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 …

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 …
