Win32-PerfRawData-Tcpip-NBTConnection - WMI Perl sample
The foundations for Manageability in Windows 2019/2016/2012/2008 and Windows 10/7/XP are Windows Management Instrumentation (WMI; formerly WBEM) and WMI extensions for Windows Driver Model (WDM).
ActiveXperts Network Monitor provides the ability to build monitor check routines based on WMI. ActiveXperts has collected more than a hundred WMI samples. You can use these samples as a base for new check routines you can write yourself.
On this site, you can find many WMI samples.
The Win32_PerfRawData_Tcpip_NBTConnection WMI class can be used in ActiveXperts Network Monitor to monitor your servers.
Win32-PerfRawData-Tcpip-NBTConnection
Description
The Win32_PerfRawData_Tcpip_NBTConnection raw data performance counter class represents raw data counters that measure the rates at which bytes are sent and received over the NBT connection between the local computer and a remote computer. The connection is identified by the name of the remote computer. This class is shown as the NBT Connection object in System Monitor. The WMI source of its data is the high-performance Performance Counter Provider. The original data source is the Tcpip performance library. The corresponding formatted data class is Win32_PerfFormattedData_Tcpip_NBTConnection. This class was added for Windows 2000.
