Accelvia Uptime Monitor vs Smush – Image Optimization, Compression, Lazy Load, WebP & CDN

Accelvia Uptime Monitor turns your WordPress installation into a self-hosted website monitoring system. Instead of relying on external SaaS platforms, this plugin uses your local WordPress database to store uptime logs and performance metrics directly on your server. The plugin features a Dual-Layer Architecture: WordPress handles local analytics (HTML parsing, SSL certificate inspection), and optionally synchronizes with an external Edge Network. If your WordPress server goes offline, the external “Deadman’s Switch” detects the failure and sends alerts independently. Key Features Dual-Layer Monitoring: The plugin monitors your site locally via WordPress cron. Optionally, an external Edge Fallback (Deadman’s Switch) can detect total server failures and send alerts even when your WordPress installation is unreachable. Self-Hosted Data Storage: All historical analytics, ping logs, and configuration data are stored in your own WordPress database. No external accounts or subscriptions are required for core monitoring. SSL Certificate Tracking: During each monitoring cycle, the plugin inspects the SSL/TLS certificate of your site and calculates the remaining days until expiration. It sends warning alerts at 7 days, 3 days, and 1 day before expiry. Defacement and Crash Detection: You can configure a “Master Keyword” that must be present in your site’s HTML output. If the keyword is missing (indicating a white screen, database error, or content tampering), the plugin marks the site as down. Multi-Channel Alerting: Route alerts and periodic summary reports to Email, Slack, Discord, Telegram, and WhatsApp simultaneously. All channels are configured from the plugin settings page. Additional Capabilities Edge Fallback (Deadman’s Switch): An optional external cloud service that continuously polls your site. If WordPress becomes completely unreachable, the external service sends alerts on your behalf. SSL Expiry Countdown: Automatically dispatches alerts at 7-day, 3-day, and 1-day intervals before your SSL certificate expires. Keyword-Based Content Verification: Verifies that specific content exists in your page’s HTML source, catching silent failures that return HTTP 200 but serve broken content. Local Analytics Logging: Stores all monitoring data in your WordPress MySQL database with configurable retention periods. PageSpeed Insights Integration: Queries Google’s PageSpeed Insights API daily to track Desktop and Mobile performance scores over time. Configuration: Server-Side Cron By default, WordPress relies on “simulated cron” (WP-Cron), which only fires when a user visits your website. If your site receives low traffic, your uptime checks may be delayed. For accurate monitoring intervals, consider disabling default WP-Cron and setting up a server-side cron job (via cPanel or your hosting dashboard) to execute wp-cron.php every 5 minutes. This ensures the monitoring engine executes on schedule regardless of website traffic. External Services This plugin connects to the following third-party and external services. Each service is used only when the corresponding feature is enabled and configured by the site administrator. Accelvia API Proxy (Edge Fallback / Deadman’s Switch) When the “Edge Fallback” feature is enabled in Settings, the plugin sends your monitored URLs, site identifier hash, and configured alert channel credentials to an external proxy service hosted on Vercel. This proxy independently pings your site and sends alerts if your WordPress server becomes completely unreachable. Service URL: https://accelvia-api-proxy.vercel.app Data sent: Monitored URLs, a hashed site identifier, and alert channel configuration (webhook URLs, API tokens). When sent: Each time settings are saved with Edge Fallback enabled, and during scheduled sync cycles.

Service URL: https://www.googleapis.com/pagespeedonline/v5/runPagespeed Data sent: The monitored URL and optionally a user-provided API key. When sent: Once daily via WordPress scheduled cron, and on manual sync. Service provider: Google LLC Google Terms of Service: https://policies.google.com/terms Google Privacy Policy: https://policies.google.com/privacy Domain Registration Expiry Check (RDAP Protocol) The plugin’s daily security scan checks the domain registration expiration date of each monitored site using RDAP (Registration Data Access Protocol), the official successor to WHOIS as designated by ICANN. RDAP queries are sent directly to the authoritative domain registry for each supported TLD. Data sent: The domain name of each monitored URL. When sent: Once daily during the scheduled security scan. Supported TLDs and their authoritative RDAP servers: .com / .net domains are queried via Verisign (https://rdap.verisign.com) .org domains are queried via Public Interest Registry / PIR (https://rdap.publicinterestregistry.org) Protocol specification: RDAP is an IETF/ICANN standard (RFC 9082, RFC 9083).
