摘要：
A method and apparatus for obtaining a local performance measure for a particular server in a particular tier in a transaction environment in which transactions pass through multiple tiers with multiple servers at each tier. The contribution from the particular server to the total end-to-end response time for a set of transactions is scaled by the ratio of transactions passing through the particular tier to transactions passing through the particular server to obtain a scaled contribution from the particular tier. This is added to the contribution from outside the particular tier to obtain a modified total end-to-end response time from the perspective of the particular server. The modified total end-to-end response time is divided by the number of transactions in the set to obtain a modified average end-to-end response time from the perspective of the particular server, which is used to control allocation of resources to the server.
