Nagios availability & % Time Undetermined

[Darren Gibbs]

I have a Nagios setup currently monitoring one host, with serveral services.

One of those services is ping {check_host_alive}, which shows green if the
host is up no problems.

However, when I attempt to access the "Availability" reports from the menu
and select the individual host, I get something like this

State Type / Reason Time % Total Time % Known Time 
UP 		Unscheduled 0d 7h 31m 28s 4.479% 98.869% 
		Scheduled 0d 0h 0m 0s 0.000% 0.000% 
		Total 0d 7h 31m 28s 4.479% 98.869% 
DOWN 		Unscheduled 0d 0h 5m 10s 0.051% 1.131% 
		Scheduled 0d 0h 0m 0s 0.000% 0.000% 
		Total 0d 0h 5m 10s 0.051% 1.131% 
UNREACHABLE Unscheduled 0d 0h 0m 0s 0.000% 0.000% 
		Scheduled 0d 0h 0m 0s 0.000% 0.000% 
		Total 0d 0h 0m 0s 0.000% 0.000% 
Undetermined Nagios Not Running 0d 0h 0m 0s 0.000%  
		Insufficient Data 6d 16h 23m 21s 95.470%  
		Total 6d 16h 23m 21s 95.470%  
 
All Total 6d 23h 59m 59s 100.000% 100.000% 

The high percentage of "Insufficient data" had got me baffled.

Nagios is, as far as I can tell, checking the box fine. The checks run every
5 minutes, I get notified if anything breaks, everything else looks fine - I
can't figure out why this list is reporting so much undetermined time.

Any clues? ANyone know how to erase these total figures, maybe, and start
again from scratch?

Thanks.
