=head1 NAME
dbiprof - command-line client for DBI::ProfileData
=head1 SYNOPSIS
See a report of the ten queries with the longest total runtime in the
profile dump file F<prof1.out>:
dbiprof prof1.out
See the top 10 most frequently run queries in the profile file
F<dbi.prof> (the default):
dbiprof --sort count
See the same report with 15 entries:
dbiprof --sort count --number 15
=head1 DESCRIPTION
This tool is a command-line client for the DBI::ProfileData. 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.
