Prometheus 监控 Rabbitmq

这里只是对prometheus监控MySQL的配置过程做个记录，方便以后查阅。

1.下载rabbitmq_exporter

github地址：https://github.com/kbudde/rabbitmq_exporter/releases

[root@node1 prometheus]# wget https://github.com/kbudde/rabbitmq_exporter/releases/download/v1.0.0-RC7/rabbitmq_exporter-1.0.0-RC7.linux-amd64.tar.gz
[root@node1 prometheus]# tar xf rabbitmq_exporter-1.0.0-RC7.linux-amd64.tar.gz
[root@node1 prometheus]# mv -f rabbitmq_exporter-1.0.0-RC7.linux-amd64/ rabbitmq_exporter
[root@node1 prometheus]# cd rabbitmq_exporter

2.修改连接rabbitmq的配置文件

如果没有配置文件可以去github下载

[root@node1 prometheus]# cat config.json

{
    "rabbit_url": "http://127.0.0.1:15672",
    "rabbit_user": "admin",
    "rabbit_pass": "admin",
    "publish_port": "9419",
    "publish_addr": "",
    "output_format": "JSON",
    "insecure_skip_verify": false,
    "exlude_metrics": [],
    "include_queues": ".*",
    "skip_queues": "^$",
    "skip_vhost": "^$",
    "include_vhost": ".*",
    "rabbit_capabilities": "no_sort,bert",
    "enabled_exporters": [
            "exchange",
            "node",
            "overview",
            "queue"
    ],
    "timeout": 30,
    "max_queues": 0
}

主要修改以下配置：

rabbit_url：rabbitmq地址;
rabbit_user：mq的登录账户;
rabbit_pass：mq的账户密码;
publish_port：暴露监控指标的端口;
publish_addr：监控本机端口;

3.配置rabbitmq_exporter服务启动

添加到系统启动

[root@node1 rabbitmq_exporter]# cat /usr/lib/systemd/system/rabbitmq_exporter.service
[Service]
User=root
Group=root
ExecStart=/data/prometheus/rabbitmq_exporter/rabbitmq_exporter -config-file /data/prometheus/rabbitmq_exporter/config.json

[Install]
WantedBy=multi-user.target

[Unit]
Description=node_exporter
After=network.target

启动rabbitmq_exporter

[root@node1 rabbitmq_exporter]# systemctl enable rabbitmq_exporter 
[root@node1 rabbitmq_exporter]# systemctl start rabbitmq_exporter
[root@node1 rabbitmq_exporter]# systemctl status rabbitmq_exporter

4.修改prometheus配置

scrape_configs:
  - job_name: 'tst_wx1_108'
    scrape_interval: 5s
    scrape_timeout: 4s
    static_configs:
    - targets: ['172.20.190.108:9090','172.20.190.108:9100']
      labels: {cluster: 'tst',type: 'basic',env: 'tst',job: 'tst_wx1_108',export: 'prometheus'}
    - targets: ['172.20.190.108:9256']
      labels: {cluster: 'tst',type: 'process',env: 'tst',job: 'tst_wx1_108',export: 'process_exporter'}
    - targets: ['172.20.190.108:9419']
      labels: {cluster: 'tst',type: 'middle',env: 'tst',job: 'tst_wx1_108',export: 'rabbitmq_exporter'}

5.重启prometheus

如果开启了api管理功能，可以如下方式热加载配置

1	curl -X POST http://127.0.0.1:9090/-/reload

6.grafana出图

推荐使用4371

效果如下
