You need to select and configure a tool for the monitoring solution. What should you choose?

The MSAS11 performance object exposes counters specific to SQL Server Analysis Services 2012/2014, and the Storage Engine Query counter reports the number of storage engine queries per second. This makes it the correct tool for building a monitoring solution that tracks query activity and load on the Analysis Services instance. Performance Monitor is the appropriate lightweight, continuous monitoring tool versus Profiler, which is better suited for ad-hoc tracing.

The MSAS11:Processing counter tracks dimension and partition processing operations rather than query execution, so it does not reflect end-user query activity on the server.

SQL Server Profiler with the Query Processing: Query Subcube event captures internal subcube requests during query execution, which is useful for deep query diagnostics but is too granular and resource-intensive for an ongoing monitoring solution.

SQL Server Profiler with the Queries Events: Query Begin event captures the start of MDX queries and is useful for troubleshooting individual queries, but Profiler introduces significant overhead and is not designed for sustained production monitoring.
