Every Sunday at midnight, /etc/log/sis is moved to /etc/log/sis.0; /etc/log/sis.0 is moved to /etc/log/sis.1; and so on. The suffix can go up to 5, so the old /etc/log/sis.5 will be deleted. SIS activities are saved for a total of seven weeks.
Each entry of the /etc/log/sis file is a single line containing
the following space-separated fields.
