[hobbit] creating custom graphs in hobbit

[Adam Scheblein]

So i took your simpler way of getting the graph, however then i realized 
that the alerts that were being generated were still based on load -- is 
there any way to configure hobbit to turn red/yellow based on cpu 
utilization % rather than load?

thanks again for all your help, your dedication to OSS is inspiring!
