How does intel advisor measure L1, L2 and L3 bandwidths for loops and functions? Are there PMU events which count the bytes transferred?

I am using the intel advisor cache aware roofline feature and wanted to know how intel advisor measures the Core to L1 data cache bandwidth of the application.

The application is run twice, once for collecting timing information for loops and functions and the second time with instrumentation. How is instrumentation used here to determine the Core to L1 bandwidth?
