    Default HP monitoring

    I am trying to monitor a situation on an HP-UX B.11.11 9000/800
    server. It has 4gb of ram
    and 72gb of disk space. Once every 2 weeks or so it locks up. If you
    run vmstat you can
    see blocked processes:

    $vmstat 5 10

    r b w
    1 98 0
    1 98 0 .....

    and so on.

    The sar command will show:

    $sar -M 5 5

    09:46:21 cpu %usr %sys %wio %idle
    09:46:26 0 0 0 99 1
    1 0 0 98 2
    system 0 0 99 1
    09:46:31 0 0 0 97 3
    1 0 0 98 2

    It shows all idle wait I/O.

    How change I monitor this situation or determine what is happening?
    Any help will be greatly appreciated.

    thanks,

    David.

    Try the 'top' command, or even better buy "glance+" from hp, it's
    a very good tool to se current status of the system.

    You should also examine logfiles for any hints to your problems.

    wio could indicate disc problems and thos would probably be logged
    also.

    Are you using NFS mounted filesystems with automounter? I've seen this
    when the atomounter has failed to mount a filesystem and keeps trying.
