## Description

Site Pulse is a monitoring plugin that runs entirely inside WordPress. It checks
your pages and database automatically after each page load (via the shutdown hook)
and shows the results on a dashboard in wp-admin. When something goes wrong, it 
sends you an email.

No external monitoring service or API key required.

**What it monitors:**

 * Page HTTP status and response time (including login-required pages)
 * DB read/write performance via test queries (SELECT, INSERT, UPDATE, DELETE)
 * Slow queries (requires `SAVEQUERIES` to be enabled)
 * DB health indicators: autoload option size, expired transients, post revision
   bloat

**Alerts:**

The plugin sends email alerts when a page returns an error, responds too slowly,
or a DB test query fails. You can choose which alert types to enable, and duplicate
alerts are suppressed for 1 hour.

**Dashboard:**

The admin dashboard shows an overall site health indicator, then breaks down into
page monitoring and DB status. Each section has charts (powered by Chart.js), error
logs, and detail views.

#### Third-Party Libraries

This plugin bundles Chart.js (MIT license) for rendering charts on the admin dashboard.
All files are included locally — no external requests are made.

 * [Chart.js](https://www.chartjs.org/) — MIT License
 * [chartjs-adapter-date-fns](https://github.com/chartjs/chartjs-adapter-date-fns)—
   MIT License

## Installation

 1. Upload the `site-pulse` folder to `/wp-content/plugins/`.
 2. Activate the plugin.
 3. Open “Site Pulse” in the admin menu.
 4. Go to “Site Pulse > Settings” to add URLs and configure alerts.

Checks run automatically after page loads using a shutdown hook, so no server-side
cron setup is required. The plugin throttles itself to run at most once every 15
minutes.

## FAQ

### Does this need an external service?

No. Everything runs inside WordPress.

### Will it slow down my site?

Checks run after the response is sent to the visitor (shutdown hook), so page speed
is not affected. Slow query detection uses `SAVEQUERIES` which does add overhead—
only enable it when you need it.

### Can it monitor pages that require login?

Yes. In Settings, tick the “Auth” checkbox next to any URL that requires login and
pick a user account. The plugin creates temporary auth cookies (valid for 60 seconds)
for those URLs.

### What happens on uninstall?

All tables and options created by the plugin are deleted.

### How long is data kept?

Check results are kept for 7 days. Slow query logs and alert history are capped 
at 100 entries each.
