一、概述

IDC机房测速工具，由3个组件组成：
smokeping：主要负责采集数据
prometheus：主要负责存储数据
grafana：主要负责展现数据
smokeping采集数据之后存储到rrd文件，然后通过脚本把数据提取出来，格式化之后发送到prometheus，然后通过grafana展示出来

使用环境: Centos7 python2.7

二、使用

cd /tmp
git clone https://github.com/Spider-Zhong/idcping-smokeping.git

（1）smokeping 安装单机版：

cd /tmp && wget -N --no-check-certificate https://github.com/raw/ILLKX/smokeping-onekey/master/smokeping.sh && bash smokeping.sh

smokeping的家目录：

smokeping_home_dir=/opt/smokeping

创建config文件，并且配置全国各区域ip监测点

cd $smokeping_home_dir/etc
cp -rf /tmp/idcping-smokeping/smokeping/* ./

监测点主要由国内的三大运营商的IP站点组成，也可以自定义需要检测的站点

启动：

bash /tmp/smokeping.sh

（2）安装prometheus pushgateway

curl -s https://packagecloud.io/install/repositories/prometheus-rpm/release/script.rpm.sh | sudo bash
yum -y install prometheus2 pushgateway python python-pip python-rrdtool
systemctl status prometheus
systemctl start prometheus
systemctl start pushgateway
firewall-cmd --zone=public --add-port=9090/tcp
firewall-cmd --zone=public --add-port=9091/tcp

配置prometheus.yml

vim /etc/prometheus/prometheus.yml

global:
  scrape_interval:     60s
  evaluation_interval: 60s
 
scrape_configs:
  - job_name: prometheus
    static_configs:
      - targets: ['localhost:9090']
        labels:
          instance: prometheus

  - job_name: pushgateway
    static_configs:
      - targets: ['localhost:9091']
        labels:
          instance: pushgateway

把smokeping采集的数据通过rrdtool读取之后，按照一定的格式推送到prometheus的gateway，时间间隔是1分钟 Ps: 请务必检查运行环境 模块是否安装 requests rrdtool

pip install requests
cp /tmp/idcping-smokeping/prometheus/collection_to_prometheus.py $smokeping_home_dir
touch /tmp/smoking_pushgateway.log

在/usr/local/smokeping/collection_to_prometheus.py中，按照实际情况配置3个参数：

'LOG_FILE' : '/tmp/smoking_pushgateway.log'             # 日志文件  
'prometheus_gateway' : 'http://localhost:9091'     # Prometheus gateway地址  
'data_dir' : '/opt/smokeping/htdocs/data'                # smokeping rrd文件的存放地址  

配置crontab计划任务

crontab -e 

* * * * * python /opt/smokeping/collection_to_prometheus.py

（3）grafana

安装

wget https://dl.grafana.com/oss/release/grafana-6.1.6-1.x86_64.rpm 
sudo yum localinstall grafana-6.1.6-1.x86_64.rpm 

将模板grafana/ping_monitor.json 导入grafana即可，效果大概是这样
