Retreiving Performance Graphs

I'm going to be making a C/ASP tool to monitor multiple load balancers on one page. Part of this will entail consolidating performance graphs from multiple devices. I'd be looking for a function to call to maybe get the graphs for CPU utilization, etc.. I was looking in the iControl SDK's API but I wasn't able to find something like this. It this possible?

 

 

Thanks,
