Has anyone figured out how to get mysql to backend rrd data so we could easily add and remove columns behind a 'device'. I have a few thousand devices. Ideally I would like to be able to store an arbitrary amount of DS's that can grow/shrink. Has this been done already? I saw a patch somewhere for rrdgraph to be able to pull from mysql by making a mysql fetch routine but has anybody done anything further? This would help out NetMRG in a big way.
