Blk_read/s
Indicatetheamountofdatareadfromthedriveexpressedinanum?
berofblockspersecond.Ablockisofindeterminatesize.
每秒读取的块数(可能报告的是个稍微和数据库内实际读取的有些差异,但大体上是准确的)
Blk_wrtn/s
Indicatetheamountofdatawrittentothedriveexpressedinanum?
berofblockspersecond.Ablockisofindeterminatesize.
同上,代表每秒写入的块数!
下面两个代表读取和写入的整个的块数!
Blk_read
Thetotalnumberofblocksread.
Blk_wrtn
Thetotalnumberofblockswritten.
