Method and system for measuring the performance of a computer system on a per logical partition basis

摘要

Disclosed are a method and system for measuring the performance of individual logical partitions of a logically partitioned computer system. Preferably, the method and system both hardware and firmware to allow measurement samples to be collected only for user specified zones of interest. In one embodiment, the method comprises the steps of specifying a Zone or Zones of interest (a Zone being a logical partition), collecting measurement samples only from the one or more specified Zones of interest, and measuring the performance of each of these Zones using only the measurement samples collected from said each of the Zones.

1. A method for measuring performance of logical processors of a zone of interest (ZOI) of a logically partitioned computer system, said ZOI being a logical partition of the computer system, the measuring only measuring performance of the logical processors while running on physical processors executing on behalf of the ZOI, and wherein each of the physical processors enters and exits in the ZOI and executes on behalf of the ZOI over each of a plurality of separated time periods, said time periods being separated from each other by one or more time intervals, the method comprising:
capturing, by one or more physical processors, performance data of the logical processors of the ZOI, based on the logical processors running on the physical processors, the performance data comprising timer information, the timer information indicating a cumulative length of time elapsed of the logical processors while running on the physical processors and executing on behalf of the ZOI over said plurality of separated time periods; collecting the performance data from each of the physical processors when said each of the physical processors is in the ZOI; and evaluating performance of the logical processors of said ZOI using the performance data captured over said plurality of separated time periods and collected from said each of the physical processors.
