Yes, sar -A works and gives me some good information but when I run sar -d, its not giving me any information except for "Requested activities not available". What is going on here. I am getting really confused as to what is going on here. POints will be assigned.

Looking at the source

http://snupi.sdsc.edu/Software/sar.c

Itlooks to me that the data isn't available in the collected data file. I would look at how youa re calling "sadc"

Sometink is wrong also with the output of iostat command

it should read something like

Device: tps Blk_read/s Blk_wrtn/s Blk_read Blk_wrtn
dev8-0 0.00 0.00 0.00 0 0

what missing is dev*-* something

Did you try this from an other login/session

Hello,

Most likely you don't have compiled the kernel with "Per partition statistics in /proc/partitions" (under Block devices), or you have an older kernel which doesn't support at all this options. Sar and iostat need this in order to show disk throughput.
