Use Diagnostics aggregator node with other topic names #300

Closed rebeccaRossRobotics closed 1 year ago

rebeccaRossRobotics commented 1 year ago

Hi!

I have multiple topics which have a msg type of diagnostic_msgs/msg/DiagnosticArray. Is there a way to get the diagnostics_aggregator node to listen to them?

I have tried to remap one back to be on the /diagnostics topic but nothing is piping back to /diagnostics. Here is the code I have for starting the aggregator node and remapping.

diagnostic_aggregator_node = Node(
        package='diagnostic_aggregator',
        executable='aggregator_node',
        remappings=[("/diagnostics_cyphal", "/diagnostics")],
        parameters=[diagnostic_aggregator_config_file],
    )

Thanks!

All diagnostics messages should be published in the \diagnostics topic. Otherwise, the remapping strategy would be also my best bet. But I have never worked with topic remapping in ROS2, so I can not help you there.
