      Hello Nick, Thanks again for giving me lots of tips on using
      Cfengine. I learn about it every day! I will once again
      follow your recommendations and split the promise into
      several bundles to respect your advice.

Great, glad that it helps!

I guess before you head down that path too far, I should also point out
the `host_info_report' in the MPF. Were you aware of it? The bundle is
not run automatically by default, but it's there for use, you could call
it from your policy with a /methods/ type promise, you could modify it
to your needs (but that introduces a maintenance burden), or you could
use it for inspiration in building something similar for yourself.

      Actually I need to transfer a lot of data (ip, hostname,
      version of software etc... ) automatically from my cfengine
      clients using files, for inventory for example. I am using
      the Reports function. I create a file on my client which I
      then transfer via SCP to a directory on another resource.

      Is it the best solution or do you advise me to use another
      function?

Well, I am glad you asked. First, I am of course bias, but, I think
CFEngine Enterprise is the /best/ solution for this. You don't have to
do anything special, you just get centralized reporting. As far as
continuing down the path you are on, I would nudge you away from using
the /reports/ type promise for what you are doing. At least as best I
can tell, a files type promise to manage the full content of a file
would be much more straight forward and appropriate for your use case. I
think reports promises to a file are more appropriate for logging.
