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.outSee the top 10 most frequently run queries in the profile file dbi.prof (the default):
dbiprof –sort countSee 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".
- total
- –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.
