according to the following experience, we would need to support

• --ros-args option.
• individual log level for each node.

any comments and thoughts?

# ros2 run rclcpp_components component_container --ros-args --log-level debug

this works but all nodes will set the same log level with container.

# ros2 component load /ComponentManager composition composition::Talker --ros-args --log-level debug
usage: ros2 [-h] [--use-python-default-buffering] Call `ros2 <command> -h` for more detailed usage. ...
ros2: error: unrecognized arguments: --ros-args

expected this would work, but it does not support --ros-args option.

# ros2 component load /ComponentManager composition composition::Talker --log-level warn

problem can be observed in mainline.

I think the best way to go is to align to the ros2 run command syntax.

I wouldn't open it as a BUG if it wasn't listed in the command help syntax.. I spend 2 hours trying to understand what am I doing wrong, because if it listed in the help it should work :)

ros2 component load --help

                           [--log-level LOG_LEVEL] [-r REMAP_RULES]

@Nir-Az okay it seems that already have an option for log level, but it does not work. (i misunderstood.) this behavior is the same with mainline.
