How log file rotation works

You must be aware of how log files are rotated in System Manager in order to save space, to easily maintain data, and to secure data.

You can use the log files generated by System Manager to debug issues because these files record the operations performed by System Manager. Because the number of log files increase with the operations performed, they are rotated to save system space and to ease file management.

The System Manager log files are rotated when its size crosses 10 MB. After the first rotation of the log files, the log files are renamed System Manager.log.1 and subsequent logs are written to SystemManager.log. When the size of SystemManager.log exceeds 10 MB, the log files are renamed SystemManager.log.1 and the older SystemManager.log.1 files are renamed SystemManager.log.2. Similarly, the log files are rotated five times and at any time there is a maximum of six log files, namely, SystemManager.log, SystemManager.log.1, SystemManager.log.2, SystemManager.log.3, SystemManager.log.4 and SystemManager.log.5. When all these log files are available in the system and when the size of SystemManager.log exceeds 10 MB, the rotation is repeated as described, and the existing SystemManager.log.5 is removed, and SystemManager.log.4 is renamed SystemManager.log.5.

The log files are stored as SystemManager.log in the following locations:

•	C:\users\<user>\NetApp\SystemManager if System Manager is running on Windows Vista, Windows 7, or Windows Server 2008 operating system.

•	C:\Documents and Settings\<user>\NetApp\SystemManager if System Manager is running on versions older than Windows Vista operating system.

•	<user_home>/NetApp/SystemManager if System Manager is running on Linux operating system.
