Why we need notifications?

  • To ensure that the value is set properly and updated in the database.

Module and component

  • Logging Mechanism: RDKB Logger
    The RDKB logger is linked to RDK-B modules to enable component-wise logging.
  • Component Responsible for Enabling/Disabling Notifications
    • By default, the system will look for /etc/debug.ini.
    • rdklogctrl can be used at runtime.

During Boot-up 

  • When the RPi boots up, each RDK-B component will be initialized, which in turn will initialize the logger and start logging into the corresponding log file, depending on the log level set for the component in /etc/debug.ini

How enable/disable notifications works?

  • Notifications are enabled by default, and the levels can be referred to in /etc/debug.ini.
  • Using rdklogctrl, we can disable the logs from any module integrated with rdklogger

Notification levels 

  • ./etc/debug.ini
  • rdklogctrl <app_name> <module_name> <loglevel>
    1. To add a new log level - dklogctrl CcspWifiSsp LOG.RDK.WIFI DEBUG
    2. To remove the existing Log level - rdklogctrl CcspWifiSsp LOG.RDK.WIFI ~DEBUG
  • The default log levels set for components are FATAL,ERROR,WARN,NOTICE,INFO.
  • Log levels can be controlled independently for each module.

Examples

Changing SSID name

  • Default SSID

root@RaspberryPi-Gateway:~#  dmcli eRT getv Device.WiFi.SSID.1.SSID

Execution succeed.
Parameter    1 name: Device.WiFi.SSID.1.SSID
               type:     string,    value: RPI_RDKB-AP0

  • Module: Onewifi . By default, the logs are enabled with below log levels

LOG.RDK.WIFI = FATAL ERROR WARNING NOTICE INFO
