>> If I turn on Log to Disk, how do I read the log while the server is running?
As long as it's a multi-user file (like TPS or whatever) it's fine to read and write at the same time - just like any table.
>> Name of the log file?
In the log folder, based on the date
>> Can I open it while the server is running to read it?
yes
>> How much it grows on disk?
depends on the traffic - the more the traffic, the faster it grows.
>> any automatic limit?
no. But it does start a new disk file every day.
>> do I need to shink or delete it?
presumably - depending on how much hard drive space you have. I would set a job to delete it once it was say 30 days old.
>> I am thinking on making an exe that reads that log to follow the server activity.
sure
cheers
