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.

After the first rotation of the log files, the log files are renamed System Manager_x.log.1, where x is the System Manager version, and subsequent logs are written to SystemManager_x.log. When the size of SystemManager_x.log exceeds 10 MB, the log files are renamed SystemManager_x.log.1 and the older SystemManager_x.log.1 files are renamed SystemManager_x.log.2. Similarly, the log files are rotated five times and whenever there is a maximum of six log files, namely, SystemManager_x.log, SystemManager_x.log.1, SystemManager_x.log.2, SystemManager_x.log.3, SystemManager_x.log.4 and SystemManager_x.log.5. When all these log files are available in the system and when the size of SystemManager_x.log exceeds 10 MB, the rotation is repeated as described, the existing SystemManager_x.log.5 is removed, and SystemManager_x.log.4 is renamed SystemManager_x.log.5.

The log files are stored as SystemManager_x.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.
