Log Files in Cloud Environment

When I looked at the login_audit log files in cloud i noticed it is has a new entry for every day. but the new entry is being generated at some random time. We have a scheduled process which runs at end of day collecting all the login info. I see entries in both the logs login_audit.csv and csv generated with current date. Any pointers on how this log file entries are created.

How does the expression_details.csv and sail_details.csv log files archiving works in Cloud. These log files are not accessible from left navigation, select Access System Logs link.
