SFTP Watcher

Automation Workshop includes SFTP Watcher that works with FTP servers using SFTP protocol on port 22. It also supports SCP file transfers, making it compatible with most Linux, Unix, and BSD systems. For FTPS and FTPES protocol, use the FTP Watcher Trigger.

SFTP Watcher monitors a remote directory on a server for file changes and it can launch a Task when a file or folder is created, modified, or deleted. The Trigger uses polling mechanism that can be tuned to high frequency polling, to achieve almost a real-time file monitoring performance of the remote location · See FTP automation highlights.
