SFTP watcher · Overview

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 of Linux, Unix, and BSD systems. For FTPS and FTPES protocol, use 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 from the remote location.

Optionally, the SFTP watcher Trigger can scan directories for files to reach certain limits in file size, or number of files. File mask filter allows to monitor for selected file types or files with specific names, such as Word documents or .pdf files. On most Linux compatible systems, it allows filtering files by their owner and group, as well as, by filesystem permissions.
