SOS Workload Detail

The Workload Detail Screen

The Workload Detail screen displays detailed information about a specific workload. For information about workloads, refer to "Workload Groups".




Figure 31.1 SOS Workload Detail screen
To access the Workload Detail screen from any SOS display screen:
  • Type s from the SOS Enter command: prompt to view the Screen Selection Menu screen.
  • From the Screen Selection Menu screen, enter W (Workload Detail).
  • At the secondary prompt:
  • Press the Enter key to display the workload detail information for the given workload.
  • Or, select another workload from the list.
  • The Workload Detail screen will display. An example of the screen is shown in Figure 31.1.
  • Use the y command key to toggle between the normal and extended process displays.
  • Workload Detail Display Items

    WORKLOAD DETAIL

    The WORKLOAD DETAIL portion of the Workload Detail screen displays workload identification information. The data items are described in the next table.
    Table 31.1 SOS WORKLOAD DETAIL data items
    Data Item
    Description
    Workload
    The name of the workload group.
    Proc Count
    The average number of processes that exists within the workload.

    MEMORY

    The MEMORY portion of the Workload Detail screen displays process and workload memory information. The data items are described in the following table.
    Table 31.2 SOS MEMORY data items
    Data Item
    Description
    RSS
    The resident set size, which is equal to the amount of RAM the process is using, excluding shared memory.
    VSS
    The amount of virtual memory the process has reserved, which is equal to the size of the process’ core image including text, data, and stack.
    Min /s
    The number of minor page faults experienced by the process, per second (see "minor page fault").
    Maj /s
    The number of major page faults experienced by the process, per second (see "major page fault").
    Deact /s
    The number of deactivations per second (see "deactivation").

    CPU USAGE

    The CPU USAGE portion of the Workload Detail screen displays process and workload CPU information. The data items are described in Table 31.3.
    Table 31.3 SOS CPU USAGE data items
    Data Item
    Description
    CPU %
    The percentage of the current interval that the process was executing. This value is normalized for multiple processors—the sum of the CPU% values should not exceed 100.
    CPU ms
    The number of milliseconds the process was executing. The value in brackets, [ ], is a cumulative value, not an averaged cumulative value.
    User %
    The percentage of the process’ execution time spent in user mode. This includes real, nice, and negative nice time.
    Sys %
    The percentage of the process’ execution time spent in system/kernel mode. This includes memory and trap time.
    CSW %
    The percentage of the process’ execution time spent processing context switches.
    Intr %
    The percentage of the process’ execution time spent managing interrupts.

    DISK I/O USAGE

    The DISK I/O USAGE portion of the Workload Detail screen displays various process and workload disk statistics. Each data item is described in Table 31.4.
    Table 31.4
