Practical Query Analyzer For Linux

Practical Query Analyzer produces HTML reports on the most frequent queries, slowest queries, queries by type (select/insert/update/delete), and more for both PostgreSQL and MySQL log files.

Requirements:

� Ruby � PQA itself � PostgreSQL or MySQL installation.

You can install PQA by simply unzipping it into any directory. Then open a command line window, cd into the pqa-1.4 directory, and run it like this:

[tom@hal lib]$ ./pqa.rb -file ../sample/pglog_sample.log -normalize -top 5 645 queries (65 unique), longest ran in 0.370524 seconds), parsed in 0.088793 seconds ### Queries by type SELECTs: 593 (92%) INSERTs: 51 (8%) UPDATEs: 1 (0%) ### 5 most frequent queries 61 times: SELECT total FROM forum_group_list_vw WHERE group_forum_id='' 46 times: SELECT plugin_id, plugin_name FROM plugins 46 times: INSERT INTO activity_log (day,hour,group_id,browser,ver,platform,time,page,type) VALUES (0,'','','','','','','',''); 40 times: select classname from supported_languages where language_code = '' 40 times: SELECT language_code FROM supported_languages WHERE language_id=''

� -file - required - The name of the data file to analyze � -top N - optional - "Top N queries", defaults to 10. � -format N - optional - Either "text" or "html", defaults to "text" � -normalize - optional - Removes quoted items and various bits of whitespaces � -logtype - optional - The type of log file: syslog, pglog, or mysql - defaults to pglog

What's New in This Release:

� This release fixes a silly bug that prevented it from being run directly. � It has various internal improvements. � If you install it via RubyGems, you can run it using "pqa -f file1 [file2, etc.]".
