AXI performance monitor byte count - With or without valid ready handshake?

Hello,

 

I was reading the AXI performance monitor product guide and trying to understand the mechanics of the metrics counters.

 

When the read/write bytes are counted, are they counted as the ones with a valid/ready handshake? Do metric counters only include valid data?

 

This line on page 12 made me doubt if the valid/ready handshake is accounted for: "System-level metrics like write data throughput, read data throughput... can be computed by obtaining all metrics for all the agents in the system."

The document is ambiguous and the string "handshake" is found nowhere.

 

Thanks in advance.
