Introduction to Standard Events
Introduction to Standard Events
This section describes events that subsystems and applications should generate to
support operations management on NonStop systems. Detailed content of each event
is specified as are the circumstances under which to generate the event, which EMS
template to use to display each event, and how programmed operators (management
applications) and human operators should use these events.
The set of standard events is derived from requirements of known existing
management applications. Subsystem and application developers can add their own
tokens to these standard events or define their own events to support additional
management functions. To ensure some consistency between the subsystem-defined
events and standard events, subsystem and application developers should use the
same framework in describing their management functions and follow the same
procedures in deriving their event content.
If your management decides to support standard events, adhere to all statements in
this section whenever possible.
These terms are used throughout this section:
Term Definition
Subsystem
application
Any program that generates EMS events.
Management
application
A program that uses EMS events to manage a NonStop system.
Program
operator
A program that performs management tasks usually performed by a human
operator. The term is interchangeable with management application.
Operator by itself refers to both human and program operators.
Management
function
A task performed by an operator or a function provided by a management
application to manage a NonStop system or network. A standard
management function is one supported by one or more standard events.
Standard
event
An event that contains all the tokens defined by the standard in this section
for that event—all required common tokens and all required event-specific
tokens. They could contain tokens defined by the subsystem or application.
Subsystem-
defined
event, private
event
An event defined by a subsystem or application, which should contain all
the common tokens defined for a standard event and any tokens defined by
the subsystem or application. Also known as standard-conforming events
because they can interoperate with standard events.
Nonstandard
event
Any other event, such as one defined prior to the establishment of standard
events. Nonstandard events typically do not have all the required common
tokens of standard events.
