// This section affects kea-dhcp4, which is the base logger for DHCPv4 component. It tells
// DHCPv4 server to write all log messages (on severity INFO or higher) to a file. The file
// will be rotated once it grows to 2MB and up to 4 files will be kept. The debuglevel
// (range 0 to 99) is used only when logging on DEBUG level.
