NAME

dlt-system.conf - DLT system process configuration file

DESCRIPTION

The DLT system logging process is the central application, which logs system information from the platform. It provides the features filetransfer, syslog adapater, logging of any kind of files and procfilesystem logger. The individual features can be enabled and disabled in the configuration file.

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

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

GENERAL OPTIONS

ApplicationId

The application Id used for the dlt-system process.

Default: SYS

SHELL OPTIONS

ShellEnable

Enable the Shell for command line injections. Be careful when you enable this feature. The user can send any kind of shell commands. The commands are executed with the rights of the dlt-system process. Dlt-system is started by default as user covesa.

Default: 0

SYSLOG ADAPTER OPTIONS

SyslogEnable

If this option is set to 1, the syslog adapter feature is enabled. SyslogPort needs to be configured too if Syslog is enabled.

Default: 0

SyslogContextId

This value defines context id of the syslog adapter.

Default: SYSL

SyslogPort

This value defines the UDP port opened for receiving log messages from syslog. Configuration for syslog to forward log to this port is necessary. Adding this config *.* @localhost:47111 in config file of syslog (usually in /etc/rsyslog.d/50-default.conf) and restart the syslog service by command “sudo systemctl restart rsyslog.service”.

Default: 47111

SYSTEMD JOURNAL ADAPTER OPTIONS

JournalEnable

Enable the Systemd Journal Adapter. This feature is only available, when dlt is compiled with the option “WITH_SYSTEMD_JOURNAL”. Dlt-system is started by default as user covesa, see dlt-system.service file. The user covesa must be added to one of the groups ‘adm’, ‘wheel’ or ‘systemd-journal’ to have access to all journal entries.

Default: 0

JournalContextId

The Context Id of the journal adapter.

Default: JOUR

JournalCurrentBoot

Show only log entries of current boot and follow. If JournalCurrentBoot and JournalFollow are not set all persistent journal entries will be logged.

Default: 1

JournalFollow

Show only the last 10 entries and follow.

Default: 0

JournalMapLogLevels

Map journal log levels to DLT log levels.

- 0       Emergency     DLT_LOG_FATAL

Time in seconds after startup of dlt-system when first file is transfered.

Default: 0

FiletransferTimeoutBetweenLogs

Time in seconds to wait between two file transfer logs of a single file to DLT.

Default: 10

FiletransferDirectory

LogFileFilename

This value sets the full filename path to the file, which should be logged.

LogFileTimeDelay

This value is used in mode 3 and defines the number of seconds, after which the defined file is logged.

LogFileContextId

This value defines the context id, which is used for logging the file.

LOG PROCESSES OPTIONS

LogProcessesEnable

Enable the logging of processes. 0 = disabled, 1 = enabled

Default: 0

LogProcessesContextId

Default: 0

LogProcessTimeDelay

This value is used in mode 3 and defines the number of seconds, after which the defined procfilesystem file is logged.

Default: 0
