MySQLTuner reaches 5,000 downloads!

Posted by: major in Database, Development, Fun

I’ve just reviewed the stats for MySQLTuner, and it crossed the 5,000 download mark last week! Thanks to all of you who have helped me make it a successful tool for MySQL server optimization.

With that said - how can MySQLTuner be improved to help you? Please let me know, and I’ll get started on those features!

   Hi,

   Thanks for a great tool. This has saved me a lot of time when doing initial mysqld setups.

   However, I found an issue when running against mysql cluster (on the “server” node of course) where some variables don’t quite work out:

   Argument “NULL” isn’t numeric in addition (+) at ./mysqltuner.pl line 256 (#1)
   (W numeric) The indicated string was fed as an argument to an operator
   that expected a numeric value instead. If you’re fortunate the message
   will identify which operator was so unfortunate.

   Use of uninitialized value in concatenation (.) or string at ./mysqltuner.pl
   line 609 (#2)
   (W uninitialized) An undefined value was used as if it were already
   defined. It was interpreted as a “” or a 0, but maybe it was a mistake.
   To suppress this warning assign a defined value to your variables.

   To help you figure out what was undefined, perl tells you what operation
   you used the undefined value in. Note, however, that perl optimizes your
   program and the operation displayed in the warning may not necessarily
   appear literally in your program. For example, “that $foo” is
   usually optimized into “that ” . $foo, and the warning will refer to
   the concatenation (.) operator, even though there is no . in your
   program.

   I will check this post periodically should you need more information.

   Hey snajjar. Thanks for the bug report! I’ll get in touch with you via e-mail and hopefully we can sort this out!
