Monitoring shouldn't require a dedicated team to run the monitoring. Xitoring consolidates server monitoring, uptime checks, SSL tracking, cron/heartbeat monitoring, and status pages into one platform with one lightweight agent. Install is a single command (curl on Linux, MSI on Windows). The Xitogent agent auto-detects what's running — Nginx, Apache, IIS, MySQL, PostgreSQL, MongoDB, Redis, Docker, RabbitMQ, Kafka, HAProxy, and 30+ other services — and starts collecting metrics without manual configuration. Uptime checks (HTTP(S), Ping, DNS, TCP, UDP, API, Mail, FTP, Heartbeat, Cron) run at 1-minute intervals from 15+ global probing nodes, so one flaky route doesn't page you at 3 AM. Alert routing covers 20+ channels, from the usual (email, Slack, Teams, PagerDuty, Opsgenie, webhooks) to the ones your on-call actually answers (SMS, phone call, WhatsApp, Telegram). The differentiator: Xitoring ships an MCP server. Connect Claude, Cursor, or any MCP-compatible agent and your AI tooling gets the same access as the web panel — read metrics, inspect incidents, ack alerts, create and modify monitors. The built-in AIOps assistant answers plain-English questions ("what changed in the last hour?", "top 5 RAM-hungry hosts this week") against your real telemetry instead of generic advice. Also included: white-label status pages on your own domain, incident management with root-cause context, REST API, and native iOS/Android apps. Pricing is flat and public. Free forever for 2 servers and 8 uptime checks; paid from $4.99/month. No per-metric billing, no per-seat surprises, no "contact sales."
