WORKING WITH PERFORMANCE INFORMATION 461
-f { Bin | Bincirc | CSV | TSV | SQL } Defines the log format for the output. You can
choose between binary, circular binary, CSV, TSV, and SQL.
-t value Changes the sampling rate by writing every nth record into the output file. For
example, if the original file contains one record for each second, specifying a value of two would
change the sampling rate to one every other second. The default setting writes every record into
the output.
-o { Filename | DSN!Log } Specifies the output information for the collection. You can use
an output file by specifying a path and filename. As an alternative, you can specify a SQL database
(for any vendor that supports SQL) by including the ODBC DSN and the log set name
within the SQL database. (See the ???Working with ODBC Data Sources??? section of Chapter 14 for
information on configuring ODBC from the command line.) The default setting is to use a file
with the same name as the performance collection and a BLG extension for counters or an ETL
extension for traces.
-b M/d/yyyy h:mm:ss[{ AM | PM }] Defines the starting time for the collection.
