Viewing and Managing Discovery Results

The Discovery tab (Network Explorer > Discovery) provides detailed information about NetMRI discovery processes through a special Discovery drop-down menu. To open the menu, click the down arrow on the Discovery tab.

Use this tab and menu to perform the following:

  • View discovery and data collection processes in real-time. IP addresses are listed as they are discovered from any source.
  • View discovery milestones and status, which provide a context for fixing problems.
  • Monitor IP address processing to gauge overall progress.
  • Correlate device IP addresses with management IP addresses.
  • Search all known IP addresses.
  • View and control credential guessing queues. You can see where a device falls in the sequence, and prioritize it if desired.
  • Tell NetMRI to immediately perform the full discovery process on a device. Results are displayed when received.
  • Administer devices to view and change licensed/unlicensed/unmanaged status.
  • "Unmanage" a discovered device, set the licensing status for a device, delete a device from the list, and do other operations.

The following views are available via the Discovery menu:

Recent Activity

Lists all known IP addresses discovered by NetMRI.

License Management

Provides data similar to Recent Activity, sorting the list according to priority in the algorithm for determining where a device fits in the device license scheme. This view helps determine why a given device is or is not licensed, where it is on the list to change the NetMRI license (if necessary) or to adjust a setting so a given device is given license priority.

Problems

Provides data similar to Recent Activity, but filtered to devices reporting discovery errors.

Non-Detected IPs

Provides data similar to Recent Activity, but filtered to devices that NetMRI has not been able to communicate with.

SSH Queue, Telnet Queue, and SNMP Queue

Shows whether a given device is in the processing queue for determining credentials. Data about each device in the queue includes the time of the prior attempt, time the device is going to be attempted again, and status. SNMP discovery is the key to complete device discovery. Until a device has fully discovered SNMP credentials, data collection and analysis cannot continue.

Note

Operations Center only: Data displayed in a view is limited to the Collector selected in the Filter by Collector field on the right side of the header.

The area at the bottom of the Discovery tab provides the following summary data for the selected collector:

  • Network Devices: The number of devices discovered.
  • Licensed Devices: The number of licensed devices discovered.
  • IP Addresses:
    • Classified: The number of IP addresses the appliance has fully discovered with SNMP collection and assigned to a device group.
    • Reached: The number of IP addresses NetMRI has touched.
    • Identified: The number of IP addresses known to exist on the network.

For more information about interpreting discovery data that the previous views display, see the next section Interpreting Discovery Table Data.

Sometimes a device may be discovered by more than one collector. In that case, a deduplication procedure occurs and the device is marked with a special icon in the UI. For more information, see Deduplication of Devices Discovered by Multiple Collectors.
