Sign up for a free GitHub account to open an issue and contact its maintainers and the community. But for dashing, you can use the following syntax: This will set the log level to debug for every node being run in this process (rcl, rclcpp, the rmw layer). If not, I'll take a look at them. privacy statement. ROS2 allows you to run individual nodes with the command: $ ros2 run <package_name> <node_name> This is nice and fun if you are just running a couple of nodes at the same time, but imagine you need to run 10-20 nodes like this. When I launch my node, I get a prompt that looks like this: Does rclcpp have a way to get this folder name /home/swaroophs/.ros/log/2020-06-11-11-23-16-455437-swarooph-xps-16567 ? privacy statement. This file will hold the ROS2 global parameters we want in the application. Feel free to continue the discussion afterwards. This may be due to components having their own configuration separate from that of the container (see here). <remap> Set a remapping argument for this node. If I run in a shell the logging is working as expected. In ROS1 launch files were implemented in XML. Cannot specify log level via the CLI rosbag2#288.

There are quite a few open bugs in this area: Is anyone currently working on these? Then we will discover launch actions, event_handlers, substitutions and conditions in more detail. From there, we can determine what pieces we have and what is missing. Instead, you can use a so-called launch file. Or did I miss some other option to troubleshoot my setup?

How to get a ROS 2 node's log folder/file. In the future there will be a generalized approach to external configuration of loggers at runtime (similar to how rqt_logger_level in ROS 1 allows logger configuration via remote procedural calls).
