Remote File Monitor Task

Remote File Monitor Task

Overview

The Remote File Monitor task allows you to monitor for a file on a remote machine where an FTP server is running. The Remote File Monitor connects to the FTP server rather than the machine's file system to monitor for files. The Remote File Monitor can be used only within a workflow; you cannot run a Remote File Monitor task based on a trigger. To run a Remote File Monitor task, you need Universal Agent to communicate with the FTP server. The Agent can, but does not have to be, running on the same machine as the FTP server.

In the following example, the user wants to monitor for a file on a remote FTP Server that has an Agent running on it. In this case, the login credentials for the Agent machine and the FTP server machine are the same.
 


 

In the following example, the user wants to monitor for a file on a remote FTP Server that does not have an Agent running on it. In this case, the Remote File Monitor task definition provides an address and login credentials for the machine where the Agent is running as well as address and login credentials for the FTP server.
 

Built-In Variables

The following built-in variables can be used in a Remote File Monitor task to pass data where appropriate:

Creating a Remote File Monitor Task

Step 3

Click a Save button. The task is added to the database, and all buttons and tabs in the Task Details are enabled.

Note

To open an existing record on the list, either:

  • Click a record in the list to display its record Details below the list. (To clear record Details below the list, click the New button that displays above and below the Details.)

  • Clicking the Details icon next to a record name in the list, or right-click a record in the list and then click Open in the Action menu that displays, to display a pop-up version of the record Details.

Monitor Type

Wait until Satisfied

Poll Interval (Seconds)

If Wait until Satisfied is enabled: Frequency, in seconds, in which the Remote File Monitor will check to see if the file exists or is missing.

Maximum Polls

If Wait until Satisfied is enabled: Maximum number of times that the Remote File Monitor will check to see if the file exists or is missing.

Stable (Seconds)

If Wait until Satisfied is enabled: Period of time, in seconds, during which the file has not changed.
 
For a Remote File Monitor task, a file's stability depends on its size. If the file size displayed in the FTP/SFTP output does not change during the specified number of seconds, the file is considered stable. In order for the task to reliably monitor the file's stability, the task must display a file's size in a well-known location. This means that the file list returned in the output must be in Unix long-listing format, as follows:
 

 
The task will only find the size if it is in the 5th column (for example, 12345 in the example above).
 
The default file list format varies across different FTP client/server implementations, but most support additional commands that can force the output to the required format. The Additional FTP Commands field is provided to insert those statements into the FTP script that the file monitor task executes.

The Remote File Monitor Task Exclude Protocols Universal Controller system property permits the exclusion of one or more, but not all, protocols (server types) from being selected.)
