4.How can I use some kind of bfgminer record? to be able to see what happend like 3 or 5 hours ago (errors, restarts, block finds...). I know what letters means but I want to see it as some
kind of data file with all details through the time like I see it live on monitor. Is it even possible?
There are several possibilities to do it. Use -h as parameter for bfgminer, watch out for "log". Choose the ones suitable for you.
