详情介绍:
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.
The monitor overview supports light, dark and system themes, configurable columns and a compact view. Display preferences are remembered in this browser for each site and WordPress user, including during automatic refresh. Status, monitor names and management actions remain available.
安装:
- Upload the plugin folder to
/wp-content/plugins/qndrs-availability-heartbeat-monitor. - Activate Qndrs Availability and Heartbeat Monitor from the WordPress plugins page.
- Open Qndrs Monitor > Overview in the WordPress admin menu. Use Qndrs Monitor > Settings for configuration.
- Add one or more URLs and choose notification channels.

常见问题:
How do I configure Pushover?
Configure Pushover credentials from the plugin settings page. Stored credentials are masked and are not included in JSON exports.
You can also add these constants to wp-config.php; constants take precedence over stored settings:
define('PUSHOVER_USER_KEY', 'your-user-key');
define('PUSHOVER_API_TOKEN', 'your-api-token');
Where are logs stored?
Logs are stored in the WordPress database option qndrs_ahm_logs and capped to avoid unbounded growth. The REST log endpoint supports type, url, date_from, date_to, page, per_page, limit, and order query parameters.
Is the REST endpoint public?
No. REST endpoints require a user with the manage_options capability or the plugin read-only API token.
How do heartbeat monitors work?
Create a heartbeat monitor from the settings page. The plugin shows a one-time token and curl example. A client sends outbound HTTPS POST requests to /wp-json/qndrs-availability-heartbeat-monitor/v1/heartbeat; the monitor becomes stale/down when no ping arrives in time.
Detailed heartbeat client examples are included in docs/heartbeat-monitors.md. Dutch documentation is included in docs/heartbeat-monitors.nl.md.
