SNA Server can also support integrated management services with IBM NetView network management systems that run on IBM mainframes, as shown in Figure 10.36.
The NetView reporting system sends alerts and other information between a host system and the computers that connect to it. NetView functionality can be extended to encompass the Windows 2000/SNA Server environment through the following services:
Figure 10.36 SNA Server Communication with IBM NetView
As shown in Figure 10.36, the NVAlert service sends events from the Windows 2000 event logs to IBM NetView system on the host computer. The events are sent as standard NetView alerts. NVAlert can send two categories of events: events generated by the Windows 2000 operating system and events generated by Windows 2000–based applications.
The events can be forwarded to the NetView console display on the host system or to a host system log file. NVAlert determines which events to forward to the NetView console by reading the NVAlert.ini file.
The NVRunCmd service allows commands issued from a host system NetView console to be carried out on the computer running Windows 2000 and SNA Server. The NVRunCmd service also returns the command results to the host NetView console in standard character or number formats.
The Response Time Monitor (RTM) is an IBM host function that works in conjunction with NetView and 3270 sessions to measure the length of time it takes for a host to respond during a 3270 session. The SNA Server Response Time Monitoring tool allows you to specify when RTM should send data and to define the triggers that cause RTM to register that the host has responded.
When a Synchronous Data Link Control (SDLC) or Token Ring connection fails, SNA Server logs diagnostic information, called link alerts, about the connection failure. The alerts are logged in a log file that can be viewed using the Windows 2000 Event Viewer.
The link alerts are also used to build a network management vector transport (NMVT) alert, which includes probable causes and suggested actions for the alert. If a connection on the server running SNA Server has been designated for NetView, and the connection is active, the NMVT alert is sent on that connection.
For more information about SNA Server management services, including integration with Windows 2000 and IBM host management services, see the SNA Server version 4.0 documentation.
