How do I tell the ros2 daemon to log to stdout?
How do I tell the ros2 daemon to log to stdout?
I know about ROS_LOG_DIR
(https://wiki.ros.org/ROS/EnvironmentVariables#ROS_LOG_DIR), but that doesn't help. If there were a ROS_LOG_FILE
, then I would have tried setting it to /dev/stdout
.
Here's an Amazon person talking about it (https://discourse.ros.org/t/ros2-logging/6469), but that conversation seems more like a wishlist than a spec.

the ROS 2 daemon is for .. ROS 2.
The wiki you refer to documents ROS 1 environment variables. That won't help with configuring the daemon.
Afaik the only way to get it to output anything is to enable debug mode using the --debug
option (otherwise all output streams are set to /dev/null
):
$ ros2 daemon start --help usage: ros2 daemon start [-h] [--debug] Start the daemon if it isn't running optional arguments: -h, --help show this help message and exit --debug, -d Print debug messages
it'll still detach though, so I'm not sure where messages following the ones printed during initialisation go.
