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, your current MongoDB Shell session continues to use the previous log file location. Sessions that start after you change the log file location use the updated location.
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"
