A new version of myq_gadgets has been released and you can download it here.

Changelog since the last released version here:

Version 0.0.9 -
    - Documented new reports in README
    - Updated 'thds' column in the 'cttf' report to read 'crtd' instead.
Version 0.0.8 -
    - Added a bunch more innodb reports, looking for the good stuff.
Version 0.0.7 -
    - Added an 'innodb' mode to myq_status to support 5.0+ STATUS variables.
      'myq_innodb_status' continues to handle SHOW INNODB STATUS output,
      mostly for 4.1 and earlier.
    - Beefed up the format_memory function to use recursion to determine the
      appropriate output multiplier (tera, giga, mega, kilo, etc.)

Thanks to those who tried it out and left feedback, much appreciated.

Changes:

• Changed /usr/local/bin/perl to /usr/bin/env perl to make the open source crowd happy.  Make sure the proper perl directory is first in your $PATH    
• Made the usage string contain the valid modes in myq_status
• Added check for mysql binary in MySQL_Script_Utils.pm
• Quoted the --password option in MySQL_Script_Utils.pm to handle passwords with strange characters in them.
• Setup default options string to be clearer which options are available to the scripts (like -? and -d)
• Bumped the minimum repeat time for myq_status down to 1 second.  Note that it still might take more than 1 second for the check to run.

Thanks to the few people who pointed out a copyright infringement with the name 'MySQL Gadgets' for my tool. It has now been renamed 'MyQ Gadgets'. This is actually more appropriate (but hopefully not a violation of some other copyright), since I use the 'myq' prefix on my MySQL scripts as an easy, unique prefix for command line tab completion in bash.

Today I am introducing my first open source contribution to MySQL: MyQ Gadgets. These are a small collection of tools I wrote to make it easier to see what is going on inside of a running MySQL server. There's nothing magical about them, they simply collect values from SHOW STATUS, SHOW SLAVE STATUS, and SHOW INNODB STATUS and present them in an easier-to-digest format similar to that of iostat (for those who are familiar with it). Here's an example of some data from SHOW INNODB STATUS:

./myq_innodb_status -h mysqlhost.domain.com -u user -p password -t 20
row      Inno Engine (/sec)   Buffer (/sec) (%)            Log  OS (/sec)       Semaphores
