event configuration file
event configuration file. A file that contains configuration information to control what
ViewPoint displays on an events screen. There can be any number of event
configuration files; operators specify on the Profile screen which file ViewPoint is to use
to display events at their terminals.
Event Detail screen. The ViewPoint screen on which selected event messages are
described in detail.
event log. A file or set of files maintained by the Event Management Service (EMS) to store
event messages generated by subsystems.
event management. The reporting and logging of important events that occur in a system
or network, the distribution and retrieval of information concerning those events, and
the actions taken by operations personnel or management applications in response to
the events.
Event Management Service (EMS). A software facility that provides event-message
collection, logging, and distribution facilities for the NonStop Kernel operating system.
It lets an operator or management application select conveniently from event-message
data and allows for flexible distribution of event messages within a system or network.
It has programmatic interfaces based on SPI for both event reporting and event
retrieval. See event message.
event message. The text intended for a system operator that describes a change in some
condition in the system or network, whether minor or serious. The change of condition
is termed an event. Events may be operational errors, notifications of limits exceeded,
requests for action needed, and so on. Each event message, when displayed on an
event screen, is displayed as one line of text.
Extras. A SCREEN COBOL program unit that a programmer can add to the ViewPoint
application, possibly as a means of invoking a larger set of program units that you
supply. The ViewPoint application calls the Extras program unit (which must have the
name EXTRAS) when the user presses the Extras function key.
File Utility Program (FUP). The Compaq interactive utility that lets you perform a variety of
operations on files.
filter. A file that contains a list of criteria against which incoming event messages can be
compared so as to pass a given message (if it meets all criteria) or not pass it (if it fails
one or more criteria).
filter object file. A file containing the compiled filter code that determines which events are
displayed on an events screen.
forwarding distributor. An Event Management Service (EMS) distributor process that
sends selected event messages to an EMS collector on another network node or, if the
node has multiple collectors, to an EMS collector on the same node. Compare
consumer distributor and printing distributor.
