We are at a loss in understanding how SAR generated device IO stats relate to IOSTAT device stats. Specifically, SAR lists devices in the syntax of dev8-X while IOSTAT lists devices in the syntax of sdaX. We have not found a direct method of correlating dev8-X to sdaX. I understand that, for example, dev8-x refers to a physical disk and /dev/sda1 refers to partitions.
Some of the things that we've tried... iostat -x and iostat don't provide the correlation. Fstab does not provide the information. /proc/partitions at first glance looks like it provides the correct info but it does not. stat /dev/sda1 doesn't provide the information DF presents a realtionship between partitions and sdaX, but not dev8-X I know that we could run some tests and develop a mapping empirically, but we would rather avoid that path. Take a look at the following examples... >sar -f sa14 -d Linux 2.4.9-e.9enterprise (server2) 01/13/2003 10:00:00 PM DEV tps blks/s 10:10:00 PM dev8-0 7.14 132.02 10:10:00 PM dev8-1 7.09 7.09 10:10:00 PM dev8-2 0.03 0.03 10:10:00 PM dev8-3 0.03 0.03 10:10:00 PM dev8-4 90.04 7556.51 10:20:00 PM dev8-0 7.08 149.14 10:20:00 PM dev8-1 6.99 6.99 10:20:00 PM dev8-2 0.03 0.03 10:20:00 PM dev8-3 0.03 0.03 10:20:00 PM dev8-4 90.65 7836.31 >iostat Device: rrqm/s wrqm/s r/s w/s rsec/s wsec/s avgrq-sz avgqu-sz await svctm %util sda 1.52 6.80 0.89 6.11 12.11 99.56 15.93 0.36 51.23 7.78 0.55 sda1 0.01 0.00 0.00 0.00 0.02 0.01 13.12 0.00 181.28 96.06 0.00 sda2 0.25 0.51 0.34 0.24 3.49 4.57 13.88 0.14 232.79 19.40 0.11 sda3 0.20 0.71 0.30 0.44 3.09 8.34 15.59 0.06 77.53 16.91 0.12 sda5 0.00 0.00 0.00 0.00 0.00 0.00 8.00 0.00 100.00 100.00 0.00 sda6 0.08 3.27 0.01 1.38 0.19 36.70 26.62 0.04 28.15 8.25 0.11 sda7 0.17 0.43 0.16 0.46 2.70 7.13 15.79 0.03 44.81 15.40 0.10 sda8 0.23 1.87 0.07 3.60 1.42 42.81 12.07 0.10 27.13 9.27 0.34 sdb 252.00 343.27 52.57 36.56 2412.65 3099.16 61.84 52.43 586.65 13.92 12.41 sdb1 0.00 0.00 3.39 3.39 3.39 3.39 1.00 0.16 23.31 23.31 1.58 sdb2 252.00 343.27 49.18 33.17 2409.26 3095.77 66.85 52.27 633.03 14.47 11.91 sdc 0.00 0.00 0.20 0.00 1.42 0.00 7.10 0.03 150.44 42.87 0.09 sdc1 0.00 0.00 0.20 0.00 1.42 0.00 7.11 0.03 150.50 42.88 0.09 sdd 0.00 165.38 0.13 6.98 0.86 1378.94 194.00 0.99 138.99 28.75 2.04 sdd1 0.00 165.38 0.13 6.98 0.86 1378.94 194.01 0.99 138.99 28.75 2.04 sde 155.11 179.59 17.08 7.00 1377.38 1494.00 119.23 39.30 1632.08 32.99 7.95 sde1 155.11 179.59 17.08 7.00 1377.38 1494.00 119.23 39.30 1632.08 32.99 7.95 Thanks, ...Robert __________________________________________________ Do you Yahoo!?
