⏳ End-of-Life Exporter

A Prometheus exporter that exposes product versions and their End-of-Life (EOL) dates as metrics using the endoflife.date API. Information is fetched only when Prometheus scrapes the /metrics endpoint.

⚙️ Configuration

Configure products and their release cycles as shown below.

💡 Always verify product names on endoflife.date. If you don't specify a release, it defaults to the latest available one.

---
products:
  - name: mongo
    releases:
      - "8.0"

🔥 Prometheus Configuration

Below is an example scrape configuration for Prometheus.

---
scrape_configs:
  - job_name: "endoflife_exporter"
    scrape_interval: 168h # Every week
    scrape_timeout: 2m # If you have a long list of products, you might want to increase the timeout.
    static_configs:
      - targets: ["endoflife_exporter:8080"]

Alerting Rules Example

groups:
  - name: endoflife.rules
    rules:
      - alert: ProductVersionEOLReachingSoon
        expr: avg by (product_name, release_cycle_name) (endoflife_eol_from_timestamp_seconds - time()) < (21 * 24 * 3600)
        for: 1h
        labels:
          severity: error
        annotations:
          message: 'Product ''{{ $labels.product_name }}'' release cycle ''{{ $labels.release_cycle_name }}'' reached its End-of-Life on {{ ($value | timestamp "2006-01-02") }}.'

📊 Metrics

Here are some example metrics exposed by the exporter:

# HELP endoflife_eol_from_timestamp_seconds Unix timestamp when a product's release cycle reaches its End-of-Life (EOL) or maintenance end.
# TYPE endoflife_eol_from_timestamp_seconds gauge
endoflife_eol_from_timestamp_seconds{product_name="mongo",release_cycle_name="8.0"} 0

# HELP endoflife_latest_version_timestamp_seconds Unix timestamp of the latest version release date for a product's release cycle.
# TYPE endoflife_latest_version_timestamp_seconds gauge
endoflife_latest_version_timestamp_seconds{product_name="mongo",release_cycle_name="8.0"} 1.7527104e+09

# HELP endoflife_product_info Information about the End-of-Life (EOL) status and details of a product.
# TYPE endoflife_product_info gauge
endoflife_product_info{is_eol="false",is_lts="false",is_maintained="true",latest_version="8.0.12",product_name="mongo",release_cycle_name="8.0"} 1

# HELP endoflife_release_cycle_timestamp_seconds Unix timestamp of the release cycle's official release date.
# TYPE endoflife_release_cycle_timestamp_seconds gauge
endoflife_release_cycle_timestamp_seconds{product_name="mongo",release_cycle_name="8.0"} 1.7278272e+09
