sar -b reports much high volumes of I/O than some other utilities
Issue
- compared the output of a "sar -b" command with the I/O report produced by other 3rd party tools and sar reports 5 times as many I/Os in MB/s, why?
- why are sar -b tps values much higher than when summing the non-partitioned sdN disks in iostat -x?
- is there a way to exclude specific devices from sar -b output?
Environment
- Red Hat Enterprise Linux 5
