Discovering assets

Devices that are connected to the network but on which no BMC Client Management (BCM) agent is installed can be remotely inventoried by any CM agent, which collects the software and hardware inventory of these devices.

Unmanaged devices in BCM are devices of your infrastructure that:

  • Are never connected to the network or
  • Do not have a BCM agent installed

Nevertheless, BCM provides possibilities to inventory (hardware and software) these devices and include the generated inventories in the BCM database. The custom inventory for unmanaged devices can only be created directly in the BCM console.

The Asset Discovery functionality of BCM allows you to scan your network or parts of your network for all existing assets. It finds all types of assets, PCs, printers, routers, and so on, with and without CM agent installed. The discovery also scans the devices for their basic information such as operating system and inventories and displays these in the console window.

Components

Asset Discovery in BCM is done via a number of different components and objects listed in the following, and on which you can see detailed information in the following sections and topics:

  • Asset discovery scanner
    The Asset Discovery Scanner is any device in your network, defined as the scanner. It is responsible for the whole scanning process. By default the master is predefined as the scanner, but any other device with a reasonably strong configuration fitting the previously mentioned requirements can take over this role.
  • Discovered device inventory
    The discovered device inventory for a device or a group is an extraction of the inventories available and generated by the BCM agent, that is, it generates the discovered hardware, software and parts of the security inventory for all discovered assets as well as the connectivity inventory, that is, the actual physical connections between the devices.
  • Asset discovery wizards
    BCM also has a wizard that guides you through the different options of scanning your network devices and launching the scans.

Prerequisites

The following prerequisites must be fulfilled for asset discovery to be operable:

  • To see a list of supported operating systems of the scanner device, see Software requirements.
  • The master/scanner should have a permanent Internet connection, preferably via Ethernet, it mustnot use a wireless connection.
  • IPv6 addresses are supported by the asset discovery, however, be aware that specifying complete IPv6 subnets can take a very long time. It is recommended not to do so.
  • Set LocalAccountTokenFilterPolicy to 1 in registry so that you can access Windows 10 inventory via remote WMI and local credentials.

    Windows 10 inventory via remote WMI and local credentials will give access denied. BCM Asset Scan discovery showing RED DOT for WMI on machines where you defined local credentials for scan.

    example failure (remote query using local account with admin) : C:\mstsc>wmic /user:".\localSA" /node:w10d bios get serialnumber Enter the password :***********

    Node - w10d ERROR: Description = Access is denied.

    See for article below to support this tip on registry key to add. reg add "hklm\software\microsoft\windows\currentversion\policies\system" /v LocalAccountTokenFilterPolicy /t reg_dword /d 1

    local credentials used for discovery will fail on WMI for Windows 10 unless LocalAccountTokenFilterPolicy set to 1 in registry.
