logRotate

The logRotate command is an administrative command that allows you to rotate the MongoDB logs to prevent a single logfile from consuming too much disk space. You must issue the logRotate command against the admin database in the form:

{ logRotate: 1 }

Note

Your mongod instance needs to be running with the --logpath [file] option.

You may also rotate the logs by sending a SIGUSR1 signal to the mongod process. If your mongod has a process ID of 2200, here’s how to send the signal on Linux:

kill -SIGUSR1 2200

logRotate renames the existing log file by appending the current timestamp to the filename. The appended timestamp has the following form:

<YYYY>-<mm>-<DD>T<HH>-<MM>-<SS>

Then logRotate creates a new log file with the same name as originally specified by the systemLog.path setting to mongod or mongos.

Note

New in version 2.0.3: The logRotate command is available to mongod instances running on Windows systems with MongoDB release 2.0.3 and higher.
