Hi Marc

Yes you are completely right!

 I had referred to a plug-in synopsis which had put the Interval setting
within the <plugin ..> block .
 As you say the Interval needs to be added by creating a block for the
loadplugin section i.e. <LoadPlugin cpu>... I tried this for cpu ethstat
etc and now works as expected.

I should have read the synopsis in the manpage for collectd.conf more

Many Thanks
