Configure OIDs for Attributes

Configure OIDs for Attributes


Role Required: SDAdmin
 
When an SNMP device is identified using its sysOID, the inventory will be initiated to fetch values of the device attributes. These attribute values are obtained through OID queries as each attribute is linked to a unique OID in the application database. However, there are instances where the OIDs for attributes are not accessible or are linked to the wrong attributes. In such cases, modify the OID configurations to avoid fetching incorrect data.

Steps to Configure OIDs for Attributes   

Go to Admin > Discovery > SNMP Configurations > Device Inventory and follow the steps below.


 

Step 1: Choose the Product Type 

Choose the product type whose attributes need OID configuration. You can also choose a specific manufacturer for the selected product type.
 
Once the product type is selected, all attributes of the selected product type will be listed.
 
From the list of attributes, select the field that needs OID configuration. Alternatively, you can click Configure OID and choose the attribute.


 

Step 2: Fetch OID from MIB   

The OID must be fetched from the corresponding device's MIB file, obtained from the manufacturer and uploaded into the application.
  1. Click From MIB on the displayed pop-up window.

  1. Under the From MIB section, choose the corresponding device's MIB file. You can also directly upload the MIB file here.
  2. Under the MIB tree, choose the MIB node corresponding to the attribute. You can expand and view all MIB nodes, or use the Search button.
 
Once you select the MIB node, the corresponding OID will be displayed on the respective field.
 

Step 3: Test the OID chosen 

You can sample query a device and check whether the OID fetched from the MIB file returns the right value for the attribute.

To sample query a device, 
  1. Click Test Device displayed under the From MIB section.

  2. Enter the device's hostname or IP address, choose the device's credentials, and click Get.


  1. The attribute value returned will be displayed.
  2. Use the Clear button to wipe out the listed attributes.
 

Step 4: Specify the Unit 

Only applicable for size attributes
When you configure an OID for size attributes, you must identify and specify the unit in which the value will be returned. Values returned for size attribute values will be converted and displayed across the application in just two units—Bytes, KB, and MB will be converted to GB, and GB will be converted to TB.

 

Step 5: Save the OID 

After completing the OID configuration, testing, and unit specification, click Save Attribute. You can edit the OID and associated details at any time.
