Analysis Services Trace Events

You can follow the activity of a Microsoft SQL Server Analysis Services (SSAS) instance by capturing and then analyzing the trace events generated by the instance. Trace events are grouped so that you can more easily find related trace events. Each trace event contains a set of data relevant to the event; not all pieces of data are relevant to all events.

Trace events can be started and captured using SQL Server Profiler, see Use SQL Server Profiler to Monitor Analysis Services, or can be started from an XMLA command as SQL Server Extended Events and later analyzed, see Use SQL Server Extended Events (XEvents) to Monitor Analysis Services.

The following table lists all event categories for Analysis Services with a brief description of the category. From each item in the list you can link to all events in that category and their descriptions; detailed information is available following the title link of each category.

Event Category	Description
Command Events	Collection of events for commands.
Discover Events	Collection of events for discover requests.
Discover Server State Events	Collection of events for server state discovers.
Errors and Warnings	Collection of events for server errors.
File Load and Save	Collection of events for file load and save operations reporting.
Locks	Collection of lock related events.
Notification Events	Collection of notification events.
Progress Reports	Collection of events for progress reporting.
Queries Events	Collection of events for queries.
Query Processing	Collection of key events during the process of a query execution.
Security Audit	Collection of database audit event classes.
Session Events	Collection of session events.

The following tables describe each event category and the events in that category.

Each table contains the following columns:

• Event Id
  An integer value that identifies the event type. This value is useful whenever you are reading traces converted to tables or XML files to filter the event type.

• Event Name
  The name given to the event in Analysis Services client applications.

• Event Description
  A brief description of the event
