使用Prometheus和Grafana监控RabbitMQ集群 (使用RabbitMQ自带插件)

配置RabbitMQ集群

官方文档：https://www.rabbitmq.com/prometheus.html#quick-start

官方github地址：https://github.com/rabbitmq/rabbitmq-server

# 获取集群名称
rabbitmq-diagnostics -q cluster_status

# 设置集群名称
rabbitmqctl -q set_cluster_name myrabbitmq

# 启用插件
rabbitmq-plugins enable rabbitmq_prometheus

# 启用插件后的效果显示
rabbitmq-plugins enable rabbitmq_prometheus

Enabling plugins on node rabbit@ed9618ea17c9:
rabbitmq_prometheus
The following plugins have been configured:
  rabbitmq_management_agent
  rabbitmq_prometheus
  rabbitmq_web_dispatch
Applying plugin configuration to rabbit@ed9618ea17c9...
The following plugins have been enabled:
  rabbitmq_management_agent
  rabbitmq_prometheus
  rabbitmq_web_dispatch

started 3 plugins.

# 验证插件启用后的效果
curl -s localhost:15692/metrics | head -n 3  # 有密码的形式 curl -u username:password -s localhost:15692/metrics | head -n 3 （rabbitmq密码是访问15672使用的，访问15692不用密码）
# TYPE erlang_mnesia_held_locks gauge
# HELP erlang_mnesia_held_locks Number of held locks.
erlang_mnesia_held_locks{node="rabbit@65f1a10aaffa",cluster="rabbit@65f1a10aaffa"} 0

RabbitMQ 在专用 TCP 端口（默认为15692）上公开指标。

因此rabbitmq集群需要开放15692端口才行

配置prometheus

  - job_name: 'rabbitmq'
    static_configs:
      - targets: ['172.16.0.207:15692','172.16.0.84:15692','172.16.0.7:15692']
