Hi,

Has kernel-2.6.18-128.1.1 support for IO statistic for example when using "pidstat -d"?

Thanks in advance!

Is pidstat available in the 5.4 sysstat package or are you deviating from the stock sysstat package?

Really I don't know, still I don't test release 5.4 it would be nice that has it.

According to the man page for pidstat, 'pidstat -d' only works with 2.6.20 kernels and later. Since pidstat is not installed by the sysstat package for 5.3 (which is what 2.6.18-128.* kernel is from) it is probably a safe assumption that it won't work.

I've found kernel 2.6.18-128 on http://www.gtlib.gatech.edu/pub/centos/5.3/updates/x86_64/RPMS/

I skipped kernel-2.6.18-164.el5, so I ask again: does kernel-2.6.18-164.el5 support IO statistic, I already know what man page says :) but I wonder if that kernel has that customization....

Thanks in advance!!

It does. As Dag wrote here http://dag.wieers.com/blog/red-hat-backported-io-accounting-to-rhel5 it works nice with dstat. I tried it today.
