1 前言

本文将使用docker搭建普罗米修斯可视化监控环境，安装组件包括：Influx、Prometheus、Grafana，并基于该环境进行Substrate节点可视化监控。

2 操作步骤

2.1 Promethues配置

# prometheus.yml 
global:
  scrape_interval:     15s 
  evaluation_interval: 15s

scrape_configs:
  - job_name: 'prometheus'
    static_configs:
    - targets: ['localhost:9090']

  - job_name: 'js_substrate_node'
    scrape_interval: 5s
    static_configs:
      - targets: ['119.28.233.229:9615']

remote_write:
  - url: "http://influxdb:8086/api/v1/prom/write?db=prometheus"

remote_read:
  - url: "http://influxdb:8086/api/v1/prom/read?db=prometheus"

2.2 Grafana配置

2.2.1 配置修改

主要是修改[database]栏位，其他配置按需修改

# grafana.ini
[database]
type = mysql
host = 172.29.0.1:33306
name = grafana
user = jason
password = ruan
url =

2.2.2 账号创建

mysql> CREATE DATABASE grafana DEFAULT CHARACTER SET utf8mb4;
mysql> CREATE USER 'jason'@'%' IDENTIFIED BY 'ruan';
mysql> GRANT all privileges ON grafana.* TO 'jason'@'%';
mysql> FLUSH PRIVILEGES;

2.3 Docker构建脚本

# docker-compose.yml 
version: '2'

services:
  prometheus:
    image: prom/prometheus:v2.20.1
    hostname: prometheus
    container_name: prom
    volumes:
      - /usr/share/zoneinfo/Asia/Shanghai:/etc/localtime:ro
      - ./prometheus.yml:/etc/prometheus/prometheus.yml
      - prometheus_data:/prometheus
    command:
      - '--web.enable-lifecycle'
      - '--config.file=/etc/prometheus/prometheus.yml'
    ports:
      - '9090:9090'
    networks:
      prometheus:
        aliases:
          - prometheus
        ipv4_address: 172.29.0.2
    logging:
      driver: json-file
      options:
        max-file: '3'
        max-size: 100m

  grafana:
    image: grafana/grafana:7.1.2
    hostname: grafana
    container_name: grafana
    volumes:
      - /usr/share/zoneinfo/Asia/Shanghai:/etc/localtime:ro
      - grafana_data:/var/lib/grafana
    environment:
      - GF_SECURITY_ADMIN_PASSWORD=ruan
    depends_on:
      - prometheus
    ports:
      - '3000:3000'
    networks:
      prometheus:
        aliases:
          - grafana
        ipv4_address: 172.29.0.3
    logging:
      driver: json-file
      options:
        max-file: '3'
        max-size: 100m

  influxdb:
    image: influxdb:1.8.1
    hostname: influxdb
    container_name: influxdb
    volumes:
      - /usr/share/zoneinfo/Asia/Shanghai:/etc/localtime:ro
      - influxdb_data:/influxdb
    ports:
      - '8083:8083'
      - '8086:8086'
      - '8090:8090'
    networks:
      prometheus:
        aliases:
          - influxdb
        ipv4_address: 172.29.0.4
    logging:
      driver: json-file
      options:
        max-file: '3'
        max-size: 100m

networks:
  prometheus:
    driver: bridge
    ipam:
      config:
        - subnet: 172.29.0.0/16

volumes:
  grafana_data: {}
  prometheus_data: {}
  influxdb_data: {}

2.4 组件启动

$ docker-compose -f docker-compose.yml up -d
Starting prom ... 
Starting prom
Starting influxdb ... 
Starting prom ... done
Starting grafana ... 
Starting grafana ... done

2.5 Influx配置

2.5.1 创建账号
