Hi, folks. I want to diagnose which programs trigger disk writes, so I'm wondering if there's a way to determine which processes write to which files on what disks with what speed? I know there are gstat(8) and iostat(8) which show how busy each disk is, but they do not show which files are being written and which processes are doing it.
