How to prevent realsense from show these logs

[5730289021-NN]

Greeting everyone, may I have some little help here

My launch file is

<launch>
    <include file="$(find realsense2_camera)/launch/rs_camera.launch">
        <arg name="filters"             value="pointcloud"/>
        <arg name="depth_width"         value="640"/>
        <arg name="depth_height"        value="480"/>
        <arg name="enable_depth"        value="true"/>
        <arg name="clip_distance"       value="2.5"/>
	    
        <arg name="color_width"         value="640"/>
        <arg name="color_height"        value="480"/>
        <arg name="enable_color"        value="true"/>

        <arg name="enable_fisheye"      value="false"/>
        <arg name="enable_infra1"       value="false"/>
        <arg name="enable_infra2"       value="false"/>

        <arg name="device_type"         value="d435i"/>

        <arg name="depth_fps"           value="15"/>
        <arg name="color_fps"           value="15"/>
    </include>
</launch>

and now the launch file emitting logs like

 29/04 19:46:08,668 WARNING [140540339263232] (uvc-device.cpp:664) interrupt event received: 1, 3, 0, 7, 0, 13, 
[ WARN] [1588164368.882269952]: Hardware Notification:USB CAM overflow,1.58816e+12,Error,Hardware Error

How could I edit my launch file to suppress that?

You could try using output="log"

This should send warnings to a log file in $ROS_HOME/log instead of the screen.

Somebody who tried this said that it hid the WARNING messages, though ERROR and FATAL type messages continued to be displayed onscreen.

If there is a warning / error message though then it is recommended to try to diagnose and correct it instead of hiding it.

It is unusual though that you are receiving 'USB CAM overflow' messages when using a low resolution and FPS speed like the ones defined in your launch file.

Thank you for the solution. I thought it was normal to get those message since there were tons of them when I ran the launch file.

[MartyG-RealSense]

No, it's not normal. It suggests that something is overwhelming the USB port with data.

Someone who had the same problem when using the camera on a USB2 port resolved it by disabling the infrared streams by adding the instructions below to the roslaunch statement.

enable_infra1:=false enable_infra2:=false

I see, I'll figure out on that.
Furthermore, the output="log" can only be defined within node tag like <node name="listener1" output="log" /> but I think from this library structure it's better to manipulate within include tag or launch tag. I don't think putting inside here is a good idea

Good luck! Please feel welcome to come back to the RealSense ROS forum any time that you need to.

Any idea on fixing the launch tag without adding “output” attribute to the <node> element directly?

The simplest methods that I could find to disable all logging are in the link below:

Alright, thank you
