Well, it's pretty. It's probably great if you have one to five machines you care about, or you really want a pretty dashboard.<p>Notable features that I would need all relate to multi-server usage:<p>- central config across hosts<p>- alerting when values go over or under thresholds<p>- a mode for automatically selecting and viewing the machines which are working hardest, or not working<p>- a mode for viewing of a few stats across all machines<p>- a mode for slide-show viewing of a few stats across all machines
