Nagios has always used flat files for reporting (nagios.log and
archives/*) regardless of the backend status data storage method. The
database only ever contains current data, not historical.

This seems logical to me and is correct behavior. If the host itself
hasn't been down then the host has been available 100% of the time
irregardless of what services on that host are doing. I would expect an
availability report for the service to show the downtime for that
service. Under your assumption how would you represent the availability
of a host when one service has been up 100% of the time and another
service on the same host has been available 0% of the time. Would the
host availability be 50%? 0%? 100%? How about if there were 3 dozen
services on that host and only one has been down? Would that host be
considered unavailable?

It seems to be just a bad assumption. If I'm reading your e-mail
incorrectly, please elaborate more specifically.
