安装Prometheus

安装Prometheus仅需在server1上安装。

  1. 进入Prometheus目录。 

    1
    		 
    cd /opt/prometheus/prometheus-2.45.4.linux-arm64/

  2. 配置prometheus.yml。

    1. 打开文件。 
      1
      		 
      vi prometheus.yml
    2. 按“i”进入编辑模式，配置为如下内容。

      # my global config
global:
  scrape_interval: 15s # Set the scrape interval to every 15 seconds. Default is every 1 minute.
  evaluation_interval: 15s # Evaluate rules every 15 seconds. The default is every 1 minute.
  # scrape_timeout is set to the global default (10s).
# Alertmanager configuration
alerting:
  alertmanagers:
    - static_configs:
        - targets:
          # - alertmanager:9093
# Load rules once and periodically evaluate them according to the global 'evaluation_interval'.
rule_files:
  # - "first_rules.yml"
  # - "second_rules.yml"
# A scrape configuration containing exactly one endpoint to scrape:
# Here it's Prometheus itself.
scrape_configs:
  # The job name is added as a label `job=<job_name>` to any timeseries scraped from this config.
  - job_name: "prometheus"
    # metrics_path defaults to '/metrics'
    # scheme defaults to 'http'.
    static_configs:
      - targets: ["localhost:9060"]
  - job_name: node_exporter
    honor_timestamps: true
    scrape_interval: 1s
    scrape_timeout: 1s
    metrics_path: /metrics
    scheme: http
    follow_redirects: true
    static_configs:
      - targets: ["agent1:9100","agent2:9100","agent3:9100"]
  - job_name: 'loads_metric'
    static_configs:
      - targets: ['server1:9090']
    metrics_path: '/loadIndicator/get/byCurrTimeForPrometheus'
    scheme: 'http'
    honor_labels: true
    scrape_interval: 1s
  - job_name: 'loads_metric_detail'
    static_configs:
      - targets: ['server1:9090']
    metrics_path: '/loadStatus/get/byCurrTimeForPrometheus'
    scheme: 'http'
    honor_labels: true
    scrape_interval: 1s

      若计算节点不为agent1/agent2/agent3，请按照实际集群规划修改如下行。

      1
      		 
      - targets: ["agent1:9100","agent2:9100","agent3:9100"]
    3. 按“Esc”键，输入:wq!，按“Enter”保存并退出编辑。

  3. 启动Prometheus。 

    1
    		 
    nohup ./prometheus --web.listen-address="0.0.0.0:9060" &

  4. 验证部署是否成功。 

    1
2
    		 
    # 调用接口
http://server1:9060/targets

    显示界面如上，loads_metric、loads_metric_detail以及node_exporter均为UP状态。

    在server1的LoadsMetricApplication进程和计算节点Node Exporter已启动的情况下，Prometheus界面如上接口应均为UP状态。

  5. 停止Prometheus服务。

    1. 找到Prometheus服务进程ID。 
      ps -aux | grep prometheus
    2. 使用Kill命令停止Prometheus。 
      kill ID
