DEBUG Logs

...

• strace can give more debug information about containers:

...

•    RMFAPP can be used to verify rmfstreamer container.
     Example: play  http://192.168.2.68:8080/vldms/tuner?ocap_locator=ocap://0x125d

...

•    RDKBROWSER2 can be used to launch any URL.
     Example: systemctl enable rdkbrowser2.service
                     systemctl start rdkbrowser2.service - user can see the webpage in rdkbrowser2.
  
    If user wants to change URL, then we need to enter into this container and need to change rdkbrowser2.sh binary  as below:
    /usr/bin/lxc-execute -n RDKBROWSER2    -f /container/RDKBROWSER2/conf/lxc.conf – /bin/sh
    and then change /usr/bin/rdkbrowser2.sh file inside this container environment.
