                                            time and processor busy time perceived by the
                                            guest VM system. This is the logic used for the
                                            the calculation of the 'INDICATE LOAD' output.
                                            Note, however, that the resulting value depends
                                            not only on the actual activity of the guest
                                            system (the processor time used), but also on the

                                            the same physical system. The 'suspended' time
                                            (see %Susp value) will increase if there is more

                                            time in turn will result in a higher 'Logical

                                            value for the user can never exceed
                                            the maximum value. Absolute-This means

                                            minimum of the system resources.
                                            Dedicated-This means the user is
                                            running on a dedicated processor, and
                                            the share setting has no meaning.

                                            created. The VSWITCH LAN ID consists of two
                                            8-byte character fields: OWNER||NAME. The
                                            OWNER is always SYSTEM. This column is the

                                            port group in use for this VSWITCH.

                                            This address is used by clients
                                            involved in switch management.
                                            For example, a Network Management
                                            System can request Bridge MIB
                                            information from an SNMP agent
                                            using this address. If an SNMP
                                            agent has not been assigned, the
                                            IP address field will contain
                                            blanks.
    00BE  190 Character    8 VSGVMGI        The LAN management IP userid.
                                            This is the userid of the z/VM
                                            TCP/IP stack that has assigned
                                            an SNMP agent to the virtual
                                            switch in its HOME statement. If
                                            an SNMP agent has not been
                                            assigned, the userid field will
                                            contain blanks.
    00C8  200 Signed       4 VSGVLAY        The session layer, 2 or 3.

                                            (msec). This is the average
                                            time an I/O request remained
                                            pending in the I/O subsystem due
                                            to path busy conditions.
    0050   80 Dbl-Word     8 CTLDST         Average 'disconnected' time.
                                            This is the average time that the
                                            device remained disconnected from
                                            the channel while executing I/O
                                            requests. For DASD it includes the
                                            time spent for executing the SEEK
                                            and SET SECTOR orders and also any
                                            re-connect misses. High values may
                                            indicate overloaded paths, or many
                                            long SEEKs to data at opposite ends
                                            of the device. The value also includes
                                            the 'device-active-only' time where
                                            that information is available.
    0058   88 Dbl-Word     8 CTLCNT         Average 'connected' time (msec).
                                            This is the average time that the
                                            device was connected to the channel
                                            while executing I/O requests, i.e.
                                            receiving commands or actually
                                            transferring data. It includes also
                                            the search time.
    0060   96 Dbl-Word     8 CTLSRV         Average service time, i.e.
                                            the sum of function pending,
                                            disconnected and connected time.
    0068  104 Dbl-Word     8 CTLRSP         Device response time. This
                                            is the device service time plus
                                            the time during which an I/O
                                            request was waiting to be started.
                                            It is calculated based on the
                                            average I/O request queue length
                                            and the I/O rate.
