NAME

dbiprof - command-line client for DBI::ProfileData

SYNOPSIS

See a report of the ten queries with the longest total runtime in the profile dump file prof1.out:

 dbiprof prof1.out

See the top 10 most frequently run queries in the profile file dbi.prof (the default):

  dbiprof --sort count

See the same report with 15 entries:

  dbiprof --sort count --number 15

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.

OPTIONS

This program accepts the following options:

--number N

Produce this many items in the report. Defaults to 10. If set to ``all'' then all results are shown.

--sort field

Sort results by the given field. Sorting by multiple fields isn't currently supported (patches welcome). The available sort fields are:

total: Sorts by total time run time across all runs. This is the default sort.
longest: Sorts by the longest single run.
count: Sorts by total number of runs.
first: Sorts by the time taken in the first run.
shortest: Sorts by the shortest single run.
key1: Sorts by the value of the first element in the Path, which should be numeric. You can also sort by "key2" and "key3".

--reverse

Reverses the selected sort. For example, to see a report of the shortest overall time:

  dbiprof --sort total --reverse

--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 ("/") 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.

--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 "--match", If the value given starts and ends with slashes ("/") 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.

--case-sensitive

Using this option causes --match and --exclude to work case-sensitively. Defaults to off.

--delete

Sets the "DeleteFiles" option to DBI::ProfileData which causes the files to be deleted after reading. See DBI::ProfileData for more details.

--dumpnodes

Print the list of nodes in the form of a perl data structure. Use the "-sort" option if you want the list sorted.

--version

Print the dbiprof version number and exit.
