How to see all parameters in the parameter server ?

edit

Thanks for answering me. The problem is that the parameters exists in the source code of the planner. You can find it here: http://docs.ros.org/indigo/api/eband_...
I want just to be able to read and modify them from param server

In your example, the node tries to read the parameters server, if they exist they are read from the parameterserver, otherwise a default value is taken. But that default value is not set in the parameters server. In resume, the parameter did not exist and it does not exist yet after the getParam

If you want to set those parameters you have to do it previously to the initialization of your node, you can use a roslaunch file to change those values. If you set in a launch file a parameter it will work.

Another thing that you may be not taking into account is that the parameter server is a totally diferent mechanism to the dynamic_reconfigure properties. getParams get parameters from the parameter server (let's say the roscore)... the dynamic reconfigure client gets parameters from the target node

the eband local planner does not use the dynamic_reconfigure mechanism, so you will not be able to read any data with the rqt_reconfigure app. parameters cannot be updated in runtime. Instead, they are only read once at the node start from the parameter server using the getParam method

Ok, thank you for your answer. But I still have a misunderstanding. Usually, when I load parameter from a YAML file, they appear in the parameter server even if they are useless. And I don't understand why they doesn't appear with the eband_local_planner.

A yaml file is just a file, those parameters are not loaded into the parameter server except if they are explicitly loaded. There are two ways to load a yaml file... trough the "rosparam load" command and through a launchfile. http://wiki.ros.org/roslaunch/XML/ros...

Yes obviously, I load it from a launch file, it was implicit
