Device Crawlers greatly simplify the process of surfacing and monitoring environmental monitoring-
oriented OIDs on supported SNMP device through the use of Device Definition Files, or DDFs. DDFs are 
specially prepared data files that isolate and surface the OIDs for specified devices that are of use for 
environmental monitoring purposes. Each DDF file is specifically designed to provide advanced data for 
a particular product set from a particular manufacturer. DDFs are downloaded and installed using the 
Device Definition Files pane in the Device Crawlers task. 

The Device Definition Files pane includes the following information and controls:

To add a new Device Definition File:

1. Click Add/Update Definitions. 

2. The Installation Options window appears. Select the location from which you want to download 

DDFs. Select the Check APC Website radio button to download DDFs from APC, or select the 
Local file radio button to install DDFs from a drive and directory on your system and then click 
Browse and navigate to the directory where the DDF file is stored. Select the DDF and click OK to 
select it.

3. Click Next. A list of available Device Definition Files (including version numbers) appears. Select 

one or more DDFs that you want to install and use with Advanced Device Crawlers and then click 
Next.
