Authentik

Prometheus Metrics

Authentik is an open-source identity provider that exposes native Prometheus metrics by default on port 9000.

Prometheus Metrics

Glouton Configuration

Prometheus metrics are available out of the box at http://localhost:9000/metrics. No service-side configuration is needed.

Linux

sudo tee /etc/glouton/conf.d/99-authentik.conf > /dev/null << 'EOF'
metric:
  prometheus:
    targets:
      - url: "http://localhost:9000/metrics"
        name: "authentik"
        allow_metrics:
          - "authentik_*"
          - "django_http_requests_total_by_method"
          - "django_http_responses_total_by_status"
          - "python_gc_objects_collected_total"
          - "process_resident_memory_bytes"
EOF

Windows

Create or edit C:\ProgramData\glouton\conf.d\99-authentik.conf:

metric:
  prometheus:
    targets:
      - url: "http://localhost:9000/metrics"
        name: "authentik"
        allow_metrics:
          - "authentik_*"
          - "django_http_requests_total_by_method"
          - "django_http_responses_total_by_status"
          - "python_gc_objects_collected_total"
          - "process_resident_memory_bytes"

If the metrics endpoint requires authentication in your setup, add an Authorization header to the target:

metric:
  prometheus:
    targets:
      - url: "http://localhost:9000/metrics"
        name: "authentik"
        headers:
          Authorization: "Bearer <your-api-token>"
        allow_metrics:
          - "authentik_*"
          - "django_http_requests_total_by_method"
          - "django_http_responses_total_by_status"
          - "python_gc_objects_collected_total"
          - "process_resident_memory_bytes"

Customize collected metrics

The metrics below are our recommended defaults. You can adjust the allow_metrics list to include any metric from Authentik’s monitoring documentation, or use deny_metrics to exclude specific ones. See Metrics Filtering for details.
