How I can wrote to log only information what I see when uploading, for example

Even Loglevel = 1 give to me huge information. I want to save to file only information that I see on console.

Consider using XML logging:

You can filter that any way you want, e.g. using XSLT:

Thank you for the answer. I tried to use XML Group, but I don't understand why group name without first word.
For example, for command: "synchronize remote -delete -criteria=either -permissions=0644".. I see: "remote -delete -criteria=either -permissions=0644" and so on.

Why I can get this mistake?
