| Log and trace message | A log and trace message contains all data and options to describe a log and trace event in a software. A log and trace message consists of a header and payload. |
| Dlt User | A Dlt User represents the source of a generated Dlt message. The possible users are SW-Cs, RTE (for VFB traces), DEM, or DET. |
| 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 | ECU IDis the name of an ECU, composed by four 8-bit ASCII characters (e.g., ABS0 or COMB). |
| Session | A session is a logical entity of source of log or trace messages. If an application / SW-C is instantiated several times, each instance gets a globally unique session ID with respect to the application / context ID. It is possible for an application / SWC to have several simultaneous log or trace sessions, if it has several ports opened to Dlt. Since Session ID is not specified in AUTOSAR for SW-Cs, the port defined argument values shall be used for this number. |
| Session ID | Session ID is the identification number of a log or trace session. |
| Application ID | Application ID is an abbreviation of an application / SW-C. It identifies the application / SW-C a log and trace message originates from. The Application ID is composed by four 8-bit ASCII characters. |
| Context ID | Context ID is a user defined identifier to group Log and Trace Messages generated by an application / SW-C. The following rules apply: - Each ApplicationID 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 “ApplicationID” and “ContextId”. Four 8-bit ASCII characters compose the ContextId. |
| Message ID | Messaged ID is the identifier to characterize the information, which is transported by the message itself. A Message ID identifies a kind of 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. |
| 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 send. |
| Log Channel | A physical communication bus, which is used to transmit Dlt messages. |
| External client | The external client is a tool to control, monitor, and store log / trace messages provided by ECUs using the Dlt module. |
