Hello mmodestino! Thank you VERY much for your comment!
Fist of all, I run the search at the indexers and today's error list is the following:

Regarding index, I have just let the default. My main concern was to just see the events and search them; in a latter phase I would reconfigure indexes. When I search with index=main, I get nothing both on my 2 indexers and on my search head who is configured to implement distributed search.
When I run the command, I get the following:
Fordwarder1:

Regarding the deployment server's configuration, yes I have instructed to restart the forwarder. On top of that, I remember also restarting it manually...
Thank you very much again!
