I tried getting mrtg to work with rrdcached but it uses updatev in the rrdtool v1.2+ code path so it doesn't work. Looking through the code it seemed like there was no reason why if we forced the old 1.1 path it wouldn't work just fine.
Thought it was worth a shot so tried it, and it works great!In fact it works better than great, it transformed out stats machine from a totally unusable box, due to excessive io, back
to what it was before we started running mrtg on it :) Given this I thought I'd share this experience, so others can benefit. The patch attached is what we changed, its pretty rough with the cache server hard coded but it would be easy to fix that and works ;-) Hopefully future version of rrd will add updatev support to cached so this isn't needed but in the mean time we're just really happy to see the massive improvement that this new version brings, so thanks to everyone who worked on it!
