Prometheus

В папке prometheus находится файл prometheus.yml. Просто собирает метрики со следующих таргетов:

• Сам Prometheus
• Grafana

global:
  scrape_interval: 15s
  scrape_timeout: 10s
  evaluation_interval: 15s
alerting:
  alertmanagers:
  - static_configs:
    - targets: []
    scheme: http
    timeout: 10s
    api_version: v2
scrape_configs:
- job_name: prometheus
  honor_timestamps: true
  scrape_interval: 15s
  scrape_timeout: 10s
  metrics_path: /metrics
  scheme: http
  static_configs:
  - targets:
    - localhost:9090
- job_name: grafana
  honor_timestamps: true
  scrape_interval: 15s
  scrape_timeout: 10s
  metrics_path: /metrics
  scheme: http
  static_configs:
  - targets:
    - grafana:3000
- job_name: otel-collector
  honor_timestamps: true
  scrape_interval: 15s
  scrape_timeout: 10s
  metrics_path: /metrics
  scheme: http
  static_configs:
  - targets:
    - otel-collector:8889

Grafana

Для автоматического добавления соседнего Prometheus в папке grafana расположен файл datasource.yml:

apiVersion: 1
 
datasources:
- name: Prometheus
  type: prometheus
  url: http://prometheus:9090 
  isDefault: true
  access: proxy
  editable: true
- name: Jaeger
  type: jaeger
  url: http://jaeger:16686
  access: proxy
  editable: true

Jaeger

В рамках стенда поднимается jaeger-all-in-one. Дополнительных настроек или файлов не требует.

OTEL collector

Настройки находятся в файле otel-collector-config.yaml:

receivers:
  otlp:
    protocols:
      grpc:
        endpoint: 0.0.0.0:4317
      http:
       endpoint: 0.0.0.0:4318
processors:
exporters:
  otlp:
    endpoint: "http://jaeger:4317"
    tls:
      insecure: true
  debug:
    verbosity: detailed
  prometheus:
    endpoint: 0.0.0.0:8889
service:
