MongoDB Shell uses ndjson to store session logs. Starting in mongosh version 1.0.5, the log MongoDB Shell format is updated to match the MongoDB server log format. For details, see Log Messages.

You can view or tail the logs for a MongoDB Shell session based on its log ID.


The MongoDB Shell redacts credentials from the command history and the logs.
