man iostat后。。发现这2个数字是以块为单位的读写统计。。
tps
Indicate the number of transfers per second that were
issued to the device. A transfer is an I/O request to the
device. Multiple logical requests can be combined into a
single I/O request to the device. A transfer is of inde-
terminate size.
Blk_read/s
Indicate the amount of data read from the drive expressed
in a number of blocks per second. Blocks are equivalent
to sectors with 2.4 kernels and newer and therefore have
a size of 512 bytes. With older kernels, a block is of
indeterminate size.
Blk_wrtn/s
Indicate the amount of data written to the drive
expressed in a number of blocks per second.
Blk_read
The total number of blocks read.
Blk_wrtn
The total number of blocks written.
