Categories of terms
Requests
Request
A record of each request that has been processed through the Cloudflare network.
Origin requests
Requests served from the origin server.
Cached requests
The number of requests served from Cloudflare without having to hit the origin server. Cached requests are the sum of all requests where CacheCacheStatus equals hit, stale, updating, ignored. This does not include revalidated since the request had to be sent to the origin server.
Uncached requests
The number of requests that are not cached and therefore, are served from the origin server. Uncached requests are the sum of all requests where CacheCacheStatus does not equal to hit, stale, updating, or ignored.
Bandwidth
Total bandwidth (Total egress bandwidth, Edge bandwidth)
The amount of data transferred from Cloudflare to end users within a certain period of time. Total bandwidth equals the sum of all EdgeResponseBytes for a certain period of time.
Origin bandwidth (Origin egress bandwidth)
The amount of data transferred from the origin server to Cloudflare within a certain period of time. Origin bandwidth is the sum of all EdgeResponseBytes where OriginResponseStatus does not equal 0.
Cached bandwidth (Cached egress bandwidth)
The amount of bandwidth served from Cloudflare without hitting the origin server. Cached bandwidth is the sum of all EdgeResponseBytes where CacheCacheStatus equals hit, stale, updating, ignored, or revalidated.
Saved bandwidth (Saved egress bandwidth)
The percentage of bandwidth saved by caching on the Cloudflare network.
Uncached bandwidth (Uncached egress bandwidth)
The amount of bandwidth that is not cached and therefore, is served from the origin. Uncached bandwidth is the sum of all EdgeResponseBytes where CacheCacheStatus does not equal hit, stale, updating, ignored, or revalidated.
Website content
Static content
Website content that can be delivered to an end user directly from cache, without hitting the origin server.
Dynamic content
Website content that has to be fetched from the origin server.
HTTP Response codes
Edge response status code
HTTP response code sent from Cloudflare to the client (end user). The Cloudflare dashboard Analytics app uses the edge response status code.
Origin response status code
HTTP response code sent from the origin server to Cloudflare.
DNS
EDNS Client Subnet (ECS)
ECS is forwarded by recursive resolvers and contains information about the network that the DNS query is originating from. Not all resolvers choose to forward ECS, but if they do, usually a part of the IP address is omitted. The subnet length indicates the size of the client subnet in bits that is forwarded. So if the last octet of an IPv4 address is omitted (for example, 192.0.2.x.), the subnet length will be 24.
Threats
Threat
Any event that can potentially cause serious damage and lead to site attacks. In addition to threat analytics, you can monitor search engine crawlers visiting your websites. Cloudflare uses the IP reputation of a visitor to decide whether to present a challenge. A Cloudflare internal algorithm calculates an IP’s reputation and assigns a threat score that ranges from 0 to 100.
The security levels and the challenge display criteria are:
- High - for scores greater than 0
- Medium - for scores greater than 14
- Low - for scores greater than 24
- Essentially off - for scores greater than 49
Total Threats Stopped
Indicates the number of suspicious and bad requests aimed at your site.
Bad browser
This value results from the Cloudflare Browser Integrity Check (BIC) feature. It indicates that the source of the request was not legitimate or that the request itself was malicious. Users would see a Cloudflare error 1010 page in their browser. Cloudflare’s Browser Integrity Check looks for common HTTP headers used most often by spammers, and blocks access to your page. It also challenges visitors that do not have a user agent or use a non-standard user agent (commonly used by bots, crawlers, or visitors).
Blocked hotlink
This value results from the Cloudflare Hotlink Protection feature. Hotlink Protection ensures that other sites cannot use your bandwidth by building pages that link to images hosted on your server. Cloudflare customers can turn this feature on and off.
Bad IP
A request that came from an IP address that is not trusted by Cloudflare based on the Threat Score.
Country block
Requests from countries that were blocked based on the user configuration set in Cloudflare Firewall Rules.
IP block (user)
Requests from specific IP addresses that were blocked based on the user configuration set in Cloudflare Firewall Rules.
IP range block (/16)
A /16 IP range that was blocked based on the user configuration set in Cloudflare Firewall Rules.
IP range block (/24)
A /24 IP range that was blocked based on the user configuration set in Cloudflare Firewall Rules.
IPv6 block (user)
Requests from specific IPv6 addresses that were blocked based on the user configuration set in Cloudflare Firewall Rules.
IPv6 range block (/64)
A /64 IPv6 range that was blocked based on the user configuration set in Cloudflare Firewall Rules.
IPv6 range block (/48)
A /48 IPv6 range that was blocked based on the user configuration set in Cloudflare Firewall Rules.
IPv6 range block (/32)
A /32 IPv6 range that was blocked based on the user configuration set in Cloudflare Firewall Rules.
Captcha Error
Requests made by a bot that failed to pass the Captcha challenge.
New Captcha (user)
Challenge based on user configurations set for visitor’s IP in either the Web Application Firewall (WAF) or Cloudflare Firewall Rules.
Traffic
NoRecord
No record was found about this request/IP to classify it somewhere else.
Allowlist
The request has been sent from an allowlisted IP address.
SearchEngine
The search engine used to send the request.
BadHost
A bad host header or no host header was used.
Tor
The request was made using a Tor browser.
BadIP
A request coming from an IP address that is not trusted by Cloudflare based on the Threat Score.
WAF Events
Events that been triggered based on Web Applications Firewall rules.
