Using a double dash removes the daily collection feature. This command is only valid for
begin and end times specified on the same day, month, and year.
-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 Open Database Connectivity (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.
-f { Bin | Bincirc | CSV | TSV | SQL } Defines the log format for the output. You can
choose between binary, circular binary, CSV, Tab Separated Value (TSV), and Structured Query
Language (SQL).
-[-]a Appends data to the existing log file when used with a single dash. Overwrites the existing
log file when used with a double dash. The default setting is to overwrite the existing log file.
-[-]v [ nnnnnn | mmddhhmm ] Attaches versioning information (either a number or the
current date) to the end of the log filename when used with a single dash.
