Measures reported by UspLunDetailsTest
Performance Monitor tracks LU paths to obtain statistics about I/O rates and transfer rates of these LU paths. If you analyze these I/O rates and transfer rates, you can detect LU paths through which a lot of I/O requests are made to the disk. You can also determine the LU paths through which a lot of data are transferred to the disk.
This test is used to obtain statistics about I/O rates and transfer rates at these LU paths.
The measures
