Status Servers
You can customize the Network Status Summary screen to display other status items in
addition to the standard items. These can include information from subsystems you
write, such as information about the operation of automatic teller machines (ATMs).
They can also include information from Compaq subsystems, such as the batch
subsystem, that are not monitored by the basic ViewPoint application.
Status Servers
The ViewPoint application includes a server that collects data for the standard status
items. To allow the Network Status Summary screen to display information on
additional items, you can write one or more custom status collection servers, or status
servers, to augment or replace the work of the default Compaq status server.
When you write a status server, you should writer the server to be a standard Pathway
context-free server that is defined to the ViewPoint application or to another Pathway
system as a dynamic server class. You do not need to write the server as a process pair.
You can write the server in any language acceptable to Pathway, but your server can
use SPI only if you write it in TAL, COBOL85, or TACL.
A status server is identified by a server-class name, which is specified from the Status
Item Configuration screen. The standard status server delivered with the ViewPoint
product is installed with the server-class name ZVPT-STAT-COLL. Status servers you
write must have a different server-class name.
Server classes can be added to the Pathway application associated with the ViewPoint
application or they can exist in separate Pathway applications. The procedure for adding
a server class to the Pathway application associated with the ViewPoint application is
described in Section 7, Installation, Configuration, and Startup
.
The various processes involved in status collection are illustrated in Figure 6-7.
