SmbMonitor

This monitor is used to test the NetBIOS over TCP/IP name resolution in Microsoft Windows environments. The monitor tries to retrieve a NetBIOS name for the IP address of the interface. Name services for NetBIOS in Microsoft Windows are provided on port 137/UDP or 137/TCP.

The service uses the IP address of the interface, where the monitor is assigned to. The service is up if for the given IP address a NetBIOS name is registered and can be resolved.

For troubleshooting see the usage of the Microsoft Windows command line tool nbtstat or on Linux nmblookup.

Microsoft deprecated the usage of NetBIOS. Since Windows Server 2000 DNS is used as the default name resolution.
