9 Standard Events
Standard events are a small set of events that subsystems and applications should
generate to support operations management and conform with future enhancements to
these standard events. The small number of standard events improves many aspects
of event management.
This section describes standard events for anyone interested in using events to
manage NonStop systems, including:

Developers who generate EMS events in their subsystems and applications

Developers who write management applications and EMS filters

Operators who rely on EMS events to manage their systems
Each company—HP, third parties, and customers—should use this information to
determine the management functions and EMS events that its subsystems or
applications will support:

Subsystems that support a management function should, at a minimum, generate
the events that are needed to support that function.

Subsystems that comply with standard events should, at a minimum:

Follow the rules defined for all standard events.

Provide all the tokens defined for that event.

Use the standard EMS template defined for that event to display the event.

Subsystems that define their own events to support other management functions
should follow the rules for creating extensions to standard events.
To understand standard events, you need a basic knowledge of EMS, including the
concepts of EMS events, event tokens, how EMS events are collected and logged, and
the externals of EMS procedures such as EMSINIT, EMSADDTOKENS,
EMSADDSUBJECTS, and EMSGETTKN. This information is provided throughout this
manual and in the SPI Programming Manual.
