The nfs_hist command shows e.g. the number of reads that get serviced with a specific response time:
v3 read: 4817066 (blocking requests) - millisecond units 0 1 2 3 4 5 6 7 4144583 475420 86036 25125 16078 11301 9468 6301
What is the exact range for e.g. "0"? I would expect it to be between 0 and 1 ms and not exactly 0 ms. Can someone confirm this?
And another question about the "lun hist" command. What is the difference between scsi_write and scsi_write_extended?
