ClearTrace
New: ClearTrace for Extended Events imports extended event files from SQL Server 2019, SQL Server 2017, SQL Server 2016, SQL Server 2014, SQL Server 2012, SQL Server 2008, and SQL Server 2008.
ClearTrace for Trace imports SQL Server 2016, SQL Server 2016, SQL Server 2014, SQL Server 2012, SQL Server 2008, SQL Server 2005, SQL Server 2000 trace and Profiler files into SQL Server and displays summary performance information. (The latest version of SMO no longer supports reading Trace files. That means I’m unable to support reading Trace files from SQL Server 2019.)
Features
- Summarize SQL Server Query Performance
- Enhance SQL Server Performance Tuning
Normalized SQL Statements
ClearTrace “normalizes” the SQL statements to eliminate transient differences in SQL statements. For example, the following statement
Select * From qryLinksByNewsletterID Where NewsletterID=19
is normalized to
SELECT * FROM QRYLINKSBYNEWSLETTERID WHERE NEWSLETTERID={##}
This allows the common SQL statements to be grouped together to determine their impact on the system. Other steps include:
- All numeric, string and date constants are converted to a placeholder
- Prepared SQL is displayed as the actual statement executed
- Server-side cursors are prefixed with “{CURSOR}” so they can be identified and removed
- sp_executesql displays the actual SQL statement executed
- Stored Procedure names are pulled from the RPC:Completed event
Integrated Query Results
- Includes a simple query tool to display the performance data
- Groups by Normalized SQL text, Application, Host or Login
- Filters by Application, Host or Login
- Sorts by CPU, Reads, Writes or Duration
Other Features
- Will process all trace files sequentially from a trace
- Stores the data in SQL Server where it can be easily queried or stored in a data warehouse
- Can move the trace files to an archive directory after processing is complete.
