原文外掛簡介
Qndrs Availability and Heartbeat Monitor checks external URLs from the WordPress dashboard and can also monitor firewalled clients through outbound heartbeat pings. It supports multiple monitored URLs, per-URL monitoring toggles, email alerts, configurable Pushover alerts, status history, response times, uptime percentages, JSON import/export, structured logging, heartbeat monitors, and authenticated REST endpoints.
External services
This plugin can optionally send downtime and recovery notifications through Pushover. Pushover is disabled by default and is only used when a site administrator configures Pushover credentials and enables Pushover alerts for a monitor.
When Pushover is enabled, the plugin sends an HTTPS POST request to https://api.pushover.net/1/messages.json. The request contains the configured Pushover application token, the configured Pushover user or group key, and a notification title/message with the monitored URL or monitor name, status information, and HTTP status code or error message when available.

History Storage
Version 3.6.0 stores status history in an indexed custom database table. Fresh installations use the table directly. Existing installations with legacy option-based history can use the controlled WP-CLI migration documented in docs/history-storage.md, including count verification, shadow mode and rollback before finalization.
