Default doctor diagnostic checks Edit

Although it’s power comes from its ability to be customized, wp doctor includes a number of default diagnostic checks considered to be recommendations for production websites.

Use wp doctor list to view these default checks:

name description
autoload-options-size Warns when autoloaded options size exceeds threshold of 900 kb.
constant-savequeries-falsy Confirms expected state of the SAVEQUERIES constant.
constant-wp-debug-falsy Confirms expected state of the WP_DEBUG constant.

The Core Development Team builds WordPress.-update Errors when new WordPress minor releaseMinor Release A set of releases or versions having the same minor version number may be collectively referred to as .x , for example version 5.2.x to refer to versions 5.2, 5.2.1, 5.2.3, and all other versions in the 5.2 (five dot two) branch of that software. Minor Releases often make improvements to existing features and functionality. is available; warns for major releaseMajor Release A set of releases or versions having the same major version number may be collectively referred to as “X.Y” -- for example version 5.2.x to refer to versions 5.2, 5.2.1, and all other versions in the 5.2. (five dot two dot) branch of that software. Major Releases often are the introduction of new major features and functionality..

pluginPlugin A plugin is a piece of software containing a group of functions that can be added to a WordPress website. They can extend functionality or add new features to your WordPress websites. WordPress plugins are written in the PHP programming language and integrate seamlessly with WordPress. These can be free in the WordPress.org Plugin Directory https://wordpress.org/plugins/ or can be cost-based plugin from a third-party-active-count Warns when there are greater than 80 plugins activated.
plugin-deactivated Warns when greater than 40% of plugins are deactivated.
plugin-update Warns when there are plugin updates available.
theme-update Warns when there are theme updates available.

To explain these further:

  • Autoloaded options are options that are automatically loaded in every request to WordPress. A size exceeding the recommended threshold could be a symptom of a larger problem.
  • Because SAVEQUERIES causes WordPress to save a backtrace for every SQL query, which is an expensive operation, using SAVEQUERIES in production is discouraged.
  • WordPress minor versions are typically security releases that should be applied immediately.

If you create a custom doctor.yml config file, you can use wp doctor list --config=<file> to view the diagnostic checks listed in the file.
