I'm starting to realize though, to my surprise, that most of these tools haven't been updated or gained new features for a year or more. You rarely get to read recent blog postings about variable tuning either.
The most well known tools are:
- mytop - Like the *nix top but for mysql threads. Last release is from Feb 2007
- mysqlreport - '...makes a friendly report of important MySQL status values'. Last release on April 2008 and official statement of no longer being maintained.
- mysqltuner - makes tuning recommendations. Last release from April 2011 but from what I could see only bug fixes and cosmetic changes since it's first release in 2008
- mysqltuner 2.0 - a misleadingly named mysqltuner fork by Sheeri K. Cabral. Last release in April 2010. Was only active for 5 months.
So I'm quite baffled that I seem to be the only one who's currently working on a open source MySQL tuning tool, despite the fact that MySQL is getting quite popular nowadays. I really wonder why so little progress is being made in this direction. Though, I'd love to hear that this is not the case and there's is some recent tools I just haven't found.
Either way, while looking at the tools, I saw that mysqltuner 2.0 uses a comprehensive set of rules to build the recommendations. Since it has been build by a database professional, actually quite a celebrity in the db world, from what I could read, I will probably use it as the basis for my suggestions/advisory system. Gladly the GPL-License allows me to do so :)
This is very useful since it will save me a lot of work "inventing" the recommendation rules, for which you need a lot of MySQL experience.
Also I'm the only pma gsoc student that posts project related stuff which is not a weekly report! :(
[Edit 31.07.11] Ok, I just ran into all the more recent tools that I failed to find, the most extensive one being maatkit. Definitely gonna check out that one!
