linux performance - identifying highly resource consumptive programs
Hello Experts,
I am trying to analyze the performance of a linux system, focusing on I/O. I see some mechanisms to determine which processes are using the most I/O, however is there a way to track what program a given process is running at a point in time? Thanks

strace will give you lots of information on the system calls a particular process is using.

Install iotop. It works like top, but for I/O.
If that is not what you are looking for, please explain what you mean by: "however is there a way to track what program a given process is running at a point in time"

iotop *does* look like it will give me what I'm looking for. I think you understand what I'm looking for.
However, I don't get to install anything on the system being evaluated until it's been tested/retested/verified/p
For the moment, I will pursue the non-trival task of getting iotop running on the machine. In the meantime any other suggestions welcome.
