RMSU

Type

OMEGAMON Minor command

Description

Displays 4-Hour Rolling Average MSUs (Millions of Service Units per hour) information. Unmodified, RMSU displays summary statistics. Prefixed with an X, RMSU displays detailed statistics. Suffixed by DB, RMSU displays hexadecimal and character dump of the RMSU data collection work area.

The values displayed by this command depend on platform support for the services that retrieve the data and whether License Manager is being used to define LPAR Capacity limits. RMSU displays the following information:
  • The 4-Hour Rolling Average MSU.
  • If the LPAR has a defined capacity set:
    • The percentage of time during the 4-Hour Rolling Average MSU period when the LPAR was capped by WLM.
    • The percentage of that time the LPAR was uncapped.
  • The LPAR capacity in MSUs per Hour.
  • The percentage of LPAR Capacity (or Defined LPAR Capacity) that the 4-Hour Rolling Average MSU value represents.
  • If the LPAR is defined as a member of an LPAR Capacity Group:
    • The LPAR Group Name.
    • The LPAR Group Capacity in MSUs per Hour.
    • The percentage of the LPAR Group Capacity that the LPAR 4-Hour Rolling Average MSU value represents.
    • Whether or not the capacity limit is based on the LPAR’s entitlement calculated as the number of standard CPs configured to the LPAR (including reserved CPs) multiplied by the MSUs/CP. If so a parenthesized “(Entitled)” is displayed. Alternatively, if a Defined Capacity is specified for the LPAR, a parenthesized literal “(Defined)” is displayed.
    • The average unused LPAR Group service units available over the last 4 hours, in millions of service units (MSUs).

      This value is calculated using the service consumption of all members of the LPAR Group the current LPAR is a member of. If this value is negative, the LPAR Group members are currently subject to LPAR Group capping. The value is displayed in green if it represents more than 10% of the LPAR Group Capacity Limit, yellow if between 0.01 and 10%, and red at 0% or negative.

    • The current LPAR Capacity Limit enforced by the LPAR Group, in millions of service units per hour (MSUs).
      This limit is affected by several factors:
      • The value is only displayed if the LPAR is in an LPAR Group.
      • If an LPAR Defined Capacity Limit is specified this value will never exceed that limit. If LPAR Group Capping is in effect, the value is calculated every 10 seconds and ranges from the LPAR Group entitlement minimum to a maximum of the LPAR Defined Capacity Limit.
      • If no LPAR Defined Capacity is specified:
        • If the LPAR Group is not currently being capped, the value will be equal to the LPAR Group Capacity.
        • If LPAR Group Capping is in effect, the value is calculated every 10 seconds and ranges from the LPAR Group entitlement minimum to a maximum of the LPAR Group Capacity Limit.
        • If Group Capping is in effect, this value is displayed in red.

+ LPAR Capacity Limit (Entitled)        670 (  8.8% LPAR Capacity utilized)     
When prefixed by an X, RMSU additionally displays the following information for each time period comprising the 4-Hour Rolling Average timeframe in chronologically descending sequence:
  • The percentage of the time period the LPAR was uncapped.
  • The MSUs per hour consumed by the LPAR during the time period while uncapped.
  • The percentage of the LPAR capacity MSUs per hour consumed by the LPAR while uncapped.
  • The percentage of the time period the LPAR was capped by WLM soft-capping.
  • The MSUs per hour consumed by the LPAR during the time period while capped by WLM soft-capping.
  • The percentage of the LPAR capacity consumed by the LPAR while capped by WLM soft-capping
  • Unused LPAR Group service units, in millions of service units per hour, over the time period the display row represents.

    If the value is negative, the LPAR Group members were subject to LPAR Group capping during the time period. The value is displayed in green if the value is greater than 10% of the LPAR Group Capacity Limit; in yellow if between 0.01 and 10%; and red at 0% or negative (LPAR Group Capping is in effect).
