CDN Abnormal Status Code Analysis
Overview
This skill diagnoses abnormal HTTP status codes (4xx / 5xx) on a Huawei Cloud CDN accelerated domain. It is read-only end to end: every action is a query (GET statistics / GET config / GET log-download-link / read-only log fetch). It answers four questions for any 4xx/5xx anomaly:
- Is there an anomaly, and how big? — quantify 4xx/5xx volume and ratio over a window.
- Which exact code, when, edge or origin? — drill to the specific code + time bucket, and fork edge-generated vs origin-generated via the back-to-source (
bs_*) status statistics. - Who / where / what path? — top IPs/paths/UA/referer, client IP count (刷量 vs real users).
- Root cause + forensics? — narrow to edge-config rules or origin-side issues, then pin the exact requests via access logs.
