innotop 1.3.5 is the latest release of the increasingly popular MySQL and InnoDB monitor. I recommend everyone upgrade to this release. Aside from incomplete documentation, it's close to a stable 1.4 release (I'm counting on you to find the bugs!). There are many significant new features since version 1.3, which make it more powerful and easier to use.

I just made a snapshot of the development branch of the innotop MySQL and InnoDB monitor, and released it as version 1.3.0. This code will eventually become version 1.4. Here's what's new.

A couple of weeks ago I submitted a request to open a new project on Sourceforge for the innotop MySQL and InnoDB monitor. I want to make it easier for others to collaborate, especially package maintainers. Yesterday I got word of its approval. I have done a quick-and-dirty import of the source code into its new home, and I'm now continuing work on the next major version, which I've been working on for about six weeks. This post is about Sourceforge, what I've gotten done, and also to ask for your help.

Daniel Nichter has released version 3.0 of mysqlreport, one of my favorite tools for quickly comprehending the overall state of a MySQL server. The new version prints out the most important information about InnoDB.

I wrote a while ago about a program I wrote to export GnuCash data into a MySQL database, including a couple of queries against the resulting schema. I've made some improvements since then to allow a simple overlay of my wife's expense categories onto the GnuCash hierarchy. This article explains the improved schema, and includes some more useful tools and queries.

A kind soul has contributed a Debian/Ubuntu package for the innotop MySQL and InnoDB monitor. Thanks Sebastien Estienne!

A great post by Pete Lacey about SOAP and the problems one WILL encounter when trying to use it and understand it. Please someone make it go away!

I recently got a message letting me know FreeBSD users will soon be able to install the innotop MySQL and InnoDB monitor through ports. Gentoo GNU/Linux users can find innotop in Portage.

This is the fourth in a series of articles on profiling MySQL. My past three articles have explained how to measure the work a query causes MySQL to do. In this article I introduce a tool I've written to do the work for you and produce a compact, readable report of that work, with all the math already done, and the measurements labelled and grouped for ease of comprehension. With this tool you can understand query performance at a glance.

I've made more improvements to the duplicate index checker. I addressed a MySQL bug Roland Bouman mentioned to me, added more tests to the suite, and made changes so it considers more types of indexes now (HASH, BTREE, SPATIAL). I made no changes to the foreign key checking.
