Z UpTime by Zubbin – Uptime & Site Health Monitoring
Most uptime tools only ping your homepage from the outside. By the time they notice a problem, your visitors have already hit a white screen and left. Z UpTime is different: it runs inside WordPress, so it sees the things an external ping never can — a plugin update that triggered a fatal error, WP-Cron that silently stopped running, a database that stopped responding, or the REST API going dark.
Z UpTime is the official WordPress connector for the Zubbin monitoring platform. Install it, pair it with your free Zubbin account, and your site continuously reports its real health so you (and your whole fleet, if you run more than one site) get alerted the moment something breaks — often before it becomes downtime.
Free to install. Free plan available. External uptime checks and core health reporting are free forever. Paid Zubbin plans add faster check intervals, more sites, longer history, and richer WordPress-specific alerts.
Why “from the inside” matters
An outside pinger can only tell you that your homepage returned an error. Z UpTime tells you what actually happened, because it’s running where the problem is:
- Fatal error / white-screen capture — records the file, line, and message of the last PHP fatal, so a bad plugin update doesn’t leave you guessing.
- WP-Cron health — flags when scheduled tasks stop firing (a silent killer of backups, emails, and orders).
- Database reachability — a real
SELECT 1from inside WordPress, not a guess from the HTTP status code. - REST API loopback — confirms
/wp-json/is actually responding, not just that the front page loads.
What it does
- Periodic heartbeat so Zubbin knows your site is up (scheduled via WP-Cron).
- Health snapshot on every heartbeat: last fatal error, last cron tick, database check, REST check, and response time.
- Inventory reporting: WordPress version, PHP version, active theme, and installed plugins — including which ones have updates available, so you can spot out-of-date, vulnerable components across every site.
- Self-pairing onboarding and a clear connection/status screen inside wp-admin.
- Fleet-friendly: manage one site or a hundred from a single Zubbin dashboard — built for agencies and site maintainers.
Monitoring, alerting, dashboards, incident history, and billing live in your Zubbin account (by default at https://app.zubbin.com). This plugin is the lightweight reporting node that makes that possible.
External services
This plugin connects to Zubbin, an external service operated by Zubbin, to provide monitoring. This connection is required for the plugin to function. By default it talks to https://app.zubbin.com; you can point it at a different Zubbin server in the plugin settings.
What is sent, and when:
- On pairing / registration: site URL, site name, administrator email, WordPress version, PHP version, plugin version, and environment type.
- On each heartbeat (scheduled via WP-Cron): an up/down status, response time, and a health/inventory snapshot — WordPress/PHP versions, active theme, installed plugins and their versions/available updates, database/REST/cron health, and whether a recent fatal error occurred.
No site content, post data, passwords, or visitor personal data is collected or transmitted.
