THE DDFR ARCHIVER CHAPTER 5: RETRIEVING AND VIEWING DDFR ARCHIVER DATA
Note
While the Archiver can be based in a local (on-site) computer, it is usually based in a
remote (off-site) location in order to fully centralize the gathering of data from DDFR
units in all the separate physical locations (see figure 5.1).
FIGURE 5–1: Remote Archiver Location
Refer to Chapter 3 for the procedure for configuring the DDFRs. All DDFRs must be
configured with a valid IP address in order for the DDFR Archiver to monitor them.
Note
The DDFR Archiver accesses DDFRs using HTTP Protocol through port 80. If the host
computer has either an XP’s Windows Firewall or a 3rd party Firewall installed, make the
appropriate changes to the firewall’s exception settings to allow the Archiver to
communicate with the DDFRs.
5.1.1.2 Archiver Features
Because the Archiver is closely associated with the DDFR units themselves, many of the
Archiver’s features are the same as, or similar to, the features of these DDFR units.
• Continual monitoring of the status of communications between the host computer
and the DDFRs for which it is configured to archive data.
