Re: [Nagios-users] Difference between % Total Time and % Known Time

2009-03-21 Thread Andy Shellam
Hi Ayotunde,

% known time is the amount of time that Nagios definitely knows the 
state of the hosts/services. For example if your Nagios system is down 
for an hour in a 24-hour period (or has no data from result checks to 
ascertain the state of devices) the % total time will be 100% (24 hours) 
but the % known time will be 95.8% (23 hours.)

That's how I understand it anyway.

 If reporting to “management” for example, which value should be reported?

 The staff in my monitoring unit (and myself :-) are a little confused 
 as to which of the two values represent availability for example.

 Thanks.

 Hi All,

 Please what’s the difference between % Total Time and % Known Time on

I could be completely wrong, but I've always thought total time
includes the time even before you started monitoring.  For example, if
you started monitoring something yesterday, but you run an availabilty
report for the last 30 days, the % total time might be only 3 or so
but the % known time might be 100.

I've always assumed % total time isn't very helpful, so would normally
only report %known time to management.

Cheers,

Jim
