Specify Log File Location
On this page
You can specify where MongoDB Shell writes log files. By default,
MongoDB Shell saves the log for each session to your user's
.mongodb/mongosh directory, which depends on your operating system:
Operating System | Default Log Location |
|---|---|
macOS and Linux |
|
Windows |
|
About this Task
To view the current log file location, use the config API to return the logLocation value:
config.get("logLocation")
After you modify your log file location, you must start a new MongoDB Shell session for the change to take effect.
Log File Names
If you modify the default log file location, log files have a
mongosh_ prefix before the session ID. For example, the log for
session ID 67be0c0eb6227e211a1979e8 is saved as
mongosh_67be0c0eb6227e211a1979e8_log.
If you use the default log file location, the file name does not include
the mongosh_ prefix. For example, the log for session ID
67be0c0eb6227e211a1979e8 is saved as
67be0c0eb6227e211a1979e8_log.
Steps
To change the log file location, modify the logLocation
configuration option. You can modify configuration options with the
configuration API or a configuration file.
Important
Specify logLocation as an absolute filepath.
Modify Log Location with the API
The following command uses the config API to set the logLocation
setting to /path/to/log/directory:
config.set("logLocation", "/path/to/log/directory")
Setting "logLocation" has been changed
Modify Log Location with a Configuration File
The following configuration file sets
the logLocation setting to /path/to/log/directory:
mongosh: logLocation: "/path/to/log/directory"
