<br>
As fas as I known, there is no way to reload configuration without<br>
restart the daemon, but I think you can use rrdcached instead of<br>
rrdtool plugin (<a href="http://collectd.org/wiki/index.php/Plugin:RRDCacheD" target="_blank">http://collectd.org/wiki/index.php/Plugin:RRDCacheD</a>).<br>
Unfortunately rrdcached is not available in latest rrdtool stable<br>
tarball, you need to compile rrdtool from subversion branch. With<br>
rrdcached you do not need to flush the data to disk when restart the<br>
collectd daemon (rrdcached keep data in memory and flush when needed).<br>
<br>
I use collectd with rrdcached from few months with good results, but I<br>
have only ~20 rrds per host.<br>
<br>
I hope to help you.<br>
<br>
Regards,<br>
Andres<br>
