Next scheduled scan and run scan on demand

From the All Connections index page, when you select a connection you are routed to a screen that provides detailed information for that connection. In the top right corner, you can see the time and date of the next scheduled scan. From there, you can choose to run a scan on demand or activate and deactivate the scan via the status pill.

Last Scan Report

You can pull the Last Scan Report at any time to get a real time view of the current status of your infrastructure.

The report, displayed on the right pane, includes the Scanned Device per Type. To better understand the details provided, we have included the table below.

Status Description
Scanned Devices

Total scanned devices per Connection:

  • SCCM - Number of hosts in the database
  • Router - Based on the ARP table size
  • vCenter - Number of hosts in the database
  • Subnet - Subnet size
  • SolarWinds Platform nodes Discovery
  • AWS Cloud Discovery
  • Azure Cloud Discovery
  • Jamf Cloud Discovery
Devices Updated Any change in device information, when compared to the previous scan, leads to a database update.
New Devices Detected Any device that has responded to a ping request for the first time.
Responded Devices

Total number of devices recognized as active:

  • Subnet - Number of devices Nmap has identified as active
  • Router - Based on the ARP table size
  • SCCM - Number of hosts in the database
  • vCenter - Number of hosts in the database
Discarded Devices

An IP address alone is not a sufficient factor to uniquely identify an asset. Therefore, the discovery process will discard any asset that does not possess a unique identifier, such as a MAC address or serial number.

In cases where a MAC address is not detected by the scanner, there are multiple options to provide clarity:

  • Provide additional credentials such as WMI, SNMP, or other credential.
  • Locate the scanner on the same physical subnet.
  • Provide SNMP credential to the router to allow the import of the ARP Table.
Skipped Devices

Devices that have not been reported for one of the following reasons:

  • There is an agent installed on the host. The device is already recorded.
  • The device has already been detected, scanned, and reported on by another mechanism (for example, SCCM).

Intune

In addition to the table above, you are able to pull fields from your mobile devices via Intune, which is a part of Microsoft Endpoint Manager. Below is a list of data pulled:

  • Owner
  • Manufacturer
  • OS Version
  • Serial Number
  • IMEI Number
  • IP Address
  • Wi-Fi Mac
  • ICCID
  • App List

See Intune configuration for instructions on integrating Intune with SWSD.

Data collection via WMI

Windows Management Instrumentation (WMI) provides the ability to obtain management data from remote computers in an enterprise environment operating on Windows OS.  This is accomplished via remote WMI connections made through Distributed Component Object Model (DCOM).

If you want to use WMI, use User and Password on a subnet connection.

Address security measures

The security measures below must be addressed to ensure proper access to data.

  1. Ensure firewall allows WMI access.

  2. Disable UAC filter by following these steps:

    1. Navigate to Start.

    2. Type: firewall

    3. Select Allow a program through Windows Firewall.

    4. Select Change settings.

    5. Select Windows Management Instrumentation (WMI), and then click OK.

  3. If it is necessary to allow for a specific user:

    1. Run wmimgmt.msc.

    2. Right-click WMI Control (local).

    3. Select Properties > Security tab > click Security > Add.

    4. Type the name of the user into Enter the object names to select.

    5. Click Check names, and then click OK.

    6. Click Advanced.

    7. Double-click the specific user.

    8. For Applied to select This namespace and subnamespaces.

    9. Select both:

      • Remote Enable
      • Execute Methods

    10. Runnet localgroup "Distributed COM Users" USERNAME /add

    11. Replace USERNAME (For example IE11WIN10\IEUser)
