hi all, Occasionally I'd like to know which application(s) is/are using the most disk bandwidth. The reason is, on my desktop and my laptop, I often have background jobs which do a lot of IO and I'd like to know which program it is exactly so I can take appropriate action if IO is slowing down interactivity too much.
Generally, I already have a reasonably good system (svn, git, updatedb, doxygen, rdiff-backup and other IO intensive programs normally run under ionice -c 2 -n 7 since interactivity is more important than pure time-to-finish). but sometimes I still see IO storms and my desktop (less often my laptop, since I do more on my desktop and it's a slower computer) will stall for 5-10 seconds and then continue. top will almost always show me what the IO hogging apps are because normally there's a good correlation between IO use and CPU use, but that's not always the case. apart from sar, iostate, vmstat, (none of which, AFAICT, will show me what application is hogging the disk) what command line monitoring program is there that will show disk hogging by program name (not just aggregate numbers per device). tiger _________________________________________________ Philippine Linux Users' Group (PLUG) Mailing List [email protected] (#PLUG @ irc.free.net.ph) Read the Guidelines: http://linux.org.ph/lists Searchable Archives: http://archives.free.net.ph
