Hi everyone,
I have a quick question for everybody, does anyone use colletcd+rrdcached?Because I tried to setup the rrdcached pluding to stop using rrdtools plugin but when I do so the server is just under heavy IO load. Normally with rrdtool plugin the load is about 2-3 (See the attachment).
But when I try to activate the rrdcached the server is just unusable, the load is about 25 (for a 16 CPUs) but I have something like 30% of IO wait.
Everything is on debian squeeze: collectd(4.10.1-1+squeeze2)/rrdcached(1.4.3-1)
Any idea why something that is supposed to reduce load is dramatically increasing it?
