Diagnose CDN business abnormal HTTP status codes (4xx/5xx) using hcloud CLI. Discover and quantify 4xx/5xx volume, localize the exact status code and time window, fork edge-generated vs origin-generated via back-to-source status statistics, correlate top-N distribution, narrow root cause on CDN edge config or origin side, and取证 per-request access logs. Use this skill when the user wants to: (1) diagnose CDN abnormal 4xx/5xx status codes, (2) root-cause a 403/404/5xx spike on a CDN domain, (3)…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# 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:
1. **Is there an anomaly, and how big?** — quantify 4xx/5xx volume and ratio over a window.
2. **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.
3. **Who / where / what path?** — top IPs/paths/UA/referer, client IP count (刷量 vs real users).
4. **Root cause + forensics?** — narrow to edge-config rules or origin-side issues, then pin the exact requests via access logs.
**Key Features:**
- Edge-vs-origin fork driven by one command (`bs_status_code_*`): `result={}` ⇒ edge-generated; non-empty ⇒ origin-generated.
- Covers the full 4xx/5xx set: 400/401/403/404/405/406/408/410/412/416/429/499/495/496/500/501/502/503/504/505/530….

How to install
mdr add huaweicloud/huaweicloud-skills/huawei-cloud-cdn-abnormal-status-code-analysis@sha256:bf7f26776cf92844The line at the top of this page pins the label git:20260929.e0ca07e, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
