Prometheus GitHub vulnerability alert exporter

This package exports the Security Vulnerability Alerts from GitHub for all repositories of an organization as Prometheus metrics.

Usage

Configure API token

You'll need to provide an access token with scope repo to access the GitHub API. See the GitHub documentation for details.

Start HTTP service

Start the HTTP server like this:

$ GITHUB_AUTHTOKEN=MYTOKEN GITHUB_OWNER=MyGitHubOrgOrUser github_vulnerability_exporter --host=127.0.0.1 --port=9597

Pass --ttl=SECONDS to cache GitHub API results for the given time or -1 to disable (default is 600). Prometheus considers metrics stale after 300s, so that's the highest scrape_interval one should use. However it's usually unnecessary to hit the API that often, since the vulnerability alert information does not change that rapidly.

Pass --forked if you want to include forked repositories (not sure if they actually receive vulnerability alerts, though).

Configure Prometheus

scrape_configs:
  - job_name: 'vulnerabilities'
    scrape_interval: 300s
    static_configs:
      - targets: ['localhost:9597']

We export one metric, a gauge called github_vulnerability_alerts, with labels {repository="MyGitHubOrgOrUser/my-repository-name, status="active|dismissed"}.

Additionally, a ghvuln_scrape_duration_seconds gauge is exported.
