Summary

Cloudflare is a content delivery network (CDN) that helps businesses accelerate, protect, and optimize their websites, applications, and APIs. It acts as a reverse proxy, sitting between users and a website’s origin server to provide DDoS protection, web application firewall (WAF), CDN caching, and load balancing. Cloudflare logs contain a wealth of information that can be utilized for various purposes such as debugging and troubleshooting, managing cost, security monitoring, compliance and auditing, and more. The anatomy of a Cloudflare log includes fields like EdgeStartTimestamp, EdgeEndTimestamp, ClientRequestQuery, EdgeResponseStatus, CacheStatus, OriginIP, OriginTLSVersion, OriginResponseDurationMs, WAFAction, BotScore, ThreatScore, ASN, ClientSSLProtocol, and ClientCipher. By analyzing these fields, teams can differentiate between origin server issues and Cloudflare-related errors, detect routing, caching, or security rule misconfigurations, optimize usage and reduce unnecessary costs, monitor security events, detect threats, and ensure compliance with regulatory requirements. Cloudflare logs can be monitored with Datadog's Cloudflare integration, which enables streaming of logs into Datadog Log Management and offers out-of-the-box dashboards for metric and log monitoring. Additionally, Datadog provides tooling for users to monitor Cloudflare load balancers, helping ensure dependable traffic throughput.
