Ok, so what's so hard about that?  All you need is a simple rrdtool plugin
then, right?  Plugin only has to check for staleness of the data and return
it if it's not stale.  With the exception of ping time (which, btw, cacti
gets wrong on redhat7.2 and later - those are microseconds, not
milliseconds) the type of data I would typically put into rrdtool isn't the
kind of data that nagios is monitoring.  I use nagios to monitor
availability; I use mrtg/rrdtool to monitor performance.

For all I know there may already be an rrdtool plugin for nagios - if there
isn't, it seems like it would be a simple ten minute project.

That's actually what I was eluding to below in my response.  I don't believe
the front end is what is needed.  The backend.  Once you have either mysql
or native rra database, you can do magic.

The actual front end doesn't matter all that much.  It would be relatively
trivial to put that together.  Once the backend is all squared away.

What I would like to do (and one day may write) is to have Nagios be center
piece (and beautiful it is) collecting all information into a database.
This information would be then sorted and stored in db.  From that point on
with Perl and PHP write a interface that graphs and allows management type
to see all the pretty UHHH AHHH graphs that seem to make their day.

With this you could have graphs for almost every darn lil' thing you want,
especially if at the same time you include Snort graphs as well as Ulog
iptables accounting.

All in one nice package.

from time to time this debate comes up. It usually devolves into everyones
favorite implementation of a RRDtool front-end.

I am not above this. I prefer Cricket. Some people prefer using APAN. APAN
is cool. Cricket is cool. I don't know cacti.

Inevitably these seem to be arguments about front-ends. If Nagios polled the
backend (rrd) then we would avoid having arguments about cacti vs cricket vs
APAN etc. Then everyone would have their preferred method sorted.

see here for a gmane based thread.
