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

MongoDB Shell saves a history of all commands you've run across sessions. When a new command is issued, it is added to the beginning of the history file.
Open the following file in a text editor to view the MongoDB Shell command history:
Operating System | Path to History File |
|---|---|
macOS and Linux | ~/.mongodb/mongosh/mongosh_repl_history |
Windows | %UserProfile%/.mongodb/mongosh/mongosh_repl_history |
Log Retention
mongosh retains log files for 30 days. Log files older than
30 days are automatically deleted.
