this list is just here to jog my memory. perhaps someday i’ll add usage examples, but for now, just see the manual pages in sections 1 and 8.

system tools

  • vmstat

  • fstat - identify active files

  • ioststat

  • gstat

  • nfsstat

  • diskinfo (diskinfo -t)

unix tools

    # for example...
    port=33333
    ssh $host "nc -l $port" &
    bs=`echo '16 * 1024' | bc`
    time dd if=/foo bs=$bs | nc $host $port
  • top, htop, atop
