SSAS Monitoring Scripts For Management Data Warehouse  at http://www.codeplex.com/SQLSrvAnalysisSrvcs

This project on Codeplex includes scripts for creating a custom collection set in Management Data Warehouse for collecting performance counter data specific to Analysis Services operations. These scripts were extracted from the A Solution for Collecting Analysis Services Performance Data for Performance Analysis project in the same codeplex release.

These scripts were updated on 3/6/2009 to fix bug related to named instances - namely, Performance Monitor counters for Analysis Services named instances must be entirely in capital letters in order to work in the Management Data Warehouse performance counter data collector.
