SQL BI Manager monitors several type of metrics to provide accurate information about the status and health of the Analysis Services and the instances hosting these services. The metrics are classified in the following categories:

Server Performance

This category contains the following server-related performance metrics:

• • Disk
    Includes the following charts: Disk transactions, Average Seconds per Transaction, Current Disk Queue Length, and Percent Idle Time.
  • Network
    Includes Data Transfer (bytes/sec) and Network Output Queue Length charts.
  • Cache
    Includes Cache Copy Read Hits Percent, Cache Copy Reads per Second, and Cache Faults charts.
  • CPU
    Displays CPU Thread Switching (threads waiting vs. thread switches), Percent Process Time (Percent Privileged Time vs. Percent User Time), Percent Processor Time (Processor Time vs. SSAS Processor Time), and Interrupts per Second charts.
  • Processing
    Displays a Process Working Set (Memory Working Set Vs. SSAS Working Set) chart
  • Memory
    Includes the following charts: Memory Overall Usage, Available Memory, and Page Transactions.

SSAS Performance

This category contains the following SSAS related performance metrics:

• • SSAS Processing
    Displays charts for: Rows Written, Aggregation Rows, and Index Processing.
  • Query Activity (Active Queries & All Queries)
    • Active Queries, displays a list of all currently executing MDX/DAX queries. The list can be filtered by User and Session SPID.
    • All Queries, displays charts for Cell Activity (Cells Calculated vs. Recomputes), Calculation Covers, Sonar subcubes, and Non-Empty Algorithm Utilization (Un-optimized vs. Calculated Members).
  • SSAS Memory
    Includes charts for Memory Utilization (Overall Usage, Low Limit, High Limit, Shrinkable, Non-Shrinkable), Vertipaq Memory (Vertipaq Paged vs. Vertipaq Non Paged), and Vertipaq Mapped Memory (Vertipaq Memory Mapped vs. Memory Limit Vertipaq).
  • SSAS Cache
    Displays charts for Cache Transactions (evictions/sec vs. inserts/sec) and Rate of Memory Added to Cache.
  • SSAS Formula Engine Cache
    Includes the following charts: Query Pool Threads, Query Pool Job Queue Length, Processing Pool Threads (Idle vs. Busy), Processing Pool Job Queue Length, Flat Cache Activity (Cache Lookups vs. Cache Hits), and Calculation Cache Activity (Cache Lookups vs. Cache Hits).
  • SSAS Storage Engine Cache
    Displays the following charts: Data File Activity (Bytes Read vs. Logical Reads vs. Queries From File), Cache Copy Reads, Queries Answered from Cache, Filtered Queries Answered from Cache, Average Time per Query, Dimension Cache Activity (Cache Hits vs. Cache Lookups), and Measure Group Cache Activity (Cache Hits vs. Cache Lookups).

Session

This category displays a list of user sessions within the BI environment with the following columns:
