can log on to the ApsaraDB for MongoDB console or call the DescribeParameterModificationHistory operation to view the parameter modification history.

Prerequisites

The target instance must be a standalone or replica set instance. Sharded cluster instances do not support this feature.

Procedure

  1. Log on to the ApsaraDB for MongoDB console.
  2. In the upper-left corner of the home page, select the region where the target instance is located.
  3. In the left-side navigation pane, click Replica Set Instances.
  4. Locate the target instance and click its instance ID.
  5. In the left-side navigation pane, choose Parameters > Modification History.

    On the Modification History page that appears, modification records of the last 24 hours are displayed by default. You can also specify a time range to query parameter modification records.
