Synthetic Probes and API Metrics

These examples cover synthetic probes and API-backed exporters. They are great for checking uptime and collecting third-party stats.

Example: Blackbox Probes (Synthetic Monitoring)​

06-blackbox.alloy
prometheus.exporter.blackbox "local" {
  config = "{ modules: { http_2xx: { prober: http, timeout: 5s } } }"

  target {
    name    = "techbloomeracademy"
    address = "https://techbloomeracademy.com"
    module  = "http_2xx"
  }

  target {
    name    = "gobotify"
    address = "https://gobotify.com"
    module  = "http_2xx"
  }
}

// Configure a prometheus.scrape component to collect blackbox metrics.
prometheus.scrape "demo" {
  targets    = prometheus.exporter.blackbox.local.targets
  forward_to = [prometheus.relabel.common_labels.receiver]
}

Example: GitHub Repository Metrics​

11-github.alloy
// 11-github.alloy

prometheus.exporter.github "my_github_stats" {
  api_token = sys.env("GITHUB_TOKEN")
  repositories   = ["learnwithvikasjha/tba-docs","learnwithvikasjha/gobotify"]

}

discovery.relabel "github_relabel" {
  targets = prometheus.exporter.github.my_github_stats.targets
  rule {
    target_label = "job"
    replacement  = "integrations/github"
  }
}

prometheus.scrape "github_scrape" {
  targets    = discovery.relabel.github_relabel.output
  forward_to = [prometheus.relabel.common_labels.receiver]
}
tip

Store your GITHUB_TOKEN as an environment variable so it is not committed into config files.
