Nagios numbers useless

[Mike McClure]

Hi Björn,

Sorry to hear you are confused.  Maybe I can help explain it.

For the reporting, a host can be either in a state that Nagios knows about (Up,
Down, Unreachable), or it can be in a state that Nagios does not know about
(Undetermined).

The percentages *not* in parens are absolute, that is, the percentage of time for
the period that the host was in each of the 4 states.

Now, you might only care about the time that the state was able to be determined,
i.e., Up, Down, or Unreachable.  That is what the percentages in parentheses are
for.

In other words, for the time period given, when Nagios was able to determine what
the state of the host, what are the percentages of the time that the host was Up,
Down, or Unreachable.

Make sense?
