Working with OS file systems using Fleet Manager

You can use Fleet Manager, a tool in Amazon Systems Manager, to work with the file system on your managed nodes. Using Fleet Manager, you can view information about the directory and file data stored on the volumes attached to your managed nodes. For example, you can view the name, size, extension, owner, and permissions for your directories and files. Up to 10,000 lines of file data can be previewed as text from the Fleet Manager console. You can also use this feature to tail files. When using tail to view file data, the last 10 lines of the file are displayed initially. As new lines of data are written to the file, the view is updated in real time. As a result, you can review log data from the console, which can improve the efficiency of your troubleshooting and systems administration. Additionally, you can create directories and copy, cut, paste, rename, or delete files and directories.

We recommend creating regular backups, or taking snapshots of the Amazon Elastic Block Store (Amazon EBS) volumes attached to your managed nodes. When copying, or cutting and pasting files, existing files and directories in the destination path with the same name as the new files or directories are replaced. Serious problems can occur if you replace or modify system files and directories. Amazon doesn't guarantee that these problems can be solved. Modify system files at your own risk. You're responsible for all file and directory changes, and ensuring you have backups. Deleting or replacing files and directories can't be undone.
