SMA File Activity Daemon Features and Descriptions​

Recognition of file names​

  • The SMA FAD recognizes individual file names and masks containing wildcards.
  • The SMA FAD allows overlapping file names or wildcard specifications to support processing of different events.
  • Refer to the <filemask> Control File element.

Recognition of file creation​

  • The SMA FAD checks for file creation.
  • The SMA FAD treats file existence the same as file creation.
  • Refer to the <condition> Control File element.

Recognition of file deletion​

  • The SMA FAD checks for file deletion.
  • The SMA FAD treats file absence the same as file deletion.
  • Refer to the <condition> Control File element.

Recognition of change in file size​

  • The SMA FAD checks for any changes in the file size (i.e., increase or decrease) and initiates the associated events.
  • Refer to the <condition> Control File element.

Recognition of file modification​

  • The SMA FAD recognizes when a file has been modified.
  • Refer to the <condition> Control File element.
Note

The SMA FAD processes events for file modification separately from events for change in file size.

Support the initiation of events in specified time slots only​

  • If specified in the control file, the SMA FAD triggers the external events only if the conditions are met within a specific period of time.
  • Refer to the <window> Control File element.

Ability to specify a time interval between initiation of events​

  • If configured to trigger multiple events upon certain file criteria, the SMA FAD can wait a user-defined number of seconds between events.
  • Refer to the <sleep> Control File element.

Read the control file at a configurable interval​

  • By default, the SMA FAD reads the control file every one second; however, the administrator can configure other intervals.
  • Refer to the <waittimebetweenpasses> Control File element.
