order: 12

icon: lightbulb

一、环境

主机名	IP地址	系统	说明
localhost	192.168.11.61	Ubuntu 20.04	docker安装的prometheus
test	192.168.11.62	Ubuntu 20.04	rabbitmq版本3.7.15，Docker 版本 23.0.1

1、环境搭建

docker安装

略

docker-compose安装

略

rabbitmq

已在监控nginx那节课安装好

cd /data/rabbitmq

使用cat创建文件

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

运行

docker-compose up -d

二、监控rabbitmq

1、二进制安装（二选一）

rabbit_exporter下载地址: https://github.com/kbudde/rabbitmq_exporter/releases

下载二进制包解压并放入/opt目录

wget https://github.com/kbudde/rabbitmq_exporter/releases/download/v1.0.0-RC19/rabbitmq_exporter_1.0.0-RC19_linux_amd64.tar.gz

mkdir /opt/prometheus/rabbitmq_exporter -p

tar xvf rabbitmq_exporter_1.0.0-RC19_linux_amd64.tar.gz -C /opt/prometheus/rabbitmq_exporter

创建用户

useradd -M -s /usr/sbin/nologin prometheus

更改exporter文件夹权限

chown prometheus:prometheus -R /opt/prometheus

创建 systemd 服务

使用cat创建

cat > /etc/systemd/system/rabbitmq_exporter.service <<"EOF"
[Unit]
Description=prometheus rabbitmq exporter
After=network.target

[Service]
Environment=RABBIT_USER=guest
Environment=RABBIT_PASSWORD=guest
Environment=RABBIT_URL=http://localhost:15672
OUTPUT_FORMAT=JSON
Type=simple
User=prometheus
Group=prometheus
Restart=always
ExecStart=/opt/prometheus/rabbitmq_exporter/rabbitmq_exporter

[Install]
WantedBy=multi-user.target
EOF

启动

systemctl daemon-reload

systemctl start rabbitmq_exporter

加入到开机自启动

systemctl enable rabbitmq_exporter

检查

systemctl status rabbitmq_exporter

启动不了检查日志

journalctl -u rabbitmq_exporter.service -f

2、docker安装（二选一）

docker直接运行

docker run -d --restart=always -p 9419:9419  --name rabbitmq_exporter -e RABBIT_URL=http://192.168.11.62:15672 -e RABBIT_USER=guest -e RABBIT_PASSWORD=guest kbudde/rabbitmq-exporter

docker-compose方式

cat >docker-compose.yaml <<EOF
version: '3.3'
services:
  rabbitmq_exporter:
    image: kbudde/rabbitmq-exporter
    container_name: rabbitmq_exporter
    restart: always
    environment:
      RABBIT_URL: "http://192.168.11.62:15672"
      RABBIT_USER: "guest"
      RABBIT_PASSWORD: "guest"
      PUBLISH_PORT: "9419"
      OUTPUT_FORMAT: "JSON"
    ports:
      - "9419:9419"
EOF

启动

docker-compose up -d

检查

docker ps
或：
docker logs -f rabbitmq_exporter

3、参数解释

Environment variable	default	description
RABBIT_URL	http://127.0.0.1:15672	rabbitMQ管理插件的url（必须以http(s)://开头）
RABBIT_USER	guest	rabbitMQ 管理插件的用户名。
RABBIT_PASSWORD	guest	rabbitMQ 管理插件的密码。
OUTPUT_FORMAT	JSON	输出格式
PUBLISH_PORT	9419	运行端口(监听端口)

4、metrics地址

注：安装好Exporter后会暴露一个http://ip:端口/metrics的HTTP服务

名称	地址	备注
rabbitmq_exporter	http://192.168.11.62:9419/metrics

5、Prometheus配置

配置prometheus去采集（拉取）rabbitmq_exporter的监控样本数据

cd /data/docker-prometheus 

#在scrape_configs(搜刮配置):下面增加如下配置：

cat >> prometheus/prometheus.yml << "EOF"
  - job_name: 'rabbitmq_exporter'
    static_configs:
    - targets: ['192.168.11.62:9419']
      labels:
        instance: test服务器
EOF

重新加载配置

curl -X POST http://localhost:9090/-/reload

检查

6、常用的监控指标

rabbitmq_queue_messages_unacknowledged_global 队列中有未确认的消息总数（未被消费的消息）

rabbitmq_node_disk_free_limit  使用磁盘大小
rabbitmq_node_disk_free        磁盘总大小

rabbitmq_node_mem_used        使用内存大小
rabbitmq_node_mem_limit       内存总大小

rabbitmq_sockets_used         使用sockets的数量
rabbitmq_sockets_available    可用的sockets总数

rabbitmq_fd_used              使用文件描述符的数量
rabbitmq_fd_available         可用的文件描述符总数

7、触发器配置(告警规则)

Prometheus配置

# 报警(触发器)配置
rule_files:
  - "alert.yml"  
  - "rules/*.yml"

Rabbitmq触发器（告警规则）

也是单节点，未配置集群触发器

cat > prometheus/rules/rabbitmq.yml <<"EOF"
groups:
- name: Rabbitmq
  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: critical
    annotations:
      summary: "RabbitMQ有未确认消息,实例:{{ $labels.instance }}"
      description: 'RabbitMQ未确认消息>0,当前值为：{{ $value }}'      
  - alert: RabbitMQ可用磁盘空间不足告警
    expr: rabbitmq_node_disk_free_alarm != 0
    #expr: rabbitmq_node_disk_free_limit / rabbitmq_node_disk_free *100 > 90
    for: 0m
    labels:
      severity: critical
    annotations:
      summary: "RabbitMQ可用磁盘空间不足,实例:{{ $labels.instance }}"
      description: "RabbitMQ可用磁盘空间不足，请检查"
  - alert: RabbitMQ可用内存不足告警
    expr: rabbitmq_node_mem_alarm != 0
    #expr: rabbitmq_node_mem_used / rabbitmq_node_mem_limit * 100 > 90
    for: 0m
    labels:
      severity: critical
    annotations:
      summary: "RabbitMQ可用内存不足,实例:{{ $labels.instance }}"
      description: "RabbitMQ可用内存不足，请检查"
  - alert: RabbitMQ_socket连接数使用过高告警
    expr: rabbitmq_sockets_used / rabbitmq_sockets_available * 100 > 60
    for: 0m
    labels:
      severity: critical
    annotations:
      summary: "RabbitMQ_socket连接数使用过高,实例:{{ $labels.instance }}"
      description: 'RabbitMQ_sockets使用>60%,当前值为：{{ $value }}'
  - alert: RabbitMQ文件描述符使用过高告警
    expr: rabbitmq_fd_used / rabbitmq_fd_available * 100 > 60
    for: 0m
    labels:
      severity: critical
    annotations:
      summary: "RabbitMQ文件描述符使用过高,实例:{{ $labels.instance }}"
      description: 'RabbitMQ文件描述符使用>60%,当前值为：{{ $value }}'
EOF

检查：

vim prometheus/alert.yml

检查配置

docker exec -it prometheus promtool check config /etc/prometheus/prometheus.yml

重新加载配置

curl -X POST http://localhost:9090/-/reload

检查

http://192.168.11.61:9090/alerts?search=

或：

http://192.168.11.61:9090/rules
