Hi Florent,

thanks for your plugin :)

Reading the values from an RRD-file and store them in another seems a
bit hack-ish to me. However, the lighttpd-guys seem to have implemented
a `mod_status'-module which is almost identical to the one found with
Apache. From what I can see in their wiki the `apache'-plugin should
work with lighttpd, except `BusyServers:' which would need to be added
to the `apache'-plugin.

Yes, that's why I think it's hack-ish: Unless the RRD-file has a `LAST'
RRA you gen consolidated values and even if you get the plain values out
of a `LAST' RRA, you have the problem with `MIN' and `MAX'.

Would you mind giving the `apache'-plugin a try? Adding support for the
`BusyServers'-field shouldn't be a problem..
