Abstract: These DECnet network monitoring programs are essentially the same displays shown at DECWORLD '87 in Boston, MA. There are several data collection programs as well as display programs which monitor a DECnet network, as well as terminal servers and LAN bridges. The set of tools is called NETSTAT.

The DECnet event processor program and the DECnet area and node polling program gathers reachability information and stores it in shared data structures. The area and node display programs periodically read these data structures and update the graphical display boxes by shading them either red for an alarm condition or green for reachable.

The terminal server polling program uses TSM V1.2 (Terminal Server Manager software) to interrogate all known terminal servers on the Ethernet LAN. This information is stored in a shared data structure. The terminal server status display program operates in the identical manner as does the node display program described above.

The bridge server polling command procedure uses RBMS V1.1 (Remote Bridge Management software) to interrogate all known LAN bridges on the extended Ethernet LAN. This information is stored in a shared data structure. The bridge status display program operates in the identical manner as does the node display program described above.

Each display program is independent of the other so only those displays that are of interest to the user need be run. The graphical display programs use VAX BASIC V3.0 (or higher) and the associated graphics commands. This requires VAX GKS V2.0 or higher.
