Customizing ViewPoint
Introduction
The ViewPoint application is an extensible Pathway application that you can use as a 
foundation for your software. This section describes the ways you can extend or 
customize the ViewPoint software for your system and network management needs. It 
describes how to:
•
Add custom event-message filters and process operator-supplied filter parameters.
•
Add advisory text to be displayed for individual event messages on the Event Detail 
screen.
•
Alter the prefix text that is displayed for individual events on the Primary, 
Alternate, and Last Events screens.
•
Determine whether or not the events in the cache will be retrieved when ViewPoint 
is restarted following a CPU failure or an intentional shutdown.
•
Add TACL macros and routines to be started from the TACL screen (if the 
ViewPoint application provides access to TACL).
•
Add Extras screens to provide additional functions including the capability to 
control deletion of events.
•
Manage the addition of items to the status display.
•
Obtain information about installing and using ViewPoint with the DSM/Problem 
Manager (DSM/PM) product.
•
Obtain information about installing and using ViewPoint as part of the Integrated 
Operations Console (IOC) product set. IOC consists of the following products: 
NetCommand, NetStatus, DSM/PM, and ViewPoint.
Before using the information in this section, you should be thoroughly familiar with the 
features and architecture of the ViewPoint application as described in previous sections 
of this manual. You should also refer to Section 7, Installation, Configuration, and 
Startup for information on configuring your customized application.
If you are writing custom event-message filters, you should be familiar with the event-
management filter language and compiler, as described in the EMS Manual. If you are 
adding Extras screens, you should be familiar with Pathway SCREEN COBOL 
programming. If you are adding items to the status displays, you should be familiar 
with writing Pathway servers. 
Note. This section describes most of the ViewPoint software interfaces that use the DDL 
source code that is used in building the ViewPoint product. This DDL source code is included 
in a file that is distributed with the ViewPoint product. The file named GDDL contains the DDL. 
Companion files—GTAL, GCOB, and GLNK—provide TAL, COBOL85, and SCREEN COBOL 
Linkage Section versions of the declarations. Once you have installed the ViewPoint 
application, these files reside on the ViewPoint Installation Subvolume.
