It allows you to analyze the profile data file produced by DBI::ProfileDumper and produce various useful reports. =head1 OPTIONS This program accepts the following options: =over 4 =item --number N Produce this many items in the report. Defaults to 10. If set to "all" then all results are shown. =item --sort field Sort results by the given field. Sorting by multiple fields isn't currently supported (patches welcome). The available sort fields are: =over 4 =item total Sorts by total time run time across all runs. This is the default sort. =item longest Sorts by the longest single run. =item count Sorts by total number of runs. =item first Sorts by the time taken in the first run. =item shortest Sorts by the shortest single run. =item key1 Sorts by the value of the first element in the Path, which should be numeric. You can also sort by C<key2> and C<key3>. =back =item --reverse Reverses the selected sort. For example, to see a report of the shortest overall time: dbiprof --sort total --reverse =item --match keyN=value Consider only items where the specified key matches the given value. Keys are numbered from 1. For example, let's say you used a DBI::Profile Path of: [ DBIprofile_Statement, DBIprofile_Methodname ] And called dbiprof as in: dbiprof --match key2=execute Your report would only show execute queries, leaving out prepares, fetches, etc. If the value given starts and ends with slashes (C</>) then it will be treated as a regular expression. For example, to only include SELECT queries where key1 is the statement: dbiprof --match key1=/^SELECT/ By default the match expression is matched case-insensitively, but this can be changed with the --case-sensitive option. =item --exclude keyN=value Remove items for where the specified key matches the given value. For example, to exclude all prepare entries where key2 is the method name: dbiprof --exclude key2=prepare Like C<--match>, If the value given starts and ends with slashes (C</>) then it will be treated as a regular expression. For example, to exclude UPDATE queries where key1 is the statement: dbiprof --match key1=/^UPDATE/ By default the exclude expression is matched case-insensitively, but this can be changed with the --case-sensitive option. =item --case-sensitive Using this option causes --match and --exclude to work case-sensitively. Defaults to off. =item --delete Sets the C<DeleteFiles> option to L<DBI::ProfileData> which causes the files to be deleted after reading. See L<DBI::ProfileData> for more details. =item --dumpnodes Print the list of nodes in the form of a perl data structure. Use the C<-sort> option if you want the list sorted. =item --version Print the dbiprof version number and exit. =back =head1 AUTHOR Sam Tregar <sam@tregar.com> =head1 COPYRIGHT AND LICENSE Copyright (C) 2002 Sam Tregar This program is free software; you can redistribute it and/or modify it under the same terms as Perl 5 itself. =head1 SEE ALSO L<DBI::ProfileDumper|DBI::ProfileDumper>, L<DBI::Profile|DBI::Profile>, L<DBI|DBI>. =cut
