System Dashboard

This plugin provides a central dashboard to monitor various WordPress components, processes and data, including server hardware, software and resource usage. Pairs well with Query Monitor to help you do some solid dev work.

“A must-have for serious WordPress developers.” ~Jeff Starr

“A power tool for WordPress site builders and plugin/theme developers that will save a ton of time.” ~Ivan Arnaudov

“Hands down one of the best plugins for developers. Keep up the good work!” ~Abracadabra DGTL

Despite having 20 WordPress modules and 4 server modules, the single-page dashboard loads fast as queries are optimized and most modules employ fast AJAX loading of data. It does not weight down wp-admin, and nothing is loaded on the front-end. Install, activate and let it sit there ready to summon the info/data you need.

To preview the module screenshots more easily, please scroll down the github repo. Here’s a rundown of the available modules…

Technical Notes

• Requires shell_exec and exec functions enabled for some modules to work properly. e.g. the Hooks > Active Plugins tool.
• There’s an MU (must-use) plugin that unloads all other plugins for admin-ajax calls initiated from the dashboard, so these calls stay fast no matter how complex and big your site is.
• The longest first load is probably the Hooks > Active Plugins tool, which scans action and filter hooks from all active plugins on the site. The more plugins are active, the longer it takes. If your server/hosting has a low execution time limit, you may need to load the module two or three times for the scan to complete. Once complete, subsequent loads of the module should be much much faster.
• This plugin has been tested to work with servers powered by NGINX, Apache and Litespeed, and also sites using PHP 7+ and 8+.
