[collectd] quick reload

[Andrés J. Díaz]

Hi!

As fas as I known, there is no way to reload configuration without
restart the daemon, but I think you can use rrdcached instead of
rrdtool plugin (http://collectd.org/wiki/index.php/Plugin:RRDCacheD).
Unfortunately rrdcached is not available in latest rrdtool stable
tarball, you need to compile rrdtool from subversion branch. With
rrdcached you do not need to flush the data to disk when restart the
collectd daemon (rrdcached keep data in memory and flush when needed).

I use collectd with rrdcached from few months with good results, but I
have only ~20 rrds per host.

I hope to help you.

Regards,
  Andres
