This is a Prometheus exporter for Cloudflare's API. It uses the GraphQL API to fetch data from your account and expose it in a format that Prometheus can scrape.

• Modified the code structure.
• Removed cli dependency.
• Moved the collector to an specific file.
• You can choose the listening port using -prom-port.
• Now you can add multiple datasets like waf, http, workers, net or dns.
• If you have several zones but you only want to extract data from one of them you can use -zone to specify the name of the zone.
• The metrics are refreshed when the get request is received by prometheus exporter and not a fixed time, following the guidelines by Prometheus
• Modified "http" dataset to return more metrics
• Added "waf" dataset
• Added "workers" dataset
• Added "dns" dataset

• HTTP

  • Bytes (zoneName)

  • Request (zoneName)

  • CachedBytes (zoneName)

  • Bytes (contentType, zoneName)

  • Request (contentType, zoneName)

  • Bytes (country, zoneName)

  • Request (country, zoneName)

  • Threats (country, zoneName)

  • Bytes (cacheStatus, contentType, method, zoneName)

  • Requests (sslVersion, zoneName)

  • Requests (HTTPVersion, zoneName)

  • Requests (responseCode, zoneName)

• WAF

  • Events (action, asName, country, ruleID, zoneName)

• Workers

  • CPUTime
  • Errors
  • Requests
  • SubRequests

• DNS / DNS Firewall

  • Total Requests
  • Cached Requests
  • Staled Requests
  • Requests time (median,average, 90th percentile, 99th percentile)

• Network

  • Bits (attackID)
  • Packets (attackID)

Here is a sample of metric you should get once running and fetching from the API

go get -u github.com/neverlless/cloudflare_exporter

cloudflare_exporter -h
Usage of ./cloudflare_exporter:
  -account string
       Account ID to be fetched
  -dataset string
       The data source you want to export, valid values are: http, net, dns, workers, waf (default "http,waf")
  -email string
       The email address associated with your Cloudflare API token and account
  -key string
       Your Cloudflare API token
  -prom-port string
       Prometheus Addr (default "0.0.0.0:2112")
  -zone string
       Zone Name to be fetched

You can also use the following env variables instead of cli arguments:

• CF_KEY : Your Cloudflare API token
• CF_EMAIL : The email address associated with your Cloudflare API token and account
• CF_ACCOUNT : Account ID to be fetched
• CF_ZONE : Zone Name to be fetched
• CF_DATASET : The data source you want to export, valid values are: http, net, waf, workers, vnds, dns
• CF_PROM_PORT : Prometheus listening address

Once launched with valid credentials, the binary will spin a webserver on http://localhost:2112/metrics exposing the metrics received from Cloudflare's GraphQL endpoint.

• Add HealthCheck metrics
• Add DNS metrics
• Add DNS Firewall metrics
• Return old last scrapped metrics if time between scrappings is less than 5 min
• Refactorize
• Add Grafana Dashboards
• Add release binaries
