fiostats is a software that offers file I/O statistics by process for Linux.Developer commentsThis project was started to address a need for a product I worked on wherein a critical, time sensitive process was blocking for long periods of times due to file I/O. The 2.4 kernel (and early 2.6 kernels as I have since learned) do nottrack file I/O by process, so there is no direct means of knowing which processwas putting the load on the I/O subsystem at any point in time. I/O requests can affect system performance, and as a result one process canimpact another. For example a process that dumps a gigabyte to disk in a shortinterval can keep syslogd from tending to its queue which in turn can causeprocesses to block while waiting to send a message via syslog. Alternatively,a process pushing gigabytes off a server causes a burst of reads which ca
