Thread: Realtime Application / Disk IO / Network IO monitoring

  1. #1

    Thumbs up Realtime Application / Disk IO / Network IO monitoring

    Hello All
    What have i found out so far...
    TOP ------------------------- shows ALL runnings tasks
    PS -------------------------------- this shows a static task "onetime, snapshot" overview
    NETSTAT (-l of -p)--------------- i can see which task uses which ports (tcp,udp)
    KDE's SYSTEM MONITOR ------ shows tasks in a tree structure.

    Questions
    1. Is is possible to use TOP for only 1 application? (e.g. via command-line switch).
    I haven't found this option in the man / info pages (yet).

    2. Is their a way to make the Disk IO traffic visible "under an application / task"?

    3. Is it possible to use NETSTAT for only one applications?

    Thanks for you time and answers,
    Ronald

    1) no

    2) need more info on this question??

    3) Use grep to filter the output
    example: netstat -l | grep somestring

    | is the pipe and you are piping the output of netstat to grep.
    somestring is a set of characters in the line/lines that you have interest in.

    I am a complete command line junkie, but in this exceptional case I would say: Try the very fine 'Systemmonitor' program available from the Systems Menu.

    Hi
    Install the sysstat package, this includes iostat, mpstat and pidstat,
    then of course sar. I would say pidstat is the tool your looking for.
    There is also vmstat on a default install.
