Site Sentinel: Your Website Says 200 OK. The Customers Disagree.

Описание и применение

Site Sentinel – инструмент MatrixSwarm для наблюдения за состоянием веб‑сайтов, проверяющий HTTP‑ответы, контент, зависимости, сертификаты и логи, предоставляя структурированные доказательства для расследования инцидентов.

Задача

A website reports 200 OK but customers see maintenance or broken pages, making it hard to detect real availability issues.

Результат

Site Sentinel provides structured evidence of website health, enabling precise incident investigation without performing remediation actions.

Рабочий процесс

• Install MatrixOS on the monitoring host or target server.
• Create a Swarm Workspace and add agents: site_sentinel, forensic_detective, matrix_https, matrix_websocket, log_streamer, and an alert relay.
• Configure Site Sentinel’s public and origin targets with URL, optional origin_url, host_header, expect marker, and note.
• Enable linked asset verification to sample up to 8 (configurable to 25) CSS/JS/image assets.
• Enable traffic analysis by listing access‑log files and setting thresholds for rate, distinct paths, and error ratio.
• Run Site Sentinel to collect evidence; review classifications such as PUBLIC_CONTENT_MISMATCH, PUBLIC_ASSET_FAILURE, ORIGIN_DEGRADED, EDGE_DEGRADED, SITE_UNAVAILABLE, PUBLIC_LATENCY, TLS_EXPIRING.
• Use Forensic Detective to investigate critical incidents and trigger alerts.
• Iterate by adding oracle analysis or adjusting thresholds as needed.
