[collectd] Help setting up rrdcached

[Daniel.]

I have a virtual machine with shares its virtual disk with another VM,
so I got a real slow virtual disk. I need to improve performance,

I can't get rrdcached plugin working. I'm facing this error:
rrdcached plugin: rrdc_stats_get failed with status 107.

Also I see that rrdtool has almost same funcfunctionality in rrdtool
plugin, so will rrdcached worth in this case?

Cheers!
