dlt.conf - DLT daemon configuration file

The DLT daemon is the central application which gathers logs and traces from different applications, stores them temporarily or permanently and transfers them to a DLT client application, which could run directly on the GENIVI system or more likely on some external tester device.

The configuration file dlt.conf allows to configure the different runtime behaviour of the dlt-daemon. It is loaded during startup of dlt-daemon.

By default dlt-daemon loads the file /etc/dlt.conf. An alternative configuration file can be loaded with the option -c.

Daemonize

If set to 1 DLT daemon is started in background as daemon. This option is only needed in System V init systems. In systemd based startup systems the daemon is started by spawning own process. 

Default: 0

SendSerialHeader

If set to 1 DLT daemon sends each DLT message to the client with prepanding the serial header "DLS0x01". 

Default: 0

SendContextRegistration

If set to 1 each context which is registered from an application in the DLT daemon generates a message to inform the DLT client about the new context. 

Default: 0

SendMessageTime

If set to 1 DLt daemon sends each second a DLT control message to the client with the current timestamp from the system. 

Default: 0

ECUId

This value sets the ECU Id, which is sent with each DLT message. 

Default: ECU1

SharedMemorySize

This value sets the size of the shared memory, which is used to exchange DLT messages between applications and daemon. This value is defined in bytes. If this value is changed the system must be rebooted to take effect. 

Default: 100000

PersistanceStoragePath

This is the directory path, where the DLT daemon stores its runtime configuration. Runtime configuration includes stored log levels, trace status and changed logging mode. 

Default: /tmp

LoggingMode

The logging console for internal logging of dlt-daemon.

0 = log to stdout, 1 = log to syslog, 2 = log to file (see LoggingFilename)

Default: 0

LoggingLevel

The internal log level, up to which logs are written.

LOG_EMERG = 0, LOG_ALERT = 1, LOG_CRIT = 2, LOG_ERR = 3, LOG_WARNING = 4, LOG_NOTICE = 5, LOG_INFO = 6, LOG_DEBUG = 7

Default: 6

LoggingFilename

If LoggingMode is set to 2 logs are written to the file path given here. 

Default: /tmp/dlt.log

TimeOutOnSend

Socket timeout in seconds for sending to clients. 

Default: 4

RingbufferMinSize

The minimum size of the Ringbuffer, used for storing temporary DLT messages, until client is connected. 

Default: 500000

RingbufferMaxSize

The max size of the Ringbuffer, used for storing temporary DLT messages, until client is connected. 

Default: 10000000

RingbufferStepSize

The step size the Ringbuffer is increased, used for storing temporary DLT messages, until client is connected. 

Default: 500000

ContextLogLevel

Initial log-level that is sent when an application registers.

DLT_LOG_OFF = 0, DLT_LOG_FATAL = 1, DLT_LOG_ERROR = 2, DLT_LOG_WARN = 3, DLT_LOG_INFO = 4, DLT_LOG_DEBUG = 5, DLT_LOG_VERBOSE = 6

Default: 4

ContextTraceStatus

Initial trace-status that is sent when an application registers.

DLT_TRACE_STATUS_OFF = 0, DLT_TRACE_STATUS_ON = 1

Default: 0

ForceContextLogLevelAndTraceStatus

Force log level and trace status of context to not exceed "ContextLogLevel" and "ContextTraceStatus".

If set to 1 (ON) whenever a context registers or changes the log-level it has to be lower or equal to ContextLogLevel.

Default: 0

GatewayMode

If set to 1 gateway mode is enabled which means this ECU serves as gateway to forward messages from others. 

Default: 0

GatewayConfigFile

Read gateway configuration from another location. 

Default: /tmp/dlt-ctrl.sock /etc/dlt_gateway.conf

ControlSocketPath

Path to control socket. 

Default: /tmp/dlt-ctrl.sock

OfflineTraceDirectory

If this option is set, offline trace is enabled. This value sets the directory path to the offline trace memory. The directory must already exist. 

Default: Offline tracing is disabled.

OfflineTraceFileSize

This value defines the max size of a offline trace file, if offline trace is enabled. This value is defined in bytes. If the files size of the current used log file is exceeded, a new log file is created. 

Default: 1000000

OfflineTraceMaxSize

This value defines the max offline Trace memory size, if offline trace is enabled. This value is defined in bytes. If the overall offline trace size is excedded, the oldest log files are deleted, until a new trace file fits the overall offline trace max size. 

Default: 4000000

OfflineTraceFileNameTimestampBased

Filename timestamp based or index based.

1 = timestamp based, 0 = index based

Default: 1

PrintASCII

Prints each received DLT message from the application in ASCII to the local console. This option should only be anabled for debugging purpose. 

Default: Function is disabled

PrintHex

Prints each received DLT message from the application in ASCII to the local console. The payload is printed in Hex. This option should only be anabled for debugging purpose. 

Default: Function is disabled

PrintHeadersOnly

Prints each received DLT message from the application in ASCII to the local console. Only the header is printed. This option should only be anabled for debugging purpose. 

Default: Function is disabled

RS232DeviceName

If this value is set to a serial device name, e.g. /dev/ttyS0, a serial port is used for logging to a client. 

Default: Serial port for logging is disabled

RS232Baudrate

The used serial baud rate, if serial loggin is enabled. The RS232DeviceName must be set to enable serial logging. 

Default: 115200

RS232SyncSerialHeader

If serial logging is enabled, each received DLT message is checked to contain a serial header. If the DLT message contains no serial header, the message is ignored. 

Default: Function is disabled

TCPSyncSerialHeader

Each received DLT message on a TCP connection is checked to contain a serial header. If the DLT message contains no serial header, the message is ignored.

SendECUSoftwareVersion

Periodically send ECU version info.

0 = disabled, 1 = enabled

Default: 0

PathToECUSoftwareVersion

Absolute path to file storing version information - if disabled the DLT version will be send.

SendTimezone

Periodically send timezone info. 0 = disabled, 1 = enabled 

Default: 0

OfflineLogstorageMaxDevices

Maximum devices to be used as offline logstorage devices.

0 = disabled, 1 .. DLT_OFFLINE_LOGSTORAGE_MAX_DEVICES

Default: 0 (Functionality is disabled)

OfflineLogstorageDirPath

Path to store DLT offline log storage messages. 

Default: off

OfflineLogstorageTimestamp

Appends timestamp in log file name.

0 = disabled, 1 = enabled

Default: 1

OfflineLogstorageDelimiter

Appends delimiter in log file name, only punctuation characters allowed. 

Default: _

OfflineLogstorageMaxCounter

Wrap around value for log file count in file name. 

Default: UINT_MAX
