18 Distributor Event Messages
This section describes event messages generated by printing or forwarding distributors
and are related to their operation. (Consumer distributors do not generate event
messages.)
Distributor event messages help you monitor and manage network resources from a
ViewPoint console or through an application. Two examples of distributor events that
require operational attention are a bad log file or a bad printer destination (for a print
distributor).
The type of distributor determines, to some extent, which events cause the generation
of an event message. For example, when a printing distributor cannot send event-
message text to a print device, it generates an event message. Similarly, when a
forwarding distributor cannot send an event message to a collector, it generates an
event message. A consumer distributor reports its problems through an error list
returned to the controlling application. Therefore, consumer distributors generate no
event messages.
Certain distributor event messages are critical (their ZEMS-TKN-EMPHASIS tokens
are set to ZSPI-VAL-TRUE). An event that threatens an event-message source—such
as the destruction of a log file or the failure of a collector to deliver its event
messages—triggers a critical event message.
Many distributor event messages are not critical but require some response from the
operations environment. In addition, some event messages are only informative.
