Looking for variables names that can be read via osmo-msc CONTROL interface

Dear osmocom-cni contributors,

I would like to retrieve (i.e. read or get) some data from a running osmo-msc from the CONTROL interface... but sorry, currently I cannot find either from the manuals or the source code the name of variables I can query.

Is there a mean to list all the variables that can be “GET” from the osmo-msc CONTROL interface? And… the list that can be “SET” through the osmo-msc CONTROL interface?

I am also interested in other osmo-cni nodes.

Thanks a lot in advance.

BR, Igor.
