Figure 5-23 illustrates four additional features not covered in the preceding figures:
display of last events for a subject, loading of filters, display of event detail, and printing
of screen messages as a printed log. These features are separately discussed in the next
four paragraphs.
The last-events distributor examines all event messages that come in to the NCN event
log. All event messages that pass the existing last-events filter (which selects subjects
of interest) are sent to the last-events collection server (a ViewPoint event collection
server) for recording in the last-events database. The event messages in this database
are organized on the basis of subjects. Thus, the events-display process (when you
request the Last Events screen) can retrieve the most recent page of event messages for a
given subject.
You load an alternate-events filter (as shown earlier in Figure 5-17) by entering a filter
file name on the Event Configuration screen and pressing the Configure function key.
This causes the ViewPoint TCP to send a command directly to the specified alternate-
events distributor process. The distributor reads the filter from the specified file and
loads the filter into the data space of the distributor's filter in memory. (Filters for
primary events and last events are loaded only when ViewPoint is started.)
