Discovery and Inventory Group

Troubleshooting Tips

From the data Mapping section in the previous article (9).

• Have you selected the device mapping for the device being inventoried? You can review this in the Discovered Devices report in Network Discovery. The Manufacturer, Model should match what is placed in the mappings.
• Do you have more than one device mappings that might apply to this device? Make sure all are checked.
• Does the machine respond to the OIDs you have selected to be queried via SNMP? See the section for troubleshooting that covers the SNMPutilg.exe utility for how to test this.
• Check the Notification Server logs at the time the Discovery completed as the engine will drop the NSEs with the data into the queue for processing. Look for errors relating to the processing of that data. If no errors or warnings are seen, the data was likely processed correctly.

Agentless Inventory Task

Now that all the preliminary work has been completed, the task can now be run. Most of the work is done on the back end, so running the task is fairly painless. Follow these steps to run the task:

1. In the Symantec Management Console, browse under Manage > Jobs and Tasks > and in the left-hand tree browse under System Jobs and Tasks > Discovery and Inventory > Right-click on Discovery and Inventory and choose New > Task.
2. In the task tree, look under the section for Discovery and Inventory and select Inventory for Network Devices.
   
3. Provide a name, such as “Agentless Inventory for Cisco Switches”.
4. Select the group of devices to Inventory. Note that the default organizational groups will not allow a lot of specific targeted. For example I selected Infrastructure Device, which will include all Cisco Switches, but will also include any other Infrastructure device found in that group. If you want to be more specific, create your own Organizational Group to select.
5. Alternatively you can select an individual device. This is recommended when testing the Task to limit how much activity the Task causes.
6. You also have the option to check the box for inventory devices not inventoried in a defined number of days. Use this as necessary to limit the traffic on the network if needed, otherwise it is recommended to keep this unchecked so to ensure data integrity.
7. Ignore the Advanced button.
8. Click OK to save the Task.
9. Once back to the main console, click on the New Schedule button.
10. Set a scheduled time or choose now to run the Agentless Inventory.
11. When complete, the new inventory should be appended to the targeted devices, including the new custom data classes configured previously (if applicable via device mappings).

Troubleshooting Tips

• When you’ve selected a group, does the device you expect to inventory reside in that group? Check by browsing under Manage > All Resources and browsing to and selecting the group. Look for the device in the right-hand list. Alternatively you can test the task against the device specifically using the “Individual device” radial option.
• Did the task complete successfully? Double-click on the Task Status row for the instance you ran. This will provide statistics and statuses for the task, and you can review if the task has completed and what the outcome was.
• Double-check data mappings if a device is not inventoried as expected (for example it collects the standard default tables but not the custom one).
