Cloudflare

Introduction

Cloudflare is a Content Delivery Network (CDN) and cloud security platform that provides website optimization, security, and performance services. It acts as a mediator between a website’s server and its visitors, improving the speed and reliability of the website while also protecting it from online threats. Cloudflare can also as a reverse proxy for web traffic. It provides DDoS mitigation services that protect customers from Distributed Denial of Service (DDoS) attacks.

Discovery

The resources accessible through Cloudflare include the following:

• Cloudflare Account - An organization in Cloudflare is a logical grouping that allows for the management and segregation of resources within Cloudflare.
• Cloudflare Zone - Zone is the basic resource for working with Cloudflare and is equivalent to a domain name that the user purchases.
• Cloudflare Tunnel - A tunneling software that enables you to secure and encrypt application traffic for any type of infrastructure. It hides your web server IP addresses, blocks direct attacks, and helps you focus on delivering high-quality applications.

Cloudflare organizes its resources hierarchically to provide a topological view and simplify maintenance. The hierarchy of Cloudflare resources is as follows:

• Cloudflare Account
  • Cloudflare Zone
  • Cloudflare Tunnel

Monitoring

For monitoring Opsramp supports the following metrics list of Cloudflare:

Supported Metrics

Zone Discovery API

When a request is made to the zone discovery API for zone discovery, there are instances where the response time exceeds 30 seconds. In such scenarios, we halt the discovery process due to a potential issue with the Cloudflare API.

Graph Data Representation

For cloudflare_Zone_Threats, cloudflare_Zone_CachedBytes, cloudflare_Zone_BytesTransferred, and cloudflare_Zone_ResponseBodySize of zone native type metrics, the data that is timestamped one hour ago is displayed with the current timestamp at which data is collected. When a request is sent to the API within completion of an hour, the data may vary for the same timestamp until the current hour is complete. Once the hour is completed, the data becomes stable. After the hour is complete and the data is stable, data with the current timestamp is displayed. For information on rate limits for these metrics, see https://developers.cloudflare.com/analytics/graphql-api/limits/.
