prometheus.exporter.github

The prometheus.exporter.github component embeds the github_exporter for collecting statistics from GitHub.

Usage

Alloy
prometheus.exporter.github "<LABEL>" {
}

Arguments

You can use the following arguments with prometheus.exporter.github:

NameTypeDescriptionDefaultRequired
api_token_filestringFile containing API token to use to authenticate against GitHub.no
api_tokensecretAPI token to use to authenticate against GitHub.no
api_urlstringThe full URI of the GitHub API."https://api.github.com"no
github_app_idnumberThe GitHub App ID for authentication.no
github_app_installation_idnumberThe GitHub App installation ID for authentication.no
github_app_key_pathstringPath to the GitHub App private key file.no
github_rate_limitnumberThreshold for GitHub App rate limit to trigger re-authentication.15000no
organizationslist(string)GitHub organizations for which to collect metrics.no
repositorieslist(string)GitHub repositories for which to collect metrics.no
userslist(string)A list of GitHub users for which to collect metrics.no

Authentication

GitHub uses an aggressive rate limit for unauthenticated requests based on IP address. To allow more API requests, we recommend that you configure either token or GitHub App authentication.

  • Token authentication: Set api_token or api_token_file with a personal access token or classic token.
  • GitHub App authentication: Set github_app_id, github_app_installation_id, and github_app_key_path to authenticate as a GitHub App.

When provided, api_token_file takes precedence over api_token.

You can’t use both token authentication and GitHub App authentication simultaneously.

Blocks

The prometheus.exporter.github component doesn’t support any blocks. You can configure this component with arguments.

Exported fields

The following fields are exported and can be referenced by other components.

NameTypeDescription
targetslist(map(string))The targets that can be used to collect exporter metrics.

For example, the targets can either be passed to a discovery.relabel component to rewrite the targets’ label sets or to a prometheus.scrape component that collects the exposed metrics.

The exported targets use the configured in-memory traffic address specified by the run command.

Component health

prometheus.exporter.github is only reported as unhealthy if given an invalid configuration. In those cases, exported fields retain their last healthy values.

Debug information

prometheus.exporter.github doesn’t expose any component-specific debug information.

Debug metrics

prometheus.exporter.github doesn’t expose any component-specific debug metrics.

Examples

The following examples demonstrate token authentication and GitHub App authentication.

Token authentication

The following example uses a prometheus.scrape component to collect metrics from prometheus.exporter.github:

Alloy
prometheus.exporter.github "example" {
  api_token_file = "/etc/github-api-token"
  repositories   = ["grafana/alloy"]
}

// Configure a prometheus.scrape component to collect github metrics.
prometheus.scrape "demo" {
  targets    = prometheus.exporter.github.example.targets
  forward_to = [prometheus.remote_write.demo.receiver]
}

prometheus.remote_write "demo" {
  endpoint {
    url = "<PROMETHEUS_REMOTE_WRITE_URL>"

    basic_auth {
      username = "<USERNAME>"
      password = "<PASSWORD>"
    }
  }
}

Replace the following:

  • <PROMETHEUS_REMOTE_WRITE_URL>: The URL of the Prometheus remote_write compatible server to send metrics to.
  • <USERNAME>: The username to use for authentication to the remote_write API.
  • <PASSWORD>: The password to use for authentication to the remote_write API.

GitHub App authentication

The following example uses GitHub App authentication to collect metrics:

Alloy
prometheus.exporter.github "example" {
  repositories                 = ["grafana/alloy"]
  github_app_id                = 123456
  github_app_installation_id   = 789012
  github_app_key_path          = "/etc/github-app-key.pem"
}

// Configure a prometheus.scrape component to collect github metrics.
prometheus.scrape "demo" {
  targets    = prometheus.exporter.github.example.targets
  forward_to = [prometheus.remote_write.demo.receiver]
}

prometheus.remote_write "demo" {
  endpoint {
    url = "<PROMETHEUS_REMOTE_WRITE_URL>"

    basic_auth {
      username = "<USERNAME>"
      password = "<PASSWORD>"
    }
  }
}

Replace the following:

  • <PROMETHEUS_REMOTE_WRITE_URL>: The URL of the Prometheus remote_write compatible server to send metrics to.
  • <USERNAME>: The username to use for authentication to the remote_write API.
  • <PASSWORD>: The password to use for authentication to the remote_write API.
