What is this repository for?

This is a Prometheus Exporter/Collector for Edgecast CDN.

Exporter-Edgecast uses the edgecast-client created by Matthias Endler to fetch metrics from the EdgeCast CDN API and then transforms and exposes them to be scraped and displayed by Prometheus.

Package Management

  • This project uses dep as package manager
  • versions are tracked in Gopkg.lock
  • glide settings are included in Gopkg.toml
  • get dep here: https://github.com/golang/dep

Static Analysis

  • make lint (uses gometalinter, downloads and installs it in case of absence)


  • make build (builds for Windows or Unix, after checking $(OS),Windows_NT)


  • You need to set two environment-variables to configure your Edgecast-Account:
  • e.g. on Linux: export EDGECAST_TOKEN=B12AC
  • Optionally, you can also configure the queried platforms (see below for possible values), e.g.:


  • ./bin/main (Unix) or .\bin\main.exe (Windows)
  • via Docker:
    • build Docker image: make docker
    • run Docker image: (sudo) docker run -p=<some_free_port>:80 trivago/monitoring:edgecast-v1 -e "EDGECAST_TOKEN=<your_token>" -e "EDGECAST_ACCOUNTID=<your_id>"
      • NOTE: <some_free_port> must be the same as specified in the job-description in prometheus.yml

View Exposed Metrics:

  • via Browser on the same machine: visit http://localhost:80/metrics
    • via Browser on different machine: change "localhost" to endpoint address
  • via existing Prometheus server installation:
    • start new server locally using the provided configuration file:
    • copy & paste job from provided prometheus.yml to running server's configuration to scrape the service metrics
