DLT - Automotive Diagnostic Log and Trace\r
\r
-Version: 2.3.0\r
+Version: 2.8.0 ALPHA\r
\r
+This component provides a standardised log and trace interface, based on the\r
+standardised protocol specified in the AUTOSAR standard 4.0 DLT.\r
+This component can be used by GENIVI components and other applications as\r
+logging facility providing\r
+- the DLT shared library\r
+- the DLT daemon\r
+- the DLT daemon adaptors\r
+- the DLT client console utilities\r
+- the DLT test applications\r
\r
-Introduction\r
-------------\r
+The DLT daemon is the central component in GENIVI, which gathers all \r
+logs and traces from the DLT user applications. The logs and traces \r
+are stored optionally directly in a file in the ECU. The DLT daemon \r
+forwards all logs and traces to a connected DLT client.\r
+The DLT client can send control messages to the daemon, e.g. to set \r
+individual log levels of applications and contexts or get the list of \r
+applications and contexts registered in the DLT daemon.\r
