    Sorry,
    my calculation was not correct

    I think it is for
    en1: 99 kByte/s
    and for
    en3: 56 kByte/s

    But is this a normal value and what is the way to trace exactly (and
    observe the peaks)? Only with topas?

    Best regards,
    Frank Mueller

    Hi,

    on one of our SP node (AIX 5.2) runs a DB2 database (V8). All 120 clients
    (Windows) works with this database and they are connect over 100MBit
    Ethernet cards in our network.

    Now we want the same application build again. But now the server is in
    another location/city than the clients and we must work over a WAN and not
    a LAN.

    But I do not know the capacity which we need for the WAN or how big must
    the line from city to city.

    I reset the adapter statistik and check the output after 7h with entstat.
    Here the result for en1 and en2:

    -------------------------------------------------------------
    ETHERNET STATISTICS (en1) :
    Device Type: Gigabit Ethernet-SX PCI Adapter (14100401)
    Hardware Address: 00:02:55:9a:54:e9
    Elapsed Time: 0 days 7 hours 18 minutes 18 seconds

    Transmit Statistics: Receive Statistics:

    Bytes: 2633851309 Bytes: 24161670
    Interrupts: 5307 Interrupts: 358738
    Transmit Errors: 0 Receive Errors: 0
    Packets Dropped: 0 Packets Dropped: 0
                                                  Bad Packets: 0
    Max Packets on S/W Transmit Queue: 77
    S/W Transmit Queue Overflow: 0
    Current S/W+H/W Transmit Queue Length: 0

    -------------------------------------------------------------
    ETHERNET STATISTICS (en3) :
    Device Type: Gigabit Ethernet-SX PCI Adapter (14100401)
    Hardware Address: 00:02:55:9a:54:e5
    Elapsed Time: 0 days 2 hours 53 minutes 8 seconds

    Transmit Statistics: Receive Statistics:
    -------------------- -------------------
    Packets: 1535981 Packets: 1067630
    Bytes: 1853344547 Bytes: 199525044
    Interrupts: 29289 Interrupts: 1042437
    Transmit Errors: 0 Receive Errors: 0
    Packets Dropped: 0 Packets Dropped: 0
                                                  Bad Packets: 0
    Max Packets on S/W Transmit Queue: 105
    S/W Transmit Queue Overflow: 0
    Current S/W+H/W Transmit Queue Length: 3

    When I calculte the bytes (for example Transmit) I get for en1 99 MByte/s
    and for en3 56 MByte/s
    I think that is very high and I want now control this values with a other
    tool?
    And this is the average and not a peak.

    Is this possible?

    Best regards,
    Frank Mueller
