Yes.

No.

For the Service Log Entries section of the Availability report, nagios  
is just displaying all log entries related to that host/service that  
it finds. It's providing that information, and the duration between  
pairs of entries, in the event that information is useful to you and  
to provide you with the context for the Service State Breakdowns  
displayed above that section. The Service State Breakdowns section of  
the Availability report *is* aware of states and duration between  
states, not just log entries.  If nagios sees consecutive log entries  
with the same state, it knows that the service was in that state for  
the entire duration. For example, with log entries of --

1:00 OK
2:00 CRITICAL
3:33 CRITICAL
4:00 OK
5:10 OK
6:00 CRITICAL

Nagios would correctly report that the service was OK for 3 hours and  
CRITICAL for 2+ hours (ongoing) in the Service State Breakdowns  
section of the report.

Then you're probably not in a position to provide, and explain, the  
individual log entries to your manager. He shouldn't need or care  
about them though...

Yes, certainly. Provide him with the information from the Service  
State Breakdowns section of a specific service availability report or  
run the general Availability report for all services available from  
the main menu.
