Prometheus 使用blackbox_exporter和rabbitmq_exporter

第1章 部署blackbox_exporter

1.1下載地址：

https://github.com/prometheus/blackbox_exporter

1.2解壓後修改blackbox.yml配置文件

modules:

  http_2xx:

    prober: http

    http:     #下面兩個參數要加上，表示支持http版本和http狀態碼的監控

     valid_http_versions: ["HTTP/1.1", "HTTP/2"]

     valid_status_codes: [200]

      method: GET

      preferred_ip_protocol: "ip4"

 http_post_2xx:

    prober: http

    http:

      method: POST

     preferred_ip_protocol: "ip4"

 tcp_connect:

    prober: tcp

 pop3s_banner:

    prober: tcp

    tcp:

     query_response:

      - expect: "^+OK"

      tls: true

     tls_config:

       insecure_skip_verify: false

  ssh_banner:

    prober: tcp

    tcp:

     query_response:

      - expect: "^SSH-2.0-"

  irc_banner:

    prober: tcp

    tcp:

     query_response:

      - send: "NICK prober"

      - send: "USER prober prober prober :prober"

      - expect: "PING :([^ ]+)"

        send: "PONG ${1}"

      - expect: "^:[^ ]+ 001"

  icmp:

prober: icmp

1.3啓動命令：

./blackbox_exporter --config.file=./blackbox.yml

第2章 修改promethus主配文件：

  - job_name: 'http-status-test'

    scrape_interval: 30s #每次獲取數據的時間間隔

   metrics_path: /probe

    params:

      module: [http_2xx]

   static_configs:

      - targets:

        - http://jiang.test.com

        - http://www.baidu.com

   relabel_configs:

      - source_labels: [__address__]

       target_label: __param_target

      - source_labels: [__param_target]

       target_label: instance

      - target_label: __address__

       replacement: 10.133.201.127:9115

2.1在promethusUI界面上查看監控數據

第3章 部署rabbitmq_exporter

3.1下載rabbitmq_exporter

wget https://github.com/kbudde/rabbitmq_exporter/releases/download/v0.29.0/rabbitmq_exporter-0.29.0.linux-amd64.tar.gz

3.2解壓

tar xf rabbitmq_exporter-0.29.0.linux-amd64.tar.gz

3.3運行rabbitmq時須要加上幾個環境變量

PUBLISH_PORT=9990 RABBIT_URL="http://localhost:15672" RABBIT_CAPABILITIES="no_sort,bert" ./rabbitmq_exporter

3.4出現一下信息證實promethus鏈接rabbitmq_exporter正常

INFO[0000] Using default certificate pool

INFO[0011] Metrics updated                              duration=17.240458ms

3.5將rabbitmq_exporter註冊到consul

curl -H "Content-Type: application/json" -XPUT http://10.133.201.127:8500/v1/agent/service/register -d '{"ID":"rabbitmq_exporter_1","Name": "rabbitmq_exporter","Tags": ["rabbitmq_export"],"Address": "10.3.2.15","Port": 9419,"EnableTagOverride": false,"Check": {"Name": "rabbitmq_export on port 9419","TCP":"10.3.2.15:9419","Interval": "10s","Timeout": "1s"}}'

3.6登陸到rabbitmq上添加隊列測試監控數據是否正常

3.7web頁面查看監控數據
