Servers - Resource Usage (Collectd)
CollectD & Graphite Server Metrics Dashboard with CPU, Memory, IO & Disk Stats, Network, NTP, and others 
This dashboard show you a in one row a short summary of your servers and you can deep dive into metrics organized by row.

It's based on "CollectD Server Metrics by Torkel Ödegaard" https://grafana.com/grafana/dashboards/24 but was adapted/improved with modifications in every graph.
