A code that uniquely identifies the message.
Message-text
Message-text is a text string describing the condition. This portion of the message sometimes contains detailed
information about the event, including terminal port numbers, network addresses, or addresses that correspond
to locations in the system memory address space. Because the information in these variable fields changes
from message to message, it is represented here by short strings enclosed in square brackets ([ ]). A decimal
number, for example, is represented as [dec].
