RE: [Nagios-devel] More Nagios bugs (minor)
Posted: Thu May 23, 2002 5:41 am
Good day,
Just try this out (the circular diagram with multiple parents), and you'll
see why this is actually a bug.
To better describe in words: imagine that I have a parent X, and host
children A through G. On the diagram, A through G will appear in a fan
arrangement around X. Now, imagine that I add another parent to children B
through F, such that they now appear fanned out from a different parent.
One would expect that hosts A and G would appear together now in the
diagram, but instead they appear in the same locations they did before, with
a lot of empty space between them where B and F used to be.
It's a bit hard to describe, but if you try it out yourself, you'll see
exactly what I mean.
Thanks again. I'll be sure to let you guys know if there is anything else
that I come across. =)

Just try this out (the circular diagram with multiple parents), and you'll
see why this is actually a bug.
To better describe in words: imagine that I have a parent X, and host
children A through G. On the diagram, A through G will appear in a fan
arrangement around X. Now, imagine that I add another parent to children B
through F, such that they now appear fanned out from a different parent.
One would expect that hosts A and G would appear together now in the
diagram, but instead they appear in the same locations they did before, with
a lot of empty space between them where B and F used to be.
