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

4. A list of the DDFs you have selected appears. Click next to download and install the selected DDFs.

After you have installed a Device Definition File any previously added targets that are defined by the 
contents of the DDF will now have the Advanced Data sensor set available.

When an SNMP target that includes Advanced Data is selected from the Navigation pane or from a Pod 
selection list in the Alerts or Graphs view, the Advanced Data sensor set will be displayed by default. The 
Advanced Data sensor set consists of all supplemental OIDs that have been surfaced from the SNMP 
target using an installed DDF. 

Once Advanced Data is available for use on an SNMP target, you can easily monitor and receive alert 
notifications for any target OIDs that are surfaced by Advanced Device Crawlers, just like any other 
monitored value on a pod or SNMP target. For information on how to define thresholds and specify 
sensor settings on Advanced Data sensor values, see “Sensor Settings” on page 81.

Even if advanced data is not available for some of your SNMP targets, you can still configure Advanced 
Device Crawlers to monitor individual OIDs on your target. While not as simple as using the surfaced 
OID data provided by a Device Definition File in an Advanced Data sensor set, you can use the Add 
Supplemental OID function to manually configure Advanced Device Crawlers to monitor any valid OID 
on your SNMP targets.

The Supplemental OID view displays a list of any currently defined supplemental OIDs, as well as a user-
defined description of the OID. To add a supplemental OID:

1. Click Add.

2. The Add Supplemental OID window opens.

3. Type in the OID field the OID that you want to monitor on the selected SNMP target (for example, 

“1.3.6.1.4.1.318.1.1.1.2.2.2”).

4. Type in the Description field a description of the OID (for example, “UPS Temperature”). 

5. Click OK. Advanced Device Crawlers will then query the SNMP target to determine whether the 

OID you entered is valid and if so to determine what sort of data is returned by the OID, whether the 
data can be treated as an analog sensor or a state sensor, and so forth. If the OID is valid it will be 
added to the Advanced Data sensor set. 

Once the supplemental OID has been added, it will automatically be detected on any SNMP target to 
which it applies, and you can easily monitor and receive alert notifications for it just like any other 
monitored value on a pod or SNMP target. For information on how to define thresholds and specify 
sensor settings on Advanced Data sensor values, see “Sensor Settings” on page 81.

The Advanced Data sensor set is available only for SNMP target devices which 
are defined by a separately installed Device Definition File.
