Hi,
Does anyone know the correct way to submit a request for a kernel change?
TIA Matt
Re:
<Old Post>
I'm running RedHat 6.2 (2.2.14-5.0) and am using /proc and several other utilities for performance measurement.
I'd like to be able to collect iostat-like information at the process level (instead of the system level). I once did this
through the /proc file system's prusage structure(on a Solaris box). For example, I'd like to capture input/output
blocks and characters read/written for a specific process (in this case a software application that is
running). I can use iostat as long as it's a quiescent system. However, it would be more convenient to do it at the
process level.
Does anyone know how to do this?
Two other pieces of data that were available for a process from the prusage structure were the number of system
calls (by the process) and the number of times the process was swapped out of main memory. If anyone knows
how I can obtain these from the Linux kernel (at the process level), I'd like to know!***
Thanks in advance for any help or information
*** Apparently this functionality does not exist in the 2.2.16 (and previous) kernels - which is why I'd like to submit a change request.
