What is it?​

The File Activity Detection (FAD) Daemon is a component of the Unix Agent that monitors directories for file changes and forwards OpCon events to the SAM. It uses a control file to define which directories to watch and what events to send when file activity is detected. System Administrators configure and maintain the FAD Daemon to support event-driven job automation on Unix machines.
