Each log file is rotated once the log file reaches a size greater than 10KB. When the size limit
is reached, the old log is renamed to a new name containing the rotation number (such as
debug.log.1) and a new (blank) log begins with the default name. All rotated log files are
compressed (using gzip) after the second rotation except for the first log file (most recent). If
the file is compressed, .gz is appended to the log file name. This file is renewed each day at 4
a.m. Up to 30 files are saved for each type of log.
