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

说明与用途

Site Sentinel 是 MatrixSwarm 的工具，通过检查 HTTP 响应、必需内容、链接资源、TLS 证书、访问日志和主机资源，提供结构化证据以供事件调查。

问题

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

结果

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

工作流

• 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.
