Prpmetheus监控rabbitmq

启用一个rabbitmq docker 服务

cat >docker-compose.yaml<<'EOF'
 version: '3'
 services:
 rabbitmq:
   image: rabbitmq:3.7.15-management
   container_name: rabbitmq
   restart: always
   volumes:
     - /data/rabbitmq/data:/var/lib/rabbitmq
     - /data/rabbitmq/log:/var/log/rabbitmq
   ports:
     - 5672:5672
     - 15672:15672 
EOF

rabbitmq-exporter 启动

• 直接docker

docker run -d -p 9419:9419 --name rabbitmq_exporter \
 -e RABBIT_URL=http://10.19.1.220:15672 \
 -e RABBIT_USER=guest \
 -e RABBIT_PASSWORD=guest \
 kbudde/rabbitmq-exporter

• docker-compose 方式

cd /data/rabbitmq/

cat >docker-compose.yml << 'EOF'
version: '3.3'
services:
  rabbitmq_exporter:
    image: kbudde/rabbitmq-exporter
    container_name: rabbitmq_exporter
    restart: always
    environment:
      RABBIT_URL: "http://10.19.1.220:15672"
      RABBIT_USER: "guest"
      RABBIT_PASSWORD: "guest"
      PUBLISH_PORT: "9419"
      OUTPUT_FORMAT: "JSON"
    ports:
      - "9419:9419"
EOF

check

docker-compose up -d
docker ps 
docker logs -f rabbitmq_exporter
http://10.19.1.220:9419/metrics

Prometheus.yml 增加配置

cat >>prometheus/prometheus.yml << 'EOF'
  - job_name: 'rabbitmq_exporter'
    scrape_interval: 30s
    static_configs:
    - targets: ['10.19.1.220:9419']
      labels:
        instance: rabbitmq服务器
EOF

docker exec -it prometheus promtool check config /etc/prometheus/prometheus.yml
curl -X POST http://localhost:9090/-/reload

Rabbitmq触发器

cat >> prometheus/rules/rabbitmq.yml << 'EOF'
groups:

  rules:
  - alert: RabbitmqDown
    expr: rabbitmq_up != 1
    labels:
      severity: High
    annotations:
      summary: "Rabbitmq Down,实例:{{ $labels.instance }}"
      description: "Rabbitmq_exporter 连不上 Rabbitmq!!!!"
  - alert: Rabbitmq有未确认消息
    expr: rabbitmq_queue_messages_unacknowledged_global > 0
    for: 1m
    labels:
      severity: critital
    annotations:
      summary: "Rabbitmq有未确认消息,实例:{{ $labels.instance }}"
      description: "Rabbitmq有未确认消息>0,当前值: {{ $value }}"
