Overview

wp doctor lets you easily run a series of configurable checks to diagnose what's ailing with WordPress.

Without wp doctor, your team has to rely on their memory to manually debug problems. With wp doctor, your team saves hours identifying the health of your WordPress installs by codifying diagnosis procedures as a series of checks to run with WP-CLI. wp doctor comes with dozens of checks out of the box, and supports customized doctor.yml files to define the checks that are most important to you.

Each check includes a name, status (either "success", "warning", or "error"), and a human-readable message. For example, cron-count is a check to ensure WP Cron hasn't exploded with jobs:

$ wp doctor check cron-count
+------------+---------+--------------------------------------------------------------------+
| name       | status  | message                                                            |
+------------+---------+--------------------------------------------------------------------+
| cron-count | success | Total number of cron jobs is within normal operating expectations. |
+------------+---------+--------------------------------------------------------------------+

Want to pipe the results into another system? Use --format=json or --format=csv to render checks in a machine-readable format.

wp doctor is designed for extensibility. Create a custom doctor.yml file to define additional checks you deem necessary for your system:

plugin-w3-total-cache:
  check: Plugin_Status
  options:
    name: w3-total-cache
    status: uninstalled

Then, run the custom doctor.yml file using the --config=<file> parameter:

$ wp doctor check --fields=name,status --all --config=doctor.yml
+-----------------------+--------+
| name                  | status |
+-----------------------+--------+
| plugin-w3-total-cache | error  |
+-----------------------+--------+

Running all checks together, wp doctor is the fastest way to get a high-level overview to the health of your WordPress installs.
