Mongo forcing a log rotation on Windows

Question

I was wondering how I can setup log rotation for a MongoDB on Windows.

I'm only reading it for Linux and Unix based systems in the documentation. Does anyone know how I can set this up?

Answer 1

I found out that MongoDB has it's own logRoation for Windows build in.

Rotate the log file by issuing the logRotate command from the admin database in a mongo shell:

use admin db.runCommand( { logRotate : 1 } ) 

https://docs.mongodb.com/manual/tutorial/rotate-log-files/#rotate-the-log-file

EDIT:

Stennie told in the comment below that you can even do

db.adminCommand( { logRotate : 1 } ) 

or

db.adminCommand('logRotate') 

Answer 2

That's because log rotation is not a feature of MongoDB but of the Syslog. Windows has completely different object based way of handling this: the Windows Event Log.

If MongoDB on Windows writes log files similar to the Linux/Unix version, you'd need a third party solution for handling the log rotation. There seems to be LogRotateWin.
