Question
The MongoDB connector shows the dashboard alert message, Increase Oplog Retention Period.
Environment
Connector: MongoDB
Answer
To resolve this alert message and prevent potential issues with losing the Oplog state, please contact your DBA to set your Mongo Oplog retention period to between 24 hours and 7 days, as per our Mongo DB Setup Guide.
Cause
This Alert message is displayed if your Oplog retention period is between 8 and 24 hours. This is because there is a higher likelihood of losing the Oplog state, which would then result in an automatic re-sync of the connector.
