HTTP Monitoring

Each monitor performs an HTTP/HTTPS request to your endpoint at a configurable interval. Every probe captures:

• Full timing breakdown — DNS lookup, TCP connect, TLS handshake, send, wait (TTFB), and receive phases.
• HTTP headers & body — Request and response headers plus truncated body (1 KB) captured on every probe.
• TCP metrics — Kernel-level TCP_INFO data including RTT, retransmits, congestion window, and segment counters.
• Packet capture — Optional per-probe pcap of the full HTTP exchange (SYN to FIN) for deep post-mortem analysis.

Monitors support custom HTTP methods (GET, POST, HEAD, etc.), custom headers, request body, and configurable timeouts. Check intervals range from 30 seconds (Business) to 5 minutes (Free).
