## Logging
For debugging purposes, users can control the ROS wrapper log level and also the SDK log level.
* ROS wrapper log level - set the parameter `log_level` in the ros2 launch command or in the launch file itself
e.g. `ros2 launch realsense2_camera rs_launch.py log_level:=warn`
* LibRealSense2 SDK log level - export the environment variable called `LRS_LOG_LEVEL` and set it to the desired log level.
e.g. `export LRS_LOG_LEVEL=debug`
