Unconditional and Conditional Tokens
•
A box contains a list of tokens that can appear in the event message. Header
tokens are included in the list because an event message can be filtered on these
tokens and other tokens. Tokens in an actual event message do not necessarily
appear in the same order that they are listed in the box.
•
The box also contains the event-message text.
•
A description for each token follows the box.
•
The recommended action describes what action should be taken.
Unconditional and Conditional Tokens
Tokens are grouped into two categories, unconditional and conditional:
•
An unconditional token is always present in an event message with a specific
subsystem ID and event message number. An example of an unconditional token
is ZEMS-TKN-EVENTNUMBER.
•
A conditional token is present only in the event message for certain cases. For
example, the token ZEMS-TKN-ACTION-NEEDED appears in an event message
only if the event message type is action-attention.
