how to change default logging verbosity
Using ROS2 when running a launch file it always start like this:
[INFO] [launch]: All log files can be found below
[INFO] [launch]: Default logging verbosity is set to INFO
Is it possible to change this default verbosity?
I know that it is possible to change a Node execution verbosity using this:
--ros-args --log-level
but what about the default verbosity when running a launch file? I cannot changed it from INFO
Thank you!

Please check out these:
https://answers.ros.org/question/311471/selecting-log-level-in-ros2-launch-file/
https://docs.ros.org/en/humble/Tutorials/Demos/Logging-and-logger-configuration.html# + https://github.com/ros2/demos/tree/humble/logging_demo, this part is the most interesting one
E.g. for Foxy
launch_ros.actions.Node(
package='demo_nodes_cpp',
executable='talker',
output='screen',
arguments=['--ros-args', '--log-level', 'debug']
)

Thank you for your response, this is actually what I am doing and i can set the logger of the node I am executing. However what I can't change is the default [INFO][launch] messages that appear when running a launch file.
For example, if you make a new ros2 package which cointains only the follwing launch file:
from launch import LaunchDescription
from launch_ros.actions import Node
def generate_launch_description():
return LaunchDescription([
Node(
package='teleop_twist_joy',
executable='teleop_node',
name='teleop_twist_joy_node',
arguments=['--ros-args', '--log-level', 'fatal']),
Node(
package='joy',
executable='joy_node',
name='joy_node',
arguments=['--ros-args', '--log-level', 'fatal'])
])
You still get the following output:

[INFO] [teleop_node-1]: process started with pid [13112]
