Structure of the STRUCTURED-DATA element
STRUCTURED-DATA provides information in an interpretable and decomposable data format.
The following applications are possible, for example:
• More information about the syslog message
• Application specific information
STRUCTURED-DATA can contain one or more elements (SD-ELEMENT). Each SD element must
be enclosed in square brackets. If STRUCTURED-DATA consists of multiple SD elements, the
individual SD elements are separated by a space.
Each SD-ELEMENT consists of its name (SD-ID) and one or more name-value pairs
(SD-PARAM). Each name-value pair consists of a parameter name (PARAM-NAME) and the
associated value (PARAM-VALUE). A space separates the individual components (SD-ID and
SD-PARAM) within an SD element.
A CPU transmits the following SD ELEMENT in a syslog message, for example:

Structure of the MSG element
In the MSG (MESSAGE) element, a CPU transmits the simplified name of the event in English.
The following table shows what the content of a message of the MESSAGE element can look
like.
