A lightweight WordPress node agent that reports uptime and health to a Central dashboard you configure.

== Description ==
Zubbin Node Agent runs inside WordPress and reports:

* Heartbeat status to Central
* Tier-1 health: fatal error capture, WP-Cron health
* Tier-2 health: database connectivity, REST loopback health
* Optional webhook push (enabled by default)

Alerts (email/webhook/SMS) are configured and sent by Zubbin Central.

To use centralized monitoring, configure your Central URL and onboard this node.

== External Services ==
This plugin can send data to a Central endpoint (the URL you enter in settings). That endpoint may be self-hosted by you or provided by zubbin.com.

Data sent may include:
* Site URL and site name
* Node identifier assigned by Central (node_key)
* Monitoring status and health check results (cron, database, REST/loopback, recent fatal summary)
* Plugin version

This service is optional. The plugin remains functional without connecting to the service.

== Frequently Asked Questions ==
= Do I need a Central dashboard? =
You can run the plugin locally, but centralized alerting requires a Central endpoint to receive heartbeats.

No. Alerts are sent by Zubbin Central.
