We’ve released a new set of monitoring plugins for MySQL servers and related software. With these plugins, you can set up world-class graphing and monitoring for your MySQL servers, using your own on-premises Cacti and Nagios software. The Cacti plugins are derived from an existing set of templates we’ve been using for several years, but the Nagios check plugins are brand new. They are informed by the research we did into the causes and preventions of MySQL downtime.

Like all Percona software, the plugins are open-source and free, licensed under the GNU GPL. The source code and issue tracker are hosted at Launchpad. The 0.9.0 release is ready to download now, and the reference manual is also online. In the next release we will integrate this into our package management, so you can install through YUM and APT repositories.

The new monitoring plugins add first-rate support for MySQL to popular enterprise opensource monitoring systems, and that’s why we’ve added them to the list of software included in our support contracts. If you’re an existing customer of Percona’s MySQL Support services, your contract automatically covers these new plugins, too; you don’t need a new contract for that. Under the support contract, you’ll get help installing, configuring, troubleshooting, and administering your monitoring plugins, as well as being entitled to bug fixes. And as always, we’re also available to extend the plugins to support your environment or broaden the range of systems and software that they can monitor.

Please use the Launchpad bug tracker to report issues. Happy monitoring!
