Monitoring API disini menggunakan beberapa services seperti Grafana (Visualiasi & Anomali Detector), Prometheus (Database), Blackbox Exporter (Sensor Pengumpul Data) dan Hermes (Send Notification ke Broker). Poin inti dari Monitoring API ini adalah :
- API Status
- API Response Time dan Latency
- Mengembalikan response yang tidak sesuai
Beberapa services tersebut dijalankan diatas docker dan berikut file konfigurasi yang perlu disiapkan.
1. Example konfigurasi Blacbox Exporter untuk method GET API (blackbox_expoter.yml).
modules: http-2xx-get-token: prober: http timeout: 15s http: valid_http_versions: ["HTTP/1.1", "HTTP/2"] valid_status_codes: [200] method: GET headers: Authorization: Bearer <Token> no_follow_redirects: false fail_if_ssl: false fail_if_not_ssl: false tls_config: insecure_skip_verify: false preferred_ip_protocol: "ip4"
2. Example konfigurasi Prometheus sebagai Data Source (prometheus.yml) dan service docker compose disini.
