node-exporter 收集数据

docker run -d -p 9100:9100 -v "/proc:/host/proc:ro" -v "/sys:/host/sys:ro" -v "/:/rootfs:ro" node-exporter:v1.0

检查端口是否正常

lsof -nP -i:9100

正常！

prometheus监控搭建

mkdir -p  /app/prometheus
cd  /app/prometheus/
vim  prometheus.yml

已经将node_export 搭建并配置完成了，而prometheus是 通过node_export接口进行数据收集的，所以我们需要将 node_export 加入到prometheus监控中，配置信息如下：

# 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:9090"]
  - job_name: "node_export"

    # metrics_path defaults to '/metrics'
    # scheme defaults to 'http'.

    static_configs:
      - targets: ["192.168.111.101:9100"]

targets: ['192.168.111.101:9100'] 就是将我们上面搭建的node_export加入prometheus监控的
不能使用 localhost+端口
不然报错 Get “http://localhost:9100/metrics”: dial tcp 127.0.0.1:9100: connect: connection refused

启动容器

docker run -d -p 9090:9090 -v /app/prometheus/prometheus.yml:/etc/prometheus/prometheus.yml prometheus:v1.0

grafana数据可视化

mkdir  -p  /app/grafana-storage 
cd  /app/grafana-storage 
chmod 777 -R  /app/grafana-storage 

# 启动容器
docker run -d -p 3000:3000 --name=grafana  -v  /app/grafana-storage/:/var/lib/grafana  grafana:v1.0
