Nice, it's working.
But I see it's not working when using the weathermap (it can't read the last rrd values anymore so all links are shown as « 0 »).
Have you any idea of workaround for this ? I tried to reduce a lot the timers but I completely lost the performance advantages (weathermap is generated every 5 minutes in my setup)

Nice stuff. There is some interesting reading here on tuning dirty writes - https://code.google.com/p/epicnms/wiki/Scaling

There was some discussion on IRC the other day about rrdcached and how it can be used with Observium to reduce your storage IO a lot when polling a huge amount of interfaces. However, not a lot of documentation exists yet on how to get rrdcached to work with observium. I did some trial and error and found a working method and wrote a quick and dirty guide. You can find it here: http://blog.best-practice.se/2014/10/using-rrdcached-with-observium.html Feedback is highly appreciated!
