We quietly rolled out a new feature into the Brightbox control panel a couple of weeks ago, adding performance graphs for each of your Brightbox virtual machines. To view graphs for a virtual machine, click the “full details” link from the overview screen. You can currently choose to view CPU, disk i/o, public and private network usage for the last hour, day, week and month.

The graphing service is currently in beta, so you might find some occasional gaps in data for the time being, but over time this should prove a very useful feature.
