MongoDB connector showing a Dashboard Alert message "Increase Oplog Retention Period"
Connector - MongoDB
To resolve this Alert message and prevent potential issues with losing the Oplog state, contact your DBA to set your Mongo Oplog Retention Period to between 24 hours and 7 days, as per our Mongo DB Setup Guide.
This Alert message is displayed if your Oplog Retention Period is between 8 and 24 hours.
The reason for this is there is a higher likelihood of losing the Oplog state, which would then result in an automatic re-sync of the connector.
