If your MongoDB instances run with authentication enabled, ensure Ops Manager has the MongoDB credentials. To learn more, see Configure MongoDB Authentication and Authorization.

If you continue to encounter problems, check the agent's output for errors. To learn more, see Agent Logs for more information.
