Log and trace message	A log and trace message contains all data and options to describe a log and trace event in a software. The log and trace message consists of a header and payload.
Dlt User	A Dlt User represents the source of a generated Dlt message. Possible users are Applications, RTE or other software modules
Log Message	A Log Message contains debug information like state changes or value changes.
Trace Message	A Trace messages contains information, which has passed via the VFB.
ECU ID	The ECU ID is the name of an ECU, composed by 8-bit ASCII characters (e.g. "ABS0" or "InstrumentCluster").
Session	A session is the logical entity of the source of log or trace messages. If a SW-C / application is instantiated several times, a session for each instance with a globally unique session ID is used.
Session ID	The Session ID is the identification number of a log or trace session
Application ID	Application ID is the name (or the abbreviation of it) of a SW-C / application. It identifies the SW-C / application that log and trace message originates.
Context ID	Context ID is a user defined ID to group Log and Trace Messages generated by a SW-C / application. The following rules apply: * Each Application ID can own several Context IDs. * Context IDs are grouped by Application IDs. * Context IDs shall be unique within an Application ID. * The source of a log and trace message is identified using the tuple “Application ID” and “Context ID”. 8-bit ASCII characters compose the Context ID.
Message ID	Messaged ID is the ID to characterize the information, which is transported by the message itself. A Message ID identifies a log or trace message uniquely. It can be used for identifying the source (in source code) of a message and it can be used for characterizing the payload of a message. A Message ID is statically fixed at development or configuration time and is used in conjunction with the "Non-Verbose Mode" (see later).
Log level	A log level defines a classification for the severity grade of a Log Message.
Trace status	The trace status provides information if a trace message should be sent.
Log Channel	A physical Communications Bus which is used to transmit Dlt messages.
External client	The external client is a tool to control, monitor and store the log/trace information provided by the ECUs using the Dlt module.
string	For the Log and Trace Protocol a "string" defines a sequence of characters. Its length is either predefined by this document here, or there is a length specifier in front of it. The string contains only the character data for the text it represents without a special terminating item like the NULcharacter (\0).
Verbose Mode	When the Dlt module is sending out Log and Trace information onto the communication channel, the sent data message contains also predefined, static data elements like names, units, format information, length and so on;
Non-Verbose Mode	To reduce the network load on the communication channel, the Log and Trace data message contains as little of such metadata as possible. One of them is the Message-ID, which uniquely identifies this message and all of its content. All the above mentioned meta-data is handed over to the receiver via a separate extract file: together with the Message-ID, the receiver of a NonVerbose Mode message can reassemble the complete content, like sent in a Verbose Mode message.
