7. 运维监控

7.1. 概述

长安链采用了普罗米修斯（Prometheus）的监控体系，提供了脚本文件，帮助用户快速搭建基于Docker的普罗米修斯可视化监控环境，并基于该环境进行长安链节点的可视化监控。

7.2. 环境依赖

7.2.1. docker

centos系统

参考：https://docs.docker.com/engine/install/centos/

$ yum install docker-io
$ service docker restart
Redirecting to /bin/systemctl restart docker.service

ubuntu系统

参考：https://docs.docker.com/engine/install/ubuntu/

 $ sudo apt-get remove docker docker-engine docker.io containerd runc
 
 $ sudo apt-get update
 
 $ sudo apt-get install \
    apt-transport-https \
    ca-certificates \
    curl \
    gnupg \
    lsb-release
 
 $ curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg
 
 $ echo \
  "deb [arch=amd64 signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/ubuntu \
  $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
 
 $ sudo apt-get update
 
 $ sudo apt-get install docker-ce docker-ce-cli containerd.io

7.2.2. docker-compose

参考：https://docs.docker.com/compose/install/

$ sudo curl -L "https://github.com/docker/compose/releases/download/1.28.6/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
$ sudo chmod +x /usr/local/bin/docker-compose

7.3. 操作步骤

7.3.1. 链启动

详细说明，请见【快速入门】，这里描述下关键步骤

注：配置文件chainmaker/config/config_tpl/chainmaker.yml的monitor开关需要开启，默认是开启状态
monitor:
  enabled: true

# 进入脚本目录
$ cd chainmaker-go/scripts

# 创建单链4节点集群配置文件及证书
$ ./prepare.sh 4 1

# 生成安装包
$ ./build_release.sh

# 启动链
$ ./cluster_quick_start.sh normal

# 查看节点启动情况
$ ps -ef|grep chainmaker
30219  2326  3 17:56 pts/5    00:00:03 ./chainmaker start -c ../config/wx-org1.chainmaker.org/chainmaker.yml
30239  2326  4 17:56 pts/5    00:00:03 ./chainmaker start -c ../config/wx-org2.chainmaker.org/chainmaker.yml
30256  2326  4 17:56 pts/5    00:00:03 ./chainmaker start -c ../config/wx-org3.chainmaker.org/chainmaker.yml
30277  2326  4 17:56 pts/5    00:00:03 ./chainmaker start -c ../config/wx-org4.chainmaker.org/chainmaker.yml

7.3.2. 配置修改

7.3.2.1. 配置Prometheus监控目标

配置文件路径：chainmaker-go/monitor/prometheus.yml

修改以下配置：

job_name：为节点的org_id

targets：为节点地址

  - job_name: 'wx-org1.chainmaker.org'
    scrape_interval: 1s
    static_configs:
      - targets: ['172.29.0.1:14321']
  - job_name: 'wx-org2.chainmaker.org'
    scrape_interval: 1s
    static_configs:
      - targets: ['172.29.0.1:14322']
  - job_name: 'wx-org3.chainmaker.org'
    scrape_interval: 1s
    static_configs:
      - targets: ['172.29.0.1:14323']
  - job_name: 'wx-org4.chainmaker.org'
    scrape_interval: 1s
    static_configs:
      - targets: ['172.29.0.1:14324']

7.3.2.2. 配置Grafana

配置文件路径：chainmaker-go/monitor/grafana.ini

主要是修改[database]栏位配置，其他配置按需修改

[database]                            
type = mysql                          
host = 172.29.0.5:3306                
name = grafana                        
user = chainmaker                     
password = chainmaker                 
url =  

7.3.3. 组件启动

$ docker-compose -f docker-compose.yml up -d
Creating network "monitor_prometheus" with driver "bridge"
Creating volume "monitor_prometheus_data" with default driver
Creating volume "monitor_influxdb_data" with default driver
Creating volume "monitor_grafana_data" with default driver
Creating volume "monitor_mysql_data" with default driver
Creating mysql ... 
Creating influxdb ... 
Creating influxdb
Creating influxdb ... done
Creating prom ... 
Creating prom ... done
Creating grafana ... 
Creating grafana ... done

7.3.4. 配置Influx

7.3.4.1. 创建账号和数据库

$ docker exec -it influxdb bash
root@influxdb:/# influx
Connected to http://localhost:8086 version 1.8.1
InfluxDB shell version: 1.8.1
> CREATE USER chainmaker WITH PASSWORD 'chainmaker' WITH ALL PRIVILEGES;
> CREATE DATABASE prometheus;

7.3.4.2. 查看表

> use prometheus;
Using database prometheus

> show measurements;
