Interfaces are not displayed in List Resources of a WMI node with SAM installed

Interfaces are not displayed in List Resources of a WMI polled node when SAM is installed.

Note: SAM is a requirement for WMI interface polling. 

There is an issue with the additional polling engine, or the data not being available on the polled node.

Check that the additional polling engine has SAM installed 

1. Establish a remote connection to the additional polling engine.
2. Go to the Control Panel > Programs and Features, or Run > enter appwiz.cpl.
3. Check if SolarWinds Server & Application Monitor vx.x is installed and make sure that it is the same version with the primary server.,
4. If it is not installed, use the Legacy Orion product installers for main poller, additional polling engine, additional web servers, and HA  (v6.3+). For previous releases, the installer is available from the Customer Portal.

Check the source data on the target node 

1. Establish a remote connection to the polling engine that polls the target node.
2. Cick Run, enter 

   wbemtest

   
    and then click Connect.
3. Enter the following parameters:
   • Namespace: \\IPofTarget\root\cimv2
   • User: DOMAIN\Username
   • Password: ********
   • Authority: Leave this Blank
4. Click Connect, and then run the following query:

	SELECT
Name,ConfigManagerErrorCode,InterfaceIndex,MACAddress,Speed,AdapterTypeId,NetConnectionID,NetEnabled 
FROM Win32_NetworkAdapter

       If the interfaces are available and the statistics are missing, run the following query:

SELECT
Name, BytesReceivedPerSec, PacketsReceivedUnicastPerSec, PacketsReceivedNonUnicastPerSec, BytesSentPerSec, PacketsSentUnicastPerSec, PacketsSentNonUnicastPerSec
FROM Win32_PerfRawData_Tcpip_NetworkInterface
