    svmon requires root authority. If you'd bothered to read the man page or
    the command reference you'd have seen that.

    You could get round that by using sudo or something like that, but simply
    adding a group isn't going to do it.

    Any other tool giving you the same information will also require root
    access, because it must use the same source of information.

    Do you know what specific information you want and are actually going to
    use? This level of detail is seldom of any use unless you're investigating
    a particular problem. What you can get out of nmon should be sufficient for
    general monitoring.

    Thanks for providing the information.
    But I want to schedule the same in a script running through my user id on
    the AIX box.
    Svmon requires root permission to execute. Do u have any idea which group to
    be added in my group set to execute the command from my user id.
    Regards
    Akash

    AIX will always try to use 100% of real memory, (apart from a very small
    amount left unused for sudden demands).  If you've got enough memory, paging
    space use will be very low: 5% is about right, allowing for the overheads of
    LVM and a small amount of paging space use after a boot.
    There are several tools which can give you a more detailed picture of how
    memory is being used.  "svmon" is very comprehensive.  Tools such as topas
    and nmon will also give you a bit more information.

    Hi,
    Is it correct to say that AIX server is running on full 100% utilisation and
    memory usage is below 5%( paging space). What does this mean? Please explain
    if any one has any idea about it.
    Is there anyway of monitoring actual memory utilisation without paging
    space.
