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. AUTHOR

NAME
DBI::ProfileData - manipulate DBI::ProfileDumper data dumps SYNOPSIS
The easiest way to use this module is through the dbiprof frontend (see dbiprof for details): dbiprof --number 15 --sort count This module can also be used to roll your own profile analysis: # load data from dbi.prof $prof = DBI::ProfileData->new(File => "dbi.prof"); # get a count of the records in the data set $count = $prof->count(); # sort by longest overall time $prof->sort(field => "longest"); # sort by longest overall time, least to greatest $prof->sort(field => "longest", reverse => 1); # exclude records with key2 eq 'disconnect' $prof->exclude(key2 => 'disconnect'); # exclude records with key1 matching /^UPDATE/i $prof->exclude(key1 => qr/^UPDATE/i); # remove all records except those where key1 matches /^SELECT/i $prof->match(key1 => qr/^SELECT/i); # produce a formatted report with the given number of items $report = $prof->report(number => 10); # clone the profile data set $clone = $prof->clone(); # get access to hash of header values $header = $prof->header(); # get access to sorted array of nodes $nodes = $prof->nodes(); # format a single node in the same style as report() $text = $prof->format($nodes->[0]); # get access to Data hash in DBI::Profile format $Data = $prof->Data(); DESCRIPTION
This module offers the ability to read, manipulate and format DBI::ProfileDumper profile data. Conceptually, a profile consists of a series of records, or nodes, each of each has a set of statistics and set of keys. Each record must have a unique set of keys, but there is no requirement that every record have the same number of keys. METHODS
The following methods are supported by DBI::ProfileData objects. $prof = DBI::ProfileData->new(File => "dbi.prof") $prof = DBI::ProfileData->new(Files => [ "dbi.prof.1", "dbi.prof.2" ]) Creates a a new DBI::ProfileData object. Takes either a single file through the File option or a list of Files in an array ref. If multiple files are specified then the header data from the first file is used. $copy = $prof->clone(); Clone a profile data set creating a new object. $header = $prof->header(); Returns a reference to a hash of header values. These are the key value pairs included in the header section of the DBI::ProfileDumper data format. For example: $header = { Path => '[ DBIprofile_Statement, DBIprofile_MethodName ]', Program => 't/42profile_data.t', }; Note that modifying this hash will modify the header data stored inside the profile object. $nodes = $prof->nodes() Returns a reference the sorted nodes array. Each element in the array is a single record in the data set. The first seven elements are the same as the elements provided by DBI::Profile. After that each key is in a separate element. For example: $nodes = [ [ 2, # 0, count 0.0312958955764771, # 1, total duration 0.000490069389343262, # 2, first duration 0.000176072120666504, # 3, shortest duration 0.00140702724456787, # 4, longest duration 1023115819.83019, # 5, time of first event 1023115819.86576, # 6, time of last event 'SELECT foo FROM bar' # 7, key1 'execute' # 8, key2 # 6+N, keyN ], # ... ]; Note that modifying this array will modify the node data stored inside the profile object. $count = $prof->count() Returns the number of items in the profile data set. $prof->sort(field => "field") $prof->sort(field => "field", reverse => 1) Sorts data by the given field. Available fields are: longest total count shortest The default sort is greatest to smallest, which is the opposite of the normal Perl meaning. This, however, matches the expected behav- ior of the dbiprof frontend. $count = $prof->exclude(key2 => "disconnect") $count = $prof->exclude(key2 => "disconnect", case_sensitive => 1) $count = $prof->exclude(key1 => qr/^SELECT/i) Removes records from the data set that match the given string or regular expression. This method modifies the data in a permanent fashion - use clone() first to maintain the original data after exclude(). Returns the number of nodes left in the profile data set. $count = $prof->match(key2 => "disconnect") $count = $prof->match(key2 => "disconnect", case_sensitive => 1) $count = $prof->match(key1 => qr/^SELECT/i) Removes records from the data set that do not match the given string or regular expression. This method modifies the data in a perma- nent fashion - use clone() first to maintain the original data after match(). Returns the number of nodes left in the profile data set. $Data = $prof->Data() Returns the same Data hash structure as seen in DBI::Profile. This structure is not sorted. The nodes() structure probably makes more sense for most analysis. $text = $prof->format($nodes->[0]) Formats a single node into a human-readable block of text. $text = $prof->report(number => 10) Produces a report with the given number of items.
