7.3.6 Datalogger
Header file: "DL_LogFile_handler.h" and "DL_dbus_handler.h"
These header files provide utility functions to handle the logger daemon.
7.3.6.1 Introduction
The datalogger TAF library functionality uses the ylog daemon to provide the opportunity to create static or
dynamic logging jobs.
Dynamic logging mode:
Each application can add variables that should be logged from the logging job. An application can define trigger
conditions for these variables that make the daemon write a new data record into the log-file.
Static logging mode:
A user created data logging configuration file (dlc) will be used.This file will be parsed by the ylogd. If no error
occurs while parsing, the data logger is ready for use. The used mode is determined over the ylogd
configuration file.
