[dnsdist] format logAction Rows

[Lichtnau Frank]

Hi,

I'am new here and I have 2 questions:

1. Is it possible to search in old threads whithout download all topics from Archiv or can I download all threads in one?

2. I use dnsdist from buster V1.3.3 and I need a datetime in the LogAction file. 
    The documentation says, I can modify the message before it will be written.
    I need a LUA function for that. But I don't know LUA. Has anybody an exemple for me?

thanks
Frank
