RDK Logger

RDK Logger is a general-purpose logging mechanism for RDK components. It supports multiple log levels and modules, with log levels configured via a configuration file (debug.ini). Each module can have its own log level, and these can be changed at runtime using the provided CLI utility.

Features

• Abstracts logging client from underlying logging utility.
• Dynamically enables/disables logging level at run time.
• Provides a structured log format including timestamp, module name, log level, and message.
• Controls log level independently for each component/module.
• Enables logging globally via a single configuration value.
• Controls initial log level for each component/module from configuration file (debug.ini) at startup.
• Prints formatted data to stdout or log files.
• Supports separate log files for each module if configured.

Configuration

Logging levels and modules are configured in debug.ini. If a module is not explicitly configured in debug.ini, it inherits the log level from LOG.RDK.DEFAULT.

See debug.ini.sample for an example configuration file. The sample file includes comments explaining how to set log levels for each module and what each log level enables.

For example:

LOG.RDK.DEFAULT=WARNING
LOG.RDK.FOO=DEBUG
LOG.RDK.BAR=NONE

• The component FOO will print DEBUG, INFO, WARNING, ERROR, and FATAL messages
• The component BAR prints nothing
• All the other components prints WARNING and higher log levels like ERROR, and FATAL as defined by DEFAULT

Runtime Control

Use the rdklogctrl utility to change log levels for modules at run time.
