Introduction

RDK logger is a general purpose logging mechanism which is used for logging in RDK-B. Internally this uses log4c for formatting and supporting multiple log levels for different modules. The log level for each component is read from a configuration file debug.ini (rdkb_debug.ini) during component initialisation. Logger is implemented as a shared library and components need to link this library in order to  include logging functionality.

RDK logger is linked to RDK-B modules to enable component wise logging. When the unit boots-up, each RDK-B component will be initialised which in turn will initialise logger and start logging into the corresponding log file depending on the log level set for the component.

Note: The RDK data model naming convention prefix was changed in March 2020 to “X_RDK_”. We request you use this new prefix going forward.

Architecture

1. All logs from modules (CcspTraceError, CcspTraceInfo, etc..) are routed to RDK logger library. RDK logger logs these into log files based on module wise LogLevels & LoggerEnable options.  RDK  logger uses log4c library internally to achieve the functionality.
