If you have recently attended some Percona Live events or if you have checked some slides from Yves Trudeau, you may have heard about Percona Replication Manager (PRM), a new high availability tool for MySQL.
PRM is an OCF Resource Agent for Corosync / …
[Read more]I’m proud to announce the GA release of version 2.1 of Percona Toolkit. Percona Toolkit is the essential suite of administrative tools for MySQL.
With this release we introduce a new version of pt-online-schema-change, a tool that enables you to ALTER large tables with no blocking or downtime. As you know, MySQL locks tables for most ALTER operations, but pt-online-schema-change performs the ALTER without any locking. Client applications can continue reading and writing the table with no interruption.
With this new version of the tool, one of the most painful things anyone experiences with MySQL is significantly alleviated. If you’ve ever delayed a project’s schedule because the release involved an ALTER, which …

[Read more]Most of the Nagios plugins included with the Percona Monitoring Plugins are purpose-built for specific scenarios that I found in my research to be frequent, severe, or subtle causes of problems in MySQL systems. They are intentionally not generic because I wanted to focus on doing one thing with each plugin, and doing it excellently. This makes the plugins easier to set up and use, and I believe it should help avoid some of the common problems such as spammy alerts.
There is one “generic, flexible” plugin, however, which you can use for fairly arbitrary checks of status counters and variables. This is the …

[Read more]I am writing a specification for updating pt-online-schema-change. The outline of the changes I want to make is here: http://www.percona.com/docs/wiki/ptdev:blueprints:redesign-pt-online-schema-change
The idea is to make the tool Do The Right Thing, with features such as automatically throttling its operation to avoid causing replicas to lag. Many of the features and improvements are similar to those added to the newly rewritten pt-table-checksum.
If you have any comments on it, please write to the mailing list with your suggestions. Thanks!
Percona Toolkit version 2.0.4 is available for immediate download. This release fixes 25 bugs and is a bug-fix release only, with the exception of a minor new filtering option for pt-kill. The change log is available on Launchpad. There are links to the documentation, downloads, bug reporting system, and mailing list on the toolkit homepage.
Percona Toolkit is open-source and free, but we recommend a support contract, which entitles you to bug fixes and assistance using the tools, among other benefits.
With this release we are introducing a new release model, which matches most people’s expectations of a software lifecycle. We will place all new features into the upcoming series (currently the 2.1 …
