SSAS Top Commands
Identify and address SSAS performance problems
If your database performance is slow, the culprit could be SSAS. But troubleshooting SSAS is notoriously challenging. As a DBA, you can use SQL Server Profiler to capture and analyze trace events that are generated by their SSAS instance. You can also use Perfmon to track server and process performance and activity.
To get to the root of SSAS performance problems, you need the ability to go back to any point in time to see how specific events performance may have affected the following:
- Did MDX queries or XMLA commands execute?
- Do your queries need optimized?
- Do you have a performance bottleneck in the Storage Engine?
To accelerate your SSAS Multidimensional or Tabular environment performance, look no further than SSAS performance monitoring capabilities in SQL Sentry.
Analyze SSAS trace events with SQL Sentry Top Commands
The Top Command tab in the SQL Sentry Performance Analysis Dashboard provides granular insight into what's going on in your SSAS instance. SQL Sentry captures MDX, DAX, DMX, and XMLA commands running in your environment.
You can set the thresholds for collecting these commands, which by default are set to a minimum duration of one second, and you can view the runtime statistics for any command and look at:
- Queries currently running on the SSAS server
- Queries that were collected if they exceeded a minimum threshold
- Completed queries that were collected according to a date and time range
By looking at these commands and their associated resource utilization, including CPU, Formula Engine, Storage Engine, Processing, and SQL Query times, you can determine which statements are having the most impact on the performance of your monitored SSAS server.
The Top Commands tab also displays the command text associated with each query in a separate window.
What are SQL Sentry Top Commands?
The SQL Sentry Top Commands tab shows SQL Server Analysis Services (SSAS) query-level collection and any MDX, DAX, or XMLA commands that have run longer than one second. All the like queries have been rolled up and grouped together, so you can see their total impact. Top Commands helps you identify and address performance problems with SSAS.
Does SQL Sentry Top Commands support multiple modes?
The SQL Sentry Top Commands tab supports SSAS Multidimensional and Tabular modes.
Which SSAS commands can I analyze in SQL Sentry?
SQL Sentry Top Commands analyzes the performance of MDX, DAX, and XMLA commands.
How does SQL Sentry Top Commands handle events?
SQL Sentry Top Commands collect and group SQL Server Profiler trace events by event class, e.g., Command Begin/End and Query Begin/End. You can also filter events by minimum query duration time and others.
How does SQL Sentry Top Commands help me with my queries?
SQL Sentry Top Commands allow you to view both running and completed queries. You also have the ability to drill down to individual queries and analyze relevant performance counters.
