SUMMARY

This article describes views that you can use to analyze the performance data in the trace file that is created in the following article in the Microsoft Knowledge Base:

283696

(http://support.microsoft.com/kb/283696/EN-US/ )

INF: Job to Monitor SQL Server 2000 Performance and Activity

Before you create these views, you must import the trace file into a SQL Server 2000 table named ActivityTrace. The script for a stored procedure, trace_gettable, imports the data from the trace file to a SQL Server 2000 table.

INF: How to View SQL Server 2000 Activity Data

Use the following views to analyze performance data:

The v_sysperfinfo view lists the performance counters recorded by the trace from the sysperfinfo table.
The v_BufferCacheHitRatio view calculates the buffer cache hit ratio.
The v_difference view lists the difference between maximum and minimum counter values.
The v_Access_methods view lists all counters for the access methods object. Change %:Access Methods% in the v_Access_methods view to another object to list other counters.
The v_object_names view lists all the performance object names.
