WordPress Uptime Monitoring

WordPress powers 43% of the web—but plugins, themes, and hosting issues can take your site down without warning. Monitor your WordPress site and catch problems before visitors (or Google) notice.

WordPress sites face unique challenges: plugin conflicts, PHP memory limits, database connection errors, and targeted attacks. A site that works fine one minute can show the "white screen of death" the next.

Common WordPress downtime causes

Plugin conflicts

A plugin update can break your site instantly. When two plugins conflict or a plugin has a PHP error, WordPress can crash completely. Monitoring catches these issues right after updates.

PHP memory exhaustion

The infamous "Allowed memory size exhausted" error. Heavy plugins, poorly optimized themes, or traffic spikes can push your site over its memory limit.

Database connection errors

"Error establishing a database connection" is one of the most common WordPress errors. It can mean your database server is down, credentials changed, or the database is corrupted.

Hosting issues

Shared hosting can become overloaded. Server maintenance, disk space issues, or exceeded bandwidth limits can all take your site offline.

Security attacks

WordPress is a common target for brute force attacks, malware injections, and DDoS. These can crash your site or cause your host to suspend it.

What to monitor on your WordPress site

Essential WordPress monitors

  • Homepage – Basic availability check with keyword verification
  • Critical pages – Contact forms, checkout pages, landing pages
  • SSL certificate – Get alerts before your HTTPS expires
  • Response time – Catch slow performance before it hurts SEO

Advanced WordPress monitors

  • wp-admin/wp-login.php – Ensure backend is accessible
  • WP REST API – Monitor /wp-json/wp/v2/ endpoints
  • Cron jobs – Use heartbeat monitoring for WP-Cron or real cron
  • WooCommerce checkout – If you run an online store

WordPress monitoring best practices

Use keyword monitoring

Don't just check if your site returns HTTP 200. Verify specific content exists on the page. This catches partial failures where WordPress returns a blank page or error message but still responds with "200 OK".

Monitor after updates

Plugin and theme updates are the most common cause of WordPress crashes. Make sure monitoring is active when you update, and consider manual checks immediately after major updates.

Set up escalation

For business-critical WordPress sites, set up escalation to SMS or phone calls. A blog post can wait, but an e-commerce checkout can't.

Track response time trends

WordPress sites tend to slow down over time as you add plugins and content. Response time monitoring helps you catch performance degradation before it impacts SEO or conversions.

FAQ

Common causes include plugin conflicts, PHP errors, exceeded hosting limits, database issues, and security attacks. Monitoring helps you catch these quickly.

For business sites, check every 1-3 minutes. For personal blogs, every 5-15 minutes is usually sufficient. More frequent checks mean faster detection.

Yes. You can monitor wp-admin or wp-login.php separately. This ensures the backend is accessible even when the frontend works fine.
