What PHP Server Monitor is

PHP Server Monitor is a free, self-hosted web script for checking whether websites and servers are available. It can connect to an IP address or domain on a selected port, or inspect a website’s HTTP status and compare page content with a regular expression; a failed check marks the site down. Cron jobs can run checks automatically. Alerts are available through email, SMS, Discord, Pushover, Telegram, and Jabber. Listed SMS gateways include Twilio, Plivo, Nexmo, and MessageBird, which require accounts with sufficient credits. Uptime and latency graphs show history, while optional logs record connection errors, outgoing emails, and text messages. Administrator and regular-user roles support controlled access and per-server user management. Deployment requires a web server, MySQL, PHP 7.4 or later, and specified PHP extensions. Releases are provided through GitHub, with older versions on SourceForge; Docker is also described.

Verdict
