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. Pushover API documentation: https://pushover.net/api Pushover terms: https://pushover. net/terms Pushover privacy policy: https://pushover.net/privacy ### 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. ## 屏幕截图 [⌊Availability overview with uptime checks and heartbeat monitor status.⌉⌊Availability overview with uptime checks and heartbeat monitor status.⌉[ Availability overview with uptime checks and heartbeat monitor status.

Upload the plugin folder to `/wp-content/plugins/qndrs-availability-heartbeat-monitor`. 2. Activate Qndrs Availability and Heartbeat Monitor from the WordPress plugins page. 3. Open Qndrs Monitor in the WordPress admin menu. 4. Add one or more URLs and choose notification channels. For more reliable checks, configure a real server cron to call `wp-cron.php`. ## 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`. ## 评价 此插件暂无评价。 ## 贡献者及开发者 「Qndrs Availability and Heartbeat Monitor」是开源软件。 以下人员对此插件做出了贡献。 贡献者 * [ Qndrs ](https://profiles.wordpress.org/qndrs/) 「Qndrs Availability and Heartbeat Monitor」插件已被翻译至 1 种本地化语言。 感谢 [所有译者](https://translate.wordpress.org/projects/wp-plugins/qndrs-availability-heartbeat-monitor/contributors) 为本插件所做的贡献。 [帮助将「Qndrs Availability and Heartbeat Monitor」翻译成简体中文。](https://translate.wordpress.org/projects/wp-plugins/qndrs-availability-heartbeat-monitor) ### 对开发感兴趣吗? 您可以[浏览代码](https://plugins.trac.wordpress.org/browser/qndrs-availability-heartbeat-monitor/)， 查看[SVN仓库](https://plugins.svn.wordpress.org/qndrs-availability-heartbeat-monitor/)， 或通过[RSS](https://plugins.trac.wordpress.org/log/qndrs-availability-heartbeat-monitor/?limit=100&mode=stop_on_copy&format=rss) 订阅[开发日志](https://plugins.trac.wordpress.org/log/qndrs-availability-heartbeat-monitor/)。 ##
